Beware Thinking Like Lamarck
October 26, 2008
Lamarck and Darwin
Jean-Baptiste Lamarck was an 18th century French naturlist who developed the first coherent theory of organic evolution. That is to say, he developed a testable scientific theory of how organisms evolve into other oganisms through time without divine intervention. Lamarck incorporated into his theory the common belief of the day that organisms can inherit the acuired characteristics of their parents. He belived in something he called l’influence des circonstances or the Adaptive Force which causes organisms to adapt to changes in their environment. Those acquired adaptations are then passed on to the offspring of the organism through sexual reproduction.

Jean-Baptiste Lamarck and Charles Darwin
Under Lamarck’s theory, for example, a blacksmith could develop a right arm that was stronger and larger than his left arm. The son of the blacksmith would inherit this characteristic and develop it further and so on and so forth until you get a race of blacksmiths with one giant arm. This is nonsense. An organism cannot pass on acquired traits to its offspring.
In the 19th century, Charles Darwin, showed that evolution can happen without the deus ex machina of an invisible adaptive force. A population of organisms has random variation in traits. All of the organisms cannot survive and reproduce. Only some of the animals successfully reproduce themselves (for whatever reason) and, in the case of species that reproduce sexually, only some of the possible mating combinations occur. This Natural Selection operating on the population is the engine that drives evolution, rather than an Adaptive Force. The other feature of Darwinian evolution is “descent with modification” or the idea that sometimes the offspring in the new generation have a characteristic not found in the parents. We usually call descent with modification mutation. Mutation and differential reproductive success are the forces that drive evolution.
The thing is, though, that Lamarckian inheritance is very intuitive to people. I often observe people speaking about selection and evolution, especially with respect to purebred dogs, in Lamarckian terms without realizing that they are doing it. Whenever we think about how purebred dogs have changed through time, we need to stop and remind ourselves that animals cannot transmit acquired characteristics to their offspring. We change the characteristics of breeding populations only by selecting which specimens will breed forward to the next generation. Nothing else matters.
Evolution is driven by differential reproductive success. Traits acquired during the life of an animal cannot be passed on to their offspring.
Myth: Azawakh will not Fetch
October 22, 2008
If you spend much time researching Azawakh temperament and behavior you are likely to read that they will not retrieve or “play fetch”. It’s not true. An Azawakh can learn to play the fetch game.
It is true that fetching is not an obsession with Azawakh like it is with many other “sporting” breeds. Azawakh have to learn that “fetch” is a fulfilling form of play and the dog has to be in the mood to play the game.
“Retrieve” is a natural behavior and a standard canid motor pattern. Wild canids “retrieve” game and bring it back to pups in the den, for example. Azawakh have this motor pattern, but it isn’t hypertrophied in the way that it is in modern gun dogs. The behavior is there but it is far from a compulsion. Azawakh can and will retrieve to hand. If the game is fun, the dog will play. It requires the right relationship between dog and handler.

Exciting Whelp at Idiiyat-es-Sahel
October 17, 2008
Tirout has whelped 5 pups at Idiyyat-es-Sahel. The puppies are sired by Tigidit Fasiqqi. I’m tremendously excited about this litter first because Tirout and Fasiqqi are great dogs to be around and beautiful, but also because they represent an injection of new blood from the Sahel that is essential for the survival of healthy Azawakh.
Tirout was imported from the Sahel by the Association Bukinabe Idi du Sahel (ABIS) 2007 expedition. Fasiqqi is the son of a dog collected in a previous expedition. They are also unusual in Western breeding because they carry recessive color combination genes which have been eliminated in the West by a combination of selective breeding and the random chance that the original foundation dogs were a particular color combination. While color is superficial, it is visually striking. Two of the puppies are particolored. They are mostly white.

Tirout's particolor puppies
In the 1980s and 1990s, the Azawakh gene pool in the West became increasingly restricted. In aggregate, the inbreeding coefficients were steadily increasing while the ancestral loss coefficients were declining. The inbreeding coefficient is a rough measure of the genetic sameness of a dogs ancestors. The ancestral loss coefficient is a measure of the number of distinct ancestors relative to the whole population. Rising inbreeding coefficient tends to indicate increasing sameness. Falling ancestral loss coefficient indicates that breeding lines are being eliminated from the gene pool.
This graph shows an alarming bottle-necking trend which can only end very badly for the dogs. Consider the Basenji, which is closely related to the Azawakh. Contemporary Western Basenji have a very high incidence of a number of serious genetic ailments including digestive disorders, hip displasia, progressive retinopathy (blindness) and Fanconi’s syndrome (kidney failure). They also no longer look very much like hounds in the Congo. Breeders must out-cross back to desert bred dogs or there is no doubt in my mind the Azawakh will suffer a similar fate.
These whelps are part of the key to maintaining Azawakh as a viable, healthy breed. I am very excited about these puppies.
Congratulations, Daoud.

What’s in a Name Part 3: Azawakh
October 10, 2008
Azawakh is not Tamasheq
Azawakh or azaouak comes from the Djerma language. It means “Land of the North”. The Djerma are a considered to be a branch of the Songhai people, but they may were actually assimilated during the Songhai Empire in the 16th century. Many Djerma were displaced from what is now a Fula region, Lac Debo in Mali. They eventually settled well East of Lac Debo near Niamey in what is now Niger. The Azaouak Valley is almost directly to the North of Niamey.
Not Just a Name for Dogs
In addition to being the name of a breed of dog, Azawakh, is a strain of Zebu cattle characterized by long lyre-shaped horns and a hump. The cattle are thought to have arrived in the Sahel around the late 7th century BCE. Other names for these cattle are Bororo, Tuareg, Adar, Tagana and Azawaje.
I have the sense that both breed names were synthesized by Europeans in the post-colonial period of the last century. Neither Azaouak (meaning a breed of cattle) nor Azawakh (meaning a breed of hound) is used by any local people. Both words are really a shortening of a phrase:
- Cattle of Azawakh
- Hounds of Azawakh
If I Have More than One are they Azawakhs?
No. The Plural of Azawakh should still be Azawakh. Remember that Azawakh is the name of a place, the Azawakh Valley or the Land of the North. When we use the Azawakh as a breed name, it is really just a shortening of hound of Azawakh. Where the hound of part is understood. The plural is hounds of Azawakh. The hounds of part is still understood even if you don’t say it. It would never be hound of Azawakhs nor hounds of Azawakhs.
As another illustration, consider if we replace Azawakh with Canada. We now have an imaginary breed of animal called Canada. Can you imagine calling a pack of them Canadas?
The other option would be a construction like Azawakhians or Azawakhans, which just seems horrifying.
The plural of Azawakh should remain Azawakh.
Mandatory Vaccination Laws Need Updating
October 8, 2008
The Reminder
I received a postcard in the mail recently from our veterinary hospital. Azelouan is due for his vaccinations. I was under the impression that annual booster shots were no longer de rigeur so I called up the vet. It turns out that his initial vaccine doses were designed by the manufacturer for puppies and have a guaranteed efficacy period of one year. All the research I have seen suggests that a final booster should be given at one year, but that isn’t enough to be legal.
DC Law requires valid vaccinations for Distemper, Parvovirus and Rabies for all dogs.* In order to be valid the vaccinations have to carry a guarantee of efficacy from the manufacturer. The longest efficacy guarantee available is for three years. He has to get boosters every three years in perpetuity. Why not measure whether the vaccinations are actually necessary through antibody titers? While they are happy to do titer tests on Azelouan, the District of Columbia will not accept them as legal proof of vaccination. The law requires that vaccinations are valid only if there is a manufacturers warranty of efficacy behind them.
Well.
Perverse Incentives
Vaccine manufacturers and Veterinarians have an incentive to sell vaccines to pet owners. This is the reason that for many years we all had annual vaccination visits. Recent public concerns about the potential connection between excessive vaccination and cancer and immune disorders has led to the development of 3-year vaccines. I have a strong suspicion that there is no difference between the 1-year labelled vaccine and the 2-year labelled ones.
The point is that both the providers of the vaccine and the veterinarians have no incentive to stop giving vaccines. Quite the contrary, they get paid every time someone brings in a dog to get vaccinated. Mandatory vaccines are a guarantee that clients will show up to the office and spend money.
There is strong evidence that after the core vaccinations series is complete at 1 year, most dogs have lifetime immunity.
First, Do No Harm
The first principal in human medicine is to do no harm. We don’t give children antibiotics for a sore throat unless a throat culture indicates the presence of a streptococcus infection. We shouldn’t be vaccinating just in case or as a way to incentivize clients to show up for well-puppy visits. Vaccines are not risk-free.
Instead of vaccinating in perpetuity, the law should be modified to allow an antibody titer instead.
Below is the minimal vaccination schedule developed by Jean Dodd, DVM.
| Recommended Vaccination Schedule | ||||
| Vaccine | Initial | 1st Annual Booster | Re-Administration Interval | Comments |
| Distemper (MLV) (e.g. Intervet Progard Puppy) |
9 weeks 12 weeks 16 – 20 weeks |
At 1 year MLV Distemper/ Parvovirus only |
None needed. Duration of immunity 7.5 / 15 years by studies. Probably lifetime. Longer studies pending. |
Can have numerous side effects if given too young (< 8 weeks). |
| Parvovirus (MLV) (e.g. Intervet Progard Puppy) |
9 weeks 12 weeks 16 – 20 weeks |
At 1 year MLV Distemper/ Parvovirus only | None needed. Duration of immunity 7.5 years by studies. Probably lifetime. Longer studies pending. |
At 6 weeks of age, only 30% of puppies are protected but 100% are exposed to the virus at the vet clinic. |
| Rabies (killed) |
24 weeks or older | At 1 year (give 3-4 weeks apart from Dist/Parvo booster) Killed 3 year rabies vaccine | 3 yr. vaccine given as required by law in California (follow your state/provincial requirements) | rabid animals may infect dogs. |
Perform vaccine antibody titers for distemper and parvovirus annually thereafter. Vaccinate for rabies virus according to the law, except where circumstances indicate that a written waiver needs to be obtained from the primary care veterinarian. In that case, a rabies antibody titer can also be performed to accompany the waiver request.
*I was told yesterday by the veterinary technician that DC law required Parvo, Distemper and Rabies vaccinations. Today, I got clarification from the actual veterinarian that DC only requires Rabies. The hospital is willing to perform titers in lieu of vaccination upon request but does not accept responsibility for any legal rammifications with a failure to comply with city orndinances. It’s obvious that nobody knows what the real rules are. I looked it up in the DC code 8-1804: “the owner of the dog shall have the dog vaccinated against rabies and distemper”.
Balinitis
October 7, 2008
Frustrating Drips
For the past few months, my juvenile male Azawakh, Azelouan, has been dripping “semen” all over the house. At one point, I mentioned the dripping “semen” problem to a few people who I thought would be knowledgeable and they chalked it up to “testosterone poisoning.” I didn’t think too much of it. We figured the poor guy was loaded up with testosterone and just way oversexed. It was starting to drive my wife crazy, though, because cleaning up the waxy drips is a monster chore that requires a kind of degreaser to remove them from hardwood floors. When he shakes himself the drips are often flung onto the walls for an extra disgust-factor. Suffice it to say that if a way could be found to turn off the dripping faucet of dog “semen”, it would make me a hero.
To cut quickly to the chase, the stuff dripping from my dog’s penis was not actually semen, it was pus. The poor guy was suffering from a condition in dogs called Balinitis: an infected penis sheath. Fortunately, there is an easy home remedy that almost always cures the infection.
Stumbling upon a Solution
A few months ago, I purchased an out of print book, used, on the Amazon.com marketplace. It is called Care of the Racing Greyhound. My dogs are not Greyhounds, but this book is very interesting because it is dense with information about canine sports injuries, particularly coursing injuries. It also has medical information not normally found in books for the general population. This book is extremely dense and I had set it aside, having read about half of the thing. I was bogged down in sprains, strains and massage therapy. After running the 10-miler, I happened to pick it up and the book fell open to page 314 which, unbelievably, had a picture of Azelouan’s problem (shown above).
Balinitis can apparently have a number of root causes from masturbation to anabolic steroid use to excessive vitamin E in the diet. The end result is an infection in the penis sheath that can also lead to cystitis and even kidney infection. Most dogs that have balinitis with a discharge also develop tonsillitis. Fortunately, the cure is pretty simple and usually does not require antibiotics or a trip to see the veterinarian. In the vast majority of cases, just rinsing the sheath out with an antiseptic disinfectant cures the problem.
Treatment
Flush the penis sheath out with a dilution of 1 part Betadine in 9 parts water, 1 teaspoon of Hibitane in 1 pint of water or quaternary ammonium disinfectants. Use a syringe without a needle or a pediatric enema bottle to flush the area for at least a minute. The program calls for cleaning the penis sheath once daily for three days followed by every other day for two to three weeks. According to the book, the vast majority of dogs resolve with simple rinsing. If the infection is resistant, it recommends trying a switch to a different antiseptic. If the infection is stubborn, it may require an antibiotic like amoxicillin with clavulanic acid (Clavamox).
I opted for Betadine dilution because we have that in the house. The day after the first treatment, the discharge was nearly gone. After the second treatment, the drip was gone and the tip of his sheath has become much less red.
Azelouan doesn’t really enjoy having his penis washed out and I can’t say that I’m that excited about it either. On the other hand, he is clearly less agitated and is spending a lot less of his time peeing and licking himself. He seems quite relieved. Actually, he’s overjoyed. Christie, too, is overjoyed that Azelouan is no longer splattering disgusting waxy drips all over our house.
Score one for biblioholism!
Azawakh Training
October 6, 2008
I’m not talking about training your Azawakh. I’m talking about your Azawakh training you. Specifically, as an exercise partner. After my second daughter was born, I put on a few pounds and had some unfortunate waiste expansion. Over the last several months, my young Azawakh has been running with me. It’s like motorpacing – Azawakh pacing. He always wants to run faster, farther, more. I’ve been able to tighten my belt two notches. Yesterday, I ran the Army 10-miler and set a personal best time. Unfortunately, the Azawakh is not able to train me to be smarter.
Since Christie and I were both running the race, we needed a babysitter to watch the kids (and hounds). Fortunately, Cherish was game to babysit and she was willing to be picked up at 6:30 AM. Unfortunately, I hit the snooze bar a few times and that led to a cascade of unfortunate events. I picked up Cherish about 6:45. We were running late but it was manageable.
We planned to take the metro (subway) to the start at the Pentagon. I grabbed a fistful of change from the penny jar and we hustled off to our local metro station. I pumped all my quarters into the machine and it spit out a $4 paper fare card – which was more than enough to get to the Pentagon and back. Then we got on the wrong train.
I’ve lived in Washington, DC for over 10 years, now. You would think I would have a clue which metro trains go to the Pentagon. But no. We hopped on the first train which was green and we should have been on Yellow. I told Christie that they both go the same place. Well, that’s sort of true as long as you don’t want to actually leave DC. The last stop where the Yellow and Green lines are the same is L’Enfent Plaza. When we pulled up to the Washington Yard station stop, we realized we were in the very wrong place. (The Washington Navy Yard is in Southeast DC and is about as far from the Pentagon as our house was to begin with; just in a different direction. ) By this point it was 7:55 AM and the race begins at 8 AM.
We got out and switched trains to get ourselves back to L’Enfent Plaza so that we could switch again to the Yellow line. We arrived at the Pentagon about 8:30. We sprinted across the parking lot just in time to join the very back of the pack as they crossed the starting line over 33 minutes after the leaders.
I had a great 10-mile run. I’m not really a fast runner but each of my mile splits were between 8 and 9 minutes. I even had some energy left for the last two miles from the Holocaust Museam across the bridge of death. The last two miles of the race are actually on I395. The bridge is heavily canted and rolls up and down. It is a horrible and depressing thing to run across, but I made it to the finish and felt pretty good. I could almost feel Azelouan pulling me along and looking up at me with disgust at how slowly I was moving.
I felt pretty good about my personal best time and everything. I was pretty much euphoric until I tried to fish out my metro card. After being up next to my sweating body for an hour and twenty-five minutes, the paper card really resembled nothing more than a couple of spit wads. There was no possible way that I could use that thing. Of course, if I had been smarter, it might hae occured to me that quarters are waterproof.
If I had saved half my quarters for the return journey, I would not have found myself walking 5 miles home from the Pentagon after running 10. To recap, I was 30 mintes late for the race and had to walk home. In both cases my misfortune was caused by my utter failure to engage the grey matter. My Azawakh was good for training my body but he hasn’t made me smarter.
