I would say that in an ideal world breeding dogs with no structural defects or genetic defects would be the best way to go so as not to continue having dogs coming out with those defects in the future.The fact that we still have them means that past breeders either didnt care or didnt notice the defect and try to cull it out in the first place, so that it would be less of a problem or infact virtually irradicated from a certain breeders line of dogs.The show or cur dog fraternity have done this very well , with breeds that had problems with hip dysplasia amongs other defects, and rather than breeding a dog just becasue in all other regards it was a good prospect or could have won some ribbons before the problem was noticeable , they cull them , or at least the serious show breeders do and infact you see peds with the negative hip dysplasia x rays and other fault free tests from these breeders showing prospective buyers of their pups or other breeders wanting a stud from their stud dog that that dogs at least do not carry the faults that serious show breeders regard as unacceptable .
The problem within the apbt fraternity is the fact that there is less attention paid to these type of problems as outlined in other posts, such as faulty hocks or kness etc which becasue a dog was game was overlooked and bred ,which in the long run if you dont try to cull or at least not breed in those dogs with severe structural faults then inevitably they will continue to appear .The thinking should be a little different , instead of worrying that your game dog that has some faults wil be lost to the breeding program and therefore you loose a special dog , is to think that if the dog dropped dead today the world of apbts wouldnt just collapse because that dog died or wasnt bred into the genepool, because then you would look for a specimen that didnt carry the defects and who was also a good game dog to breed instead of the defective dog.
We panic and make silly deicsions based on the idea that that dog is a once in a lifetime specimen and even if its blind deaf and crippled and if we dont breed him we will never see another like him again , which is hogwash .Where there has been one there will be another good dog , the history of this breed is littered with good game fult free dogs so why do we think that we cant breed another one that doesnt carry faults? I for one would never do what a supposed great breeder like gary hammonds has done for 40 years ,and thats breed deaf dogs ,of which there is no good reason to do especially when like hammonds you keep a large yard of similarly bred dogs to choose from , that is just bad breeding practice and very lazy to say the least, and should never be sold to others to breed into there line which he has done , even if i was begged for a dog like that to breed from another breeder i would not sell it to them, i would infact cull dogs with any deafness/ heart defects or blindness without hesitation, the other defects like hocks etc , depending on how obvious and how much they affect the abilty of the animal to move freely as there are varying degrees of severity would then be a choice each breeder knowing their line if they could breed that individual back into the line without making the problems any worse than it already is, but my way would be to not use even those dogs that showed minor strucural defects where possible if i had another dog of similar quality that didnt show those defects, but to breed dogs with severe defects and certainly dogs who are deaf /heart or blind defects is just bad breeding practice and i dont care how good the dog is , if you bred him you can breed another and hopefully if you dont keep adding in defects which no serious breeder in thier breeding program of any breed of animal be it cows horses etc will do and theres a good reason why , and the sooner the apbt fraternity starts thiking like that the sooner we wont be having to talk about what the obvious thing to do is when an animal with genetic defects pops up, and thats CULL IT .
