Should a male dog with a food allergy be used to stud? - Page 9

aaykay, I think that is how evolution through adaptation works. Dogs, of all breeds, are being forced to eat what they have not been genetically engineered to eat. Grain is not natural for a dog to eat, they are not ruminants and they don't have a gut long enough like horse does to digest grain. Yet, that is what is forced on them. The dog food industry is finally waking up and realizing a lot of dog owners are refusing to feed their beloved animals floor sweepings and now have "grain-free" products available. Some dogs, through adaptation , can tolerate the grain and other non-dog food ingredients. But the ones that get loose stools because their body is ridding it's self of indigestible stuff, does not mean that dog has a defect. It may indicate that instead of letting it sit in the gut and rot, causing bloat, the dog's system is rejecting it, as it should.

I guess I should have said there are disappointments in breeding dogs EVEN when you do it all right.

I think a mutation occurs when a DNA gene is damaged or changed; that gene will now carry an altered message. Most mutations are lethal so they don't reproduce themselves for very long.
