i read some statistics, and the fourth dog on the list that has to suffer from aggression problems due to inbreeding is the golden retriever....
Apparently the reason dogs can be aggressive and such due to inbreeding is because of the limited gene pool. Deleterious genes become widespread and the breed loses vigor.
I'm guessing that aggression in dogs that have been inbred is more like a mental dissablity...like if two sibling humans had a child, it would most likely be mentally retarded...
Male goldens are approx. 65-75 pounds and females are approx. 55-65 pounds according to AKC.
How many puppies were in his litter?
