We have three dogs; a Lab and two Collies, they all eat the same food and they all taste pretty much the same.
@zetacable this is from Research Gate:
"There were no differences (P > 0.10) in sperm motility in either neat or extended samples at 24 h from EE dogs and wolves, although motility of the wolf neat samples declined more rapidly (P < 0.05). However, there were differences (P < 0.01) between EE and manually collected dog semen in motility at 24 h, in both the neat and extended samples. Therefore, general motility patterns of dog and wolf semen collected by EE were similar,". Of course wild wolves eat differently to domestic dogs and even between human males there are differences in taste, I agree, but I think genetically, the differences between wolves and domestic dogs is fairly small, after all they do inter-breed. My original point was that between breeds, there is little variation in taste, it depends on their diet, like humans. I certainly didn't mean that there was any racial difference in humans.
Did you know, that domestic dogs have learnt, by copying humans, to move their eye-brows? Wolves don't do that. I was surprised by that little titbit.
