Dogster, it is not that unusual to find adult dogs who dislike puppies. Zac is by no means, is the only adult dog on this board who dislikes puppies. Many dogs dislike puppies. I've seen posts by other members here, who have friendly, normal dogs who dislike puppies. Sometimes, even adult dogs who DO like puppies, find themselves 'correcting' puppies who don't know any better than to pester and pester an adult who says "back off" etc etc. In general, puppies have few manners. But some dogs DO like puppies. I bet, mayyyyyyyyybe some of this has to do with if a dog grew up around many puppies, or got to meet puppies when he was still young dog, who knows? Just a guess. Plus, Zac is having to LIVE WITH this puppy. which is kind of different to a dog, than just playing with a puppy in someone else's yard. some dogs dislike cats, some dogs grew up around cats. Maybe it is something the same there, as far as puppies go. (not sure) But, you are right, Dogster, sometimes getting DogA to accept DogB can be complicated, especially if DogB is a puppy!
