I have an eight year old male non neutured golden retriever who is gentle and laid back. I have recently taken my son's 3 month old American Bulldog. My question, will these dogs get along?
Although he is adorable, my fear is that when he gets older he will hurt my golden. I don't know if I should try to find him a good home or I should keep him.
Unfortunately there's no simple answer to this because so much depends on the individual dogs involved, not just the breeds.
American Bulldogs are a fairly assertive breed, and can tend towards dominance, although they're not 'aggressive' as such. They're usually fine with children (school-age and older) and dogs of the opposite sex, but it is possible that this pup will attempt to dominate your older dog when he's mature. If this led to fighting, the American Bulldog would definitely have the advantage physically.
Neutering the pup may help reduce these tendencies, but is no guarantee. Also, there are submissive, gentle AB's just as there are dominant Goldens, a lot depends on the dogs themselves.
I can only give a personal opinion, and I've not met the dogs myself so it's a general one. As this is a young puppy, he will adjust to a new home fairly easily, and if I were in your position I would probably try to find him a good, loving home where there isn't another male to compete with.
One word of caution though.... if you decide to attempt to find him a new home, be careful when you're considering prospective owners. These big, strong dogs can sometimes attract owners who want them for the wrong reasons. I don't necessarily mean fighting, but maybe to 'look tough' or give a macho appearance, even as 'guard dogs' etc. American Bulldogs really aren't a breed for first-time dog owners either, as they need a lot of training and socialization. They're sensitive and loving dogs though, so this pup needs a good home, with someone who is used to caring for dogs, and has the right attitude. It's always a big responsibility finding a pup a new home!
Anyway, I wish you the best of luck with whatever you decide to do. Hope this helps you at least a little.
