Just adopted a 3 month old mutt (Boxer/Hound/Terrier/everything) from the Nashville Humane society (NHS) ~2 wks ago. He was separated from his mom at 6 wks. Kept in a foster home until 10 wks. Then given back over to the NHS where he was neutered and given his shots. He spent ~2 wks in the pound before we picked him up.
Everything is going great with the crate training and potty training. He's a little skittish about other people, but within a few seconds with assurance from us, he warms up to everyone. Even children (nobody younger than 6, though)
BUT, we've gone on two quick walks at a local park where we crossed paths with fellow dog owners. The first time was with a larger dog that was well behaved and was wagging his tail as we approached. Toby (our dog) started to growl and barked for the first time (that I heard). He hid between our legs and we thought maybe we had set ourselves up for failure. So, we diverted paths and walked another way.
The second time, again with an older dog. Again, he seemed friendly. This time, I called out to the owner and told him the plan. My girlfriend held toby and I walked ~5 yard to the other owner and dog. I petted the dog and made sure he was wagging his tail. I then came back to toby, had him smell me, and then slowly walked over to the other dog. Again, same thing. Barking, growling and he even nipped at him. Of course, this made the other dog nip back which caused Toby to yelp, get behind us and growl and bark more.
Is this normal? I don't want to have to worry about him getting into fights at the park. I also plan on getting a second dog at some point. Toby doesn't seem to be aggressive with us or anyone else he meets. THANKS for any help you guys can give!!!
