I adopted Payton about 6 weeks ago. He is a little over a year old. He was in a foster home with 4 other dogs, and I was told he got along with them great. He is awesome at the dog park, a bit shy at first, but once he finds he feels comfortable, he plays and plays and has never shown aggression. He has been good on walks, but once in a while...he will see a dog coming from the other way and will start stalking it. He will start getting low and walking real slow...when we get close to the dog he will sniff it's behind and sometimes start trying to play with him, at least it seems like he is trying to play, and not chase/hunt. He usually has his tail wagging like he is happy to see another dog once he gets closer. It makes me nervous though, when he is in the stalking pose and I'm just not sure how to act. I feel as if I act scared and pull him the other way he will just get more interested... I get afraid to get close to the other dog in fear that one of these days he might hurt them... I've seem him act so great with other dogs, the stalking pose just make it look like he wants to attack! I know they have a strong prey drive, could it be that he's going through those motions but then stops before the bite/kill bite steps? We do have many cats in the neighborhood that roam free and drive him crazy...Any advice would be appreciated! Thanks!
