I have a 4 year old medium sized dog that seems to have anxiety around other dogs. She was in a pretty bad fight with my parents dog over a year ago and hasn’t had much interaction with dogs since. Even going on our walks if a dog barks at her through a fence she wants to go the other way. We recently just adopted an 8 year old pug mix into the family due to sad circumstances with the previous owner. My 4 year old pup seemed a little uneasy at first but now she seems alright with him. Sometimes she’ll growl when he takes her toys from her but she’s getting better. But when I throw the ball around the house for them to play with, if he’s about to grab the ball and she tries to get it first he growls and snaps at her a little. She then hunches down in place and I yell at him due to my anxiety with dog fights (I tried breaking up the fight she had with my parents dog and I got bit pretty bad so I’m automatically over responsive to growling). I’m not sure how to help them get along. They do fine until it comes to playing with a toy together. And sometimes I can’t tell if she’s ready to attack or just back down when he snaps at her. Any ideas as to how to fix this situation? I want them to get along and be friends.
