It didn't feel minor, but there was no blood and I don't think any physical injury, but mentally it was a big deal. (Both are male animals)
So my sister and her dog (2-year old Aussie) moved into my place in May. He's mostly a good boy but also he doesn't listen sometimes to anyone. He has a lot of anxiety when he leaves the apartment. He loves watching(read fixating) on the cat through the baby gate we step up for them. The cat now has to live in my bedroom and master bathroom and the dog is not allowed in here.
Tonight I was playing with my cat in the bedroom, baby gate closed, and I guess the dog was watching us, freaked out that the cat was playing/running around and some how opened the baby gate. I guess when he jumped at it he hit it just right? He hasn't done that before.
Anyway, the cat started running away into the bathroom and the dog chased right after the cat. He cornered the cat and was being mouthy and the cat was battling him away. It was all just a lot of chaos and I think the cat's paw might have landed in his mouth but he never bit down. I pulled the dog off the cat and gave him a smack on the back of the head that I don't think he noticed and the cat ran away and the dog still tried to run after him but I was holding on to the dog still. My sister came into my bedroom at that point and was so mad that he did that. She yelled at him and put him in his crate for the night. I told her what I saw and what I didn't see and how I was across the room when it happened and tried to get to him as soon as possible. I think we were both shocked. She didn't really say anything. The cat didn't want to come near me at first and I felt horrible. He's closer to me now and less upset, mostly ok. He doesn't seem to have any injuries.
I don't know what to do about the dog. My sister loves him to much for me to say get rid of him. I think she needs to take him to training class. We had been thinking about it for a little while cause he doesn't like leaving the apartment and he likes to jump on people. But now I want the dog to go ASAP. I never want something like that or worse to happen to him again. We are moving to a new place next week and I do think he will be calmer there because it's less busy of a street. However, that doesn't mean he will behave with the cat and this cat is my whole world. I love him to death. I can't seem to calm down from this and I feel like out of all of the people and animals in this, I'm the one that's most upset! (Although I don't want to speak for my sister, she has her room and I don't know how she feels)
What do you think we should do?
