Our dog is a 10 year old boxer he’s really sweet, he has issues with boundaries as he enjoys to sniff everything and anyone new, about a year ago we took in this stray kitten she was a small calico but she was about 7months, really sweet and loving but a little fiesty towards others , weve introduced her to two other small dogs and it went great. As to our dog it was a bit to much for both, he tried to sniff her tail and she did not like that and slapped him and he tried the same so it didn’t go so well. No one was hurt thankfully and they both calmed down, but ever since we’ve kept them on opposite sides of the house separated by a baby gate. They are able to see each other and they will acknowledge their presence on occasion will also go into each others space when the other is out of the room/house, for example when i walk our dog shell go into his bed to look around or to sit in the couch where he sits and vice versa. About 4 times weve caught our cat in the in the same room as our dog in the middle of the night or when were out just loafing or by the window and he just doesn’t acknowledge her and they both just relax or shell run to the other side, so we just dont say or bother them and let them be. (We walk out of the room in amazement to what we just witnessed...) , other times weve seen her on the baby gate taunting the him or talking to him. Little by little weve been allowing them to roam around together when we’re around them. Our problem is my dog will always seem to keep his eyes locked onto her when we’re in the room but he wont tense up anymore or get that line on his back when hes on guard. A year in.... Is it safe to start letting them co exist? Can I assume that he is just curious at this point. How can I make him loose interest in her, im not sure if its because he hears the bell she’s wearing on her coller.
