Mine will bark and chase after the wifes cat still but its more of a game with them now and the cat wants him to chase him.....They’ve coexisted quite a bit in the same room with the cat up in the window or the perch and the cat doesn’t care anymore. Dog is curious but isn’t doing much other than watch her or sometimes put his front paws up to sniff her or even lick her.
Only issues so far has been twice when the cat jumps down he will go to chase her. So far he’s stopped when told “off” and “place” so that’s good.
Just a bit less tension and the cat not high up would be nice. Progress is being made but it feels slow.
If the dog stops running down the hallway after the cat, the cat literally will run after the dog and the dog will run to my wife and make her pick him up like a bitch.
We put a cat tree in the living room to give the cat a space the dog cant reach but he gives no fucks about the dog and eggs him on more than anything so we're not worried about it at all. Between that and the minimal size difference it's been pretty smooth sailing really.
