We have a 5 month old puppy.
I kind of hoped our cats (8 years old) would get used to him but it's not happening.
I've moved their litter tray and food upstairs where the dog is not allowed, and they have to run across the room where the dog is allowed to get into the garden. One of us holds the dog while the other opens the door.
The dog will chase the cats any chance he gets. They either scarper or a couple of times they have hissed at him.
I've tried having the cat in the room while the dog is on the lead, tried to encourage him to ignore them with treats but no good.
Am I fighting a losing battle?
