When I adopted Z a year ago I was told he was not cat safe. I was told the only cats he had ever seen were barn cats and that they would not be surprised if he had killed at least one at some point. I brought him home anyway despite the fact that I have two cats. I started off with using a muzzle to introduce him to them. I held the cat on my lap and let him sniff and let him see me loving on the cats. When he got too pushy I made him lay down or back off at the very least. I repeated this often. Whenever the cats were present, I kept him on a leash so that I could correct him if needed. Within two weeks, he was pretty good with them, indoors. Outdoors took much more patience and persistence. He would chase the cats and was pretty rough. I was also working on the leave it command at the same time, specifically for that purpose. One of my cats is very dog safe and that helped immensly because the cat would walk up to Z and plop down, roll over, sprawl out and let him sniff. Now they are best of friends and I could not be happier.
On the down side- there is always a chance that a dog may not be able to be cat safe. I believe that it depends on the intensity of their prey drive.
