Alright, we have 3 full grown cats, 1 kitten. We just adopted a dog (Pit bull) named Beau. Brought him home earlier today. He has been GREAT so far. He definitely needs some training (how to walk on a leash, not to jump, things like that), and my hubby and I will be working on that for the next few weeks. He has been Great with the kids.. we have a 4 yr old and a 1 1/2 yr old. Now with the cats, he wants to play with them, and they want nothing to do with him. Right now, I have the main floor of the house gated (both stairwells are gated actually). That way the cats can be upstairs or down without him being anywhere near them. I do not want it to stay like this for long. So, any tips on how to get them to get along, best ways of introducing them to each other would be much appreciated! Both times he's seen one of the cats he just gets excited and gets into a play stance. The last time I had to hold him by the collar because he was about to chase the cat.. and it just made me nervous (even though he has shown NO agression at all). For anyone who wonders, I've owned 1 pit bull in the past (at my parents house), raised him from a 4 week old pup (he was dumped at a petsmart) and he is now about 7 years old. So, this is my first time getting a dog that is full grown (1 1/2 yrs old roughly) and having to re-train what he already knows.
