Help! When shelters do a test to see if a dog will get along with cats, what do they do, and how do they know? Basically I am wondering if there is a way of telling how my pup will transition. Marlee is barking ferociously at Magnet, jumped the gate and lunged at him. Magnet is safe, but terrified and hiding. When he comes out, he does a low crawl. I expect hiding, I expect some barking and stuff, but how do I know if the dog is too aggressive to be around a cat? Marlee is afraid of everything else so I thought she would be afraid of the cat (she was never around cats before).
In the past, my cats and dogs always got along. It wasn't instant. In fact it took a few months, but there wasn't this type of aggression and drive.
