Introducing a Cat and a Dog (by Sherry Woodard)
Some dogs do fine living with cats; others simply cannot live safely with felines. Even if the dog has cat experience and the cat has lived with a dog before, proceed cautiously during the first introduction. It’s best to have two people present, one to intervene with each animal if necessary. If you have more than one dog, introduce each dog separately to the cat.
The dog should be held on a loose lead. One person should watch the dog’s body language and the other should watch the cat’s. If the cat is not acting aggressively (raising his back, hissing) toward the dog, he can be allowed to move around freely. A cat is rarely a threat to a dog, but there are some cats that will meet dogs aggressively. If the dog is not acting aggressively toward the cat, then you can ask the dog to sit, or lay down and stay, while the cat moves around freely, sniffing the dog if he wishes. The dog should be praised and rewarded if she ignores the cat.
If the dog has a strong prey instinct, she will become very focused; she’ll stiffen and stare, and may start barking or whining. If you see these signs, do not allow the dog near the cat. Especially, do not allow the dog to chase the cat. If the dog lunges and tries to chase the cat, you should try a different strategy for getting them to share space.
Instead, put the cat in a bedroom with a tall baby gate across the door. Give the kitty all needed supplies – litter box, food and water. Allow the dog to view the cat briefly through the gate, and then get the dog to focus on something else, like playing or practicing commands. Praise and reward the dog for being able to focus elsewhere. Continue to give the dog short viewings of the cat throughout the day.
The hope here is that the dog will eventually lose interest in the kitty. In some cases, the dog will lose interest in the cat within a couple of hours, but some need days, and others simply will not be able to share a space safely with a cat. If you don’t feel you can trust your dog around your cat, you should keep them apart. Many dogs can injure or kill a cat very quickly, and dogs can also be injured by cats (eye injuries are not uncommon).
