Cats and dogs can be wonderful companions. The key is to start them off right. Here are some tips to get you started.

Try to create a good match. If you're looking to add a dog to your feline home, try to find one with a complementary personality. If you're looking at a shelter dog, find out its history, because you don't want a dog who was an avid cat chaser in his previous life. If your cat is very timid or nervous, don't pick a hyper dog who barks at everything.

And training for the dog is essential. As soon as it's old enough (if it's a puppy), start doing basic training and socialization work. Your dog should be learning commands -- sit, stay, down, etc.

Make proper introductions. Have your dog on a leash and come armed with lots of treats. The cat should be on the other side of the room (either in a cage or loose, depending upon his anxiety level). Work with your dog to have him focus on you -- and not the cat. The more the dog relaxes and doesn't zero in on Fluffy, the more Fluffy will relax. Do several introduction sessions per day to help them get used to each other. Reward all positive behavior. As they get comfortable, you can decrease the distance between them.

Give Fluffy his space. The litter box, sleeping area, and feeding station are places where your kitty needs to feel secure. While in the litter box, Fluffy won't want to be surprised suddenly by even the most playful of puppies. He needs areas that are off-limits to the dog.

Keep everyone safe. Never leave your cat and dog unsupervised until you're 100% sure they get along. Never assume animals will work things out themselves, because the results will be tragic.
