Do Maine Coon Cats Like Dogs?
Most Maine Coons are more doglike than catlike and will make friends with your canine, but we always recommend introducing pets to each other very slowly, and always supervise the interaction until you can be sure that your pets get along and won't hurt each other. If your dog has a high prey drive and likes to hunt small animals, it may see your Maine Coon kitten as something that can be hunted. In this situation, keep your dog and cat separated.
Maine Coons will protect themselves if they feel threatened, and most dogs will back off when they hear the deep throat warning growl from your Maine Coon.
I have heard several horror stories of cats being mauled by dogs so PLEASE do not ever assume that your cat and dog will be best friends and get along.
