Dog owners and their families may welcome a new dog with open arms because they recognize these pets provide unconditional love and can make their human companions smile no matter what else is going on in their lives. However, other dogs may be considerably less enthusiastic about rolling out the proverbial welcome mat to another furry member of the family. In recognition of the potential difficulties of welcoming a new dog into a home where a dog already lives, the Humane Society of the United States and the American Kennel Club offer these suggestions to help dogs get along from the moment they meet.
