Little Cooper is 8lbs, and was dumped, we suspect, with 2 other dogs found roaming, and he exhibited extreme fear aggression, upon intake. Now with a foster who is helping him adjust to the big changes he has been going through, he is coming around, with her. If you are patient and have experience with small dogs who can be terrified with new people, which can cause him to nip at you, then this could work. He is in foster care with several other small to medium dogs and is around cats and is fine with them. It took him a week or so to fully trust his foster, but he will still nip at newcomers, if they try to interact. But if they just ignore him a few days he warms up. He would love to be held by his PERSON, all day, per his current foster mama. We believe he will do well in the company of other dogs. An older child might be okay if they are not loud and respect his boundaries. At 8lbs, he is now neutered and current on vaccines and flea/tick and heartwrom prevention.
