Peanut is about 3-1/2 years old. We rescued him from the Lawrenceburg, TN Animal Shelter about 2 years ago. He is extremely loving. We had a female 3 year old Jack Russell Terrier when we rescued him. They get along fine. We then obtained a female Chihuahua who is about 7-1/2 yrs old. Peanut has since become quite food aggressive and aggressive towards both females. He has also begun peeing and pooping, inconsistently. He will go on pee pads and is also walked often. We believe he may be happier as an only pet, but he should not be left alone too long.
