Pico is about a year and a half old and 5 pounds. He is very loving and wants to constantly be with his human. He would probably do best being the only dog as he does get possessive. Unless the other dog doesn't snuggle with you a lot. He loves to curl up on your lap and sleep with you or close to you. If you are doing something, he wants to be up helping. If you are watching tv, he wants to curl up by you and watch too. (Yes, he DOES watch tv) He is housebroken and now asks to go out. Pico still has a lot of puppy in him. He loves playing with his toys and running through the house squeaking them. He loves going for walks and sitting in the sun. He doesn't want to share me with my current 12 year old chihuahua. He snuggles with her, but when I'm around, he definitely wants to be the only one getting attention. He is great with people but needs to get more socialization with other dogs. He is fearful of them at first and thinks he is alot bigger than he is. After a few minutes, he seems to calm down. He loves attention and will be the most loving and loyal companion you could ask for. He needs a loving home where he can feel safe and be your little protector and companion and get all the attention and love he deserves.
