How cute can he be? Umi is supposed to be a long-hair Chihuahua mix. We think there may be some Papillon mixed in there…have you seen those ears? Umi is about 5 months old and weighs 7.5 pounds. He has had his first puppy shots and microchip. He will be scheduled for neuter when he is 6 months old. He is doing well at his foster home with other dogs and cats.
