Chewy is 1.5 years old and weighs a tiny 12 pounds. We are completely guessing on the breed and CANNOT say he is hypoallergenic. He is however a very energetic puppy. He is so loving and friendly. He enjoys the company of other dogs and while we have not see him with cats we believe he will be fine. When he first meets you he maybe timid but that wears off about 10 minutes later. He is a dainty little boy but tall. He is housebroken and good on leash.
