My dog is always tired. If you play with him he will play back but after about 5 minutes, he goes underneath the coffe table and falls asleep. He is ony 1 yrs old. HELP!!!

A 1 year Westie puppy is a dynamo of non-stop energy. I truly believe that can't be normal behaviour for a Westie. Please take your puppy to a reputable veterinarian soon. Thanks.
