Can dogs pull muscles? I feel like everytime Gus comes back from my parents house he walks a bit stiff. They have all hardwood floors and he slides on them constantly chasing the other dog. Gus had his knees and hips checked in November and they were great and he is only a year old. Do you guys think I should take him to the vet again? He isn't limping... he just walks with a stiffness especially after he has been sleeping and slightly bobs his head. He hasn't stopped trying to play with Boomer and he still jumps on the bed every chance he gets???!!!
