I had a thread in here a while back about my "sluggish" pup. He's a 9 month old lab and just recently started doing everything at a slow pace I mean he's 9 months and should be bouncing off the walls.. I had him vet checked for everything (I.e. worms, hips, eyes, allergys etc) and everything checked out perfectly so I switched his puppy food to another brand to see if that would help but still no luck. Any ideas on what to try next???
