I just got back from my hunting trip and I noticed during the trip Max started limping on his left front leg. The weird thing is that it just comes and goes. Yesterday during training I threw a mark for him and he ran out there but when he came to a stop I noticed the limp started again. I stopped what we where doing and took him home and within 30 minutes it was gone. I'm thinking he might have strained/sprained something but I'm starting to worry a ligament injury. What do you guys think?
