I have a 7 Mon. Yellow Lab. He has started his bird dog training. After a session and we got home he jumped off the tail gate (which is normal). I noticed he had a limp on his front right leg. It was pretty bad at first but then started to go away. Everyday it seemed to get better but it is still noticeable. I decided to take him for a short workout after 4 days of no work and after I got him home he rested and then began to limp again. There is nothing between his toes and no noticeable pain when I bend or stretch the leg. His activity is still great and everything seems normal. Today is day 6 since the initial "injury" and he still favors the other leg. It's not bad but noticeable. I was going to give him the weekend off of all training and if the condition does not get better take him to the vet. Am I being overly worried?? Should I take him to the vet now? Need some help.
