I am so sorry to hear about Wrangler! It sounds like he definitely needs to visit a vet for an examination. There are some conditions we see in young dogs that can cause pain, such as panosteitis, hypertrophic osteodystrophy, and osteochondrosis dissecans http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=3238 . We maight also worry about things like infections of the joints or tick borne disease which can cause joint pain and overall malaise. The vet can do a thorough physical examination and may recommend testing such as x-ray or bloodwork based on their exam findings. Best of luck to you and Wrangler!
