My dalmation is 8 years old and he recently injured himself, he has a knot around his shoulder blades. He can't lift his head up more the parallel with the ground and sometimes cripples down when trying to lay his head. He's on tramadol and flamodadine for now...looks to be a sprain cause he can still walk and wag his tail. Any ideas? Temps fine, stools fine, gums are fine, wants to be normal again, but can't bear the pain....keep him on pain meds and rest?
