Our Rat Terrier gets what we assume is leg-pain, as he favors the leg, wimpers & often shivers, leg is very sensitive to touch. We keep him in house except for leased walks, & cannot id any particular incident that would contribute to injury. Any thoughts would be appreciated.
I doubt this is a muscle spasm. I recommend a visit to the vet for a check-up. There caould be many different problems, depending on which leg ( front vs. hind). Good luck, vetcare
