We rehomed a dog a week ago - he’s a JR / Border Terrier cross so quite active!
Yesterday we noticed him limping on one of his back legs - we can't see anything wrong with it, he let's us touch it without complaint and is his usual happy self (wants to walk, eager to run, eating, etc).
Is this a muscle strain because he's now getting two walks a day (he hadn't been walked for weeks with his former owner ??).
Any thoughts or suggestions would be welcomed!
