5 month old puppy limping on back leg all day today with sudden onset. Walking fine in morning and an hour later limping and will not put weight on it. Conducted an at home test to see if he was in any pain and no yelps when touching/squeezing/inspecting from toes on up the leg.

I am sorry to hear about Buster! I would recommend bringing him in to his veterinarian for an examination. Even if he did not yelp or cry out in pain, if he is limping he is painful. Dogs are very good at hiding their discomfort and not yelping. I would recommend restricting Buster's activity until he is seen to allow the leg to rest in case he has a sprain. No running/rough housing/stairs/jumping on furniture, confine to a small room or crate when not directly supervised, outside only on a leash to stop running. Your vet will examine Buster and may recommend x-ray if they have any concerns about possible developmental problems or fractures, and may prescribe safe pain medication if needed.

    Hi! Thanks for entrusting us with Buster's care today! Lameness can be a sign of a few things that range from a muscle sprain to even a fracture. I recommend that you have him evaluated by your veterinarian so that this can be further assessed which will likely include radiographs. Treatment will be dependent on findings though at the very least pain control medications can be prescribed. Good luck! Hoping for a speedy recovery!
