My pup was playing with my cat downstairs and came back up with a limp, I'm not sure what happened but he can't put any pressure on his front left leg. It's not broken.. I tried to massage it to see where the pain was and it was a little sensitive on the elbow and top joint.. The vets have already given me an estimate of about 250$ for x-rays and such.. Should I wait it out and see if it gets better? I'm tight with money at the moment.. I was also considering better k9 aspirin for him... Any thoughts?
