Q. My dog was playing fech and started limping and walking on 3 legs some times he walks on all 4 legs. Do I need to go to a vet?

A. Yes I would recommend a vet visit because he is having intermittent (off and on) limping it could mean he has a muscle sprain or a torn ligament in the knee. They can look the same so it is important to have your vet examine and perform a lameness exam to tell which is more likely so that proper treatment is implemented to help avoid further injury to that leg and also the other leg he most definitely is bearing more weight on to take the pressure off the injured one.
