Q. Our dog is eating, drinking normally, but every once in a while will step on his left foot and yelps. Other times will walk and run with no problem.

A. There could be an underlying orthopedic problem in the left front foot (or really anywhere in that leg, or even in the neck). It sounds very intermittent in nature, so he'll likely need a vet exam to try to localize the source of the problem (i.e., which bone, joint, muscle, or tendon it is) and then maybe x-rays to get a better look at the problem.
