My pup turns 4 next month. She started having a problem with a slight limp in her front leg. When she stands up after lying down she limps for a few minutes and then seems fine. We tried cutting back her activity (which has made her gain a few lbs.) and put her on a pain/anti-inflammatory for a month. When she takes the meds, I see no issues. When she doesn't take them she starts limping again. They thought a soft tissue injury. My vet has referred us to a specialist vet for their ortho dept. Here's the rub: my mother had a boxer who had a stroke, she took her there for a visit and they did a million tests which cost a lot of money and still didn't find an answer. So now that's in my head. My girl really doesn't like the vet's office to begin with (she doesn't like being forced this way and that)-so I know any tests will be traumatic for her as well. If this were your dog, would you just continue to medicate her or pursue finding out what the issue really is?
