My dog's back legs are weak when standing, uncomfortable, no limp. Why?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 32 lbs

Flash seems to have something bothering him with his back leg/s he is definitely favoring it and seems uncomfortable but is not walking with a limp. Both back legs seem a bit week when he stands up but when he's up he is just fine. He sits like he is trying to stretch his legs. He doesn't seem as energetic as usual but isn't lethargic. I cant see any swelling. Both legs seem to match and he doesn't seem bothered when I touch either leg. He is definitely uncomfortable though.

Hello, sorry to hear about Flash. This could indicate anything from primary orthopedic or even neurologic injury. Common orthopedic injuries include injury to the cranial cruciate ligament or hip dysplasia. Common neurologic injuries include a slipped disk or a narrow lumbosacral joint. Both of these conditions are best diagnosed with a thorough orthopedic and neurologic examinations. In the interim, he should be kept quiet with no running, jumping, or rough housing. Alternatively, pain could also be associated with abdominal discomfort particularly in dogs that have pancreatitis. If Flash develops any vomiting, diarrhea, or loss of appetite then he should be screened for pancreatitis by your veterinarian. Please have Flash seen by his veterinarian this coming week or sooner if he is not wanting to eat, drink, or is acting lethargic. Hope this helps and best of luck.
