Why is my lab limping, low energy, and not putting weight on her leg?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Female | spayed | 5 years and 10 months old | 100.3 lbs

My lab is limping on the right side (she is being examined on Friday May 4/2018 by a vet in our area) she's still wagging her tail, eating and drinking. She is not very interested in playing and her energy is low. She is clearly uncomfortable. This limping has gotten worse in the past 24 hours. We notice intermittent limping at the beginning of the year. Now she's not putting much weight on the leg. We were told by our regular vet she is just over weight. But I feel it's something else.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Lameness can be caused by a number of things. Unfortunately, in this breed, ACL injuries are common and are typically due to degenerative changes with the ligament (if this is a back leg lameness). Also, if this is an ACL injury, there is a > 50% chance that the opposite leg will be affected by the same problem down the road. On the examination with the veterinarian, they will check her knee joint and see if there is an instability called a cranial drawer or a tibial thrust. Both of these manipulations help confirm the suspicion of an ACL injury. Most of the time, an ACL injury requires surgical correction to fix. This can be discussed further with your veterinarian once diagnosed. This may not be an ACL injury and may be osteoarthritis or hip dysplasia causing discomfort. I would recommend x-rays of the affected leg. If this is a front leg, there are other possibilities such as arthritis, a bone fracture, infection, ligament injury, elbow dysplasia, etc. I would definitely get Bliss on a joint supplement along with omega 3 fish oil. I typically recommend Dasuquin and Welactin for supplements, which can be found online quite easily. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please remember to rate this answer as helpful or not. Thank you!
