She is limping on her back leg and not able...

Hello! I am Dr. Erica, a licensed veterinarian with Just Answer, and I am here to help you! I have been a veterinarian treating dogs and cats for almost 15 years. I will let you know that while this is a forum for veterinary advice, I am not legally permitted to make a diagnosis or write prescriptions through this virtual format. However, I am here to help guide you and your pet toward a resolution to the best of my ability. Please allow me a few minutes to review your question. I may ask a few additional questions to gain understanding and better help you and your pet. I appreciate your patience.

I am sorry to hear that Sugar is having trouble with her leg.  Can you tell me what breed of dog she is?

Aw this poor old girl - it sounds like her leg has been bothering her for a couple of months - can you tell me what medications you have tried?

Is gabapentin the only medication she is on?

Ok; as a single agent, gabapentin is not a great pain medication.  It works best when used in combination with a non-steroidal anti-inflammatory medication (NSAID - something like Rimadyl, Metacam, Galliprant, etc).  Because it sounds like gabapentin is not doing a good job controlling Sugar's pain, I would ask your vet about using it in combination with one of these NSAIDs.  Your vet may recommend running some bloodwork prior to starting her on an NSAID to make sure that her liver and kidneys are healthy, and I would suggest you get this done just to make sure we aren't causing more issues with the meds.  But combination drugs for arthritis are often quite a bit more successful than single agent medicaitons.

Oh good!  In that case of course, the labs may not be necessary.

Hopefully you can get her on a more effective regimen of medications.  Is there anything else I can do for you today?
