Welcome! I am Dr. Altman, a licensed veterinarian and happy to answer your questions today.
I am so very sorry to hear about your little one. My primary concern is an injury to the back back, not necessarily doing something like jumping off the furniture and crying out, they can be walking around the house and have a disc herniation because of their anatomy.
Here is more information on this condition:
Ideal is to have your veterinarian evaluate your dog to definitively diagnose the problem and start on appropriate medication to control the discomfort. Until you are able to do this please restrict activity (which often they are already doing themselves but that means no steps/ stairs and only carrying to go potty) and rotating warm and cool compresses on the back in ten minute intervals to reduce pain and increase blood flow.
You can also do light circular massage up and down the back to stimulate blood flow if this is not too painful and will allow it.
To pick your dog up please use one hand between front legs
and then scooping behind back legs to avoid pressure in the middle of the back and the crying when picked up. I have actually trained my little dogs to put their front legs on my forearm to minimize pressure on their backs and the associated discomfort.
I do not suspect hip dysplasia from your description but more of a back injury of some kind. Restriction is key but again if there is no improvement please have her seen by your veterinarian to diagnose the problem and begin appropriate therapy. Please let your veterinarian know you have administered aspirin because it will effect what they will prescribe for Lexi.
Please let me know if you have any additional questions I can assist with. I hope you are able to get your little one comfortable soon, truly.
