My corgi is going to be 11 this year. She started having limping with her right leg and now it seems to be both. When she walks outside she actually drags her right paw. It turns black from the ground. 2 days ago she started to fall on her back legs. They slip out from under her on tile floors so I have laid blankets down for her. She is spunky and doesn't seem to be in any pain. I rub her hips and stretch her legs and it doesn't bother her. I am calling the vet on Mon for an appt. Could this be hip dysplasia?
I doubt it, it sounds more like neurological or a pinched nerve. It could be arthritis in the back causing some problems. I would definitely see your vet, and consider a specialist. Alot times when the dog starts turning its foot over and not noticing it is neurological. With long backs, that is a recipe for all kinds of spinal problems. Even pinched nerves and spinal arthritis.
Ask your vet about degenerative myelopathy, it is a common Pembroke spinal issue that causes degeneration column part way back. Happens mostly in senior dogs and Pembrokes are one of the most affected breeds for this issue. It is also referred to DM. If your dog does have DM, I highly encourage you to allow a spinal sample be taken when she gets to the point of crossing over the rainbow bridge as this disease is still being researched and while we have found the genetic markers for it, we have not found it's triggers. I will try to find some links to send you regarding DM.
I hope TP doesn't take this link down as it is very helpful and up to the minute from a lecture recently given by the official researcher on DM. It is from another online corgi community but the information to this post is invaluable for anyone wanting to know more until it is posted elsewhere in a non-community setting.
