Thank you for your patience. I'm sorry to hear that Lola seems to have injured one of her hind limbs. As you can imagine, there are a number of things that could be going on in this leg. If this lameness just began 'all of a sudden', then it is most likely to be a ligamentous injury such as a torn cranial (aka anterior) cruciate ligament - in which case surgery may well be necessary. Other options include anything from a full fracture, incomplete hairline fracture or just the onset of arthritis and degenerative joint disease, which less likely given your girl's age - 4 years.
I really would encourage a full Veterinary physical exam in order to try and pinpoint the exact cause of her lameness and your Vet may even encourage you to get several xrays taken which would definitely help identify the problem. Given her breed, age and how this happened, I am most concerned this could be a cruciate ligament problem. If your vet suspects this, he or she may need to sedate your girl, have a feel of the injured hind leg and take a couple of xrays to get an exact diagnosis.
Thankfully there are a number of treatments you could try for your girl for any of the above potential problems. These range from Pentosan shots which help stimulate cartilage formation, to nonsteroidal anti-inflammatory drugs, to opioid based drugs and even all the supplements including glucosamine and chondroitin etc. So don't panic - there are plenty of options available depending on the cause of her lameness. Unfortunately there aren't any drugs you can give from home that will help relieve pain for you girl that are safe for her. Don't be tempted to try her with any of these, as they typically do more harm than good.
Do try and see your vet tomorrow morning if you can, if your girl still seems to be painful when she is fully weight bearing on the leg. In the meantime, please try and keep her as quiet as possible with only careful leash walking outside to go to the toilet. Hopefully it is just a bit of a muscular strain that will improve with some veterinary prescribed anti inflammatories. I hope all of the above makes sense?
