Hi David...thanks for your question. I'm sorry to hear that Sassy is not feeling well.

This is a tough one to answer without actually examining Sassy but I can give you a few ideas.

The most common reason to see the symptoms that you are describing is some type of pain. Unfortunately in little dogs like this, back pain is quite common. It can sometimes be hard to diagnose back pain but an experienced vet should be able to tell you if she is painful.

If she is, then some anti-inflammatory medication should help. Unfortunately there really isn't anything I can recommend for you to give her without seeing her as some anti-inflammatory meds can be dangerous in certain situations.

The fact that she is not eating has me concerned as well. This is often a sign of pain or discomfort.

There are other possibilities. She could possibly have pancreatitis which is a serious problem that causes pain in the abdomen. Usually dogs with pancreatitis will have vomiting, but not always.

If she is not spayed then I would be concerned about an infection in her uterus. This is most common a couple of months after a heat cycle.

It does sound like a vet visit is in store.

I hope she does ok!

Dr. Marie.

You're very welcome. The shaking of the back legs makes me even more suspicious of a back problem David. The best thing I can recommend tonight is to keep her as quiet as possible and not encourage any jumping or going up or down stairs.

Your vet will do a good thorough exam and will likely prescribe some medication for pain.

I really hope she is ok!
