Pet prayers needed

I'm no vet but I'd wager the shaking is unrelated to the cyst. Cysts are very common on dogs an often mean nothing. The Shaking could be a lot of things. But I do know (from having a pomeranian mix) that small breeds are more prone to tremors, epilepsy and other neurological problems. Its worth asking the vet about that as well. Sometimes it can be due to them eating the wrong thing so careful with the spoiling, I'd talk to your vet about the shaking though.

Sending the positive thoughts your way.
