Her name is Lucy and she is a 10 year old cocker spaniel. All evening she has been on and off shaking and panting heavily. I gave her water. Wrapped her in a blanket but she can't stop. She vomited earlier and seemed fine after. But ever since she had constantly been wanting to go outside. I let her out earlier and she was fine she just sat in the drive way. My parents refuse to go to a vet. And I'm really concerned for her. What could be wrong?
