My dear sweet Stella Blue woke me this morning coughing, then throwing up, she then could not walk straight, and continued to throw up until it was nothing but yellow spit (??). She refused to eat, and she was freaked out, eyes darting around, nervous. At the time, I did not know if it was neorological (tumor, disease?!?). I rushed her to the vet, but before I could get ready she had thrown up again and peed on herself.
You can imagine my pain today, but I have found that it is probably, HOPEFULLY nothing but an inner ear infection, or something a little different called Canine Vestibular Syndrome.
All pray that that is it, and I hope this helps anyone in my situation.
