He was fine one day, the next day he whined if you touched his side or if he had to jump up to the car and had a fever of 103 (I found out that's a fever for a dog). He was lethargic and wouldn't eat. I rushed him to the vet who ran tick disease tests and it all came back normal, but he knows that dog is sick. He gave him a shot and cephelgem pills (something like that). The dog perked up all day today then I sent Nicole out to walk him and she came in all upset, saying he was whining and could barely get up a very short step. He started trembling (like he had when he first got sick) and I put a cover over the dog and called the Vet, but it's too late and the emergency vet is $89 just to walk in the door, not including the tests. Tomorrow the vet will be in again so I have to wait. I'm so worried. He didn't eat again and is just laying around. If you touch his head or sides, he whines. If he doesn't have a tick disease, what else could it be??? Any ideas? He is a seven year old cocker spaniel (see avator). I am actually in tears. I really love my pets. Do these symptoms ring a bell? On the plus side, he has no diarrhea and is alert. Thanks for any feedback.
