My cocker spaniel (see avator) has been sick with a fever and some pain. I took him to the vet who ran a complete tick disease blood test on him and it came back negative. He gave him a shot, gave me some antibiotics and pain pills and told me to get back to him. Well, my dog seemed better the next day, then I sent my daughter out to walk him. She was upset when she came back and said that Rufus could barely walk and cried when he had to climb a small step. He seemed feverish again and laid down and would not eat. When we touched his head or sides he yelped. He was trembling. Gave him pain medications and he was better. He does NOT have an injury though. I'm really afraid he has Lymes or some other tick disease even with his blood test being normal. On the plus side, he is alert and his stool is ok. He eats after he takes his pain pill. I called the Vet again and he said to wait until Monday and then see. So I'm waiting. Does this ring a bell with anybody? I'm really worried about my Ruffy Doo (as we call him). He's a seven year old cocker spaniel who weights 35 lbs. He has been wanting to be near me all the time and it's breaking my heart.
