Last Tuesday I took Pooh Bear to the vet to get his nails and anal glands done. While there I told them that he has been shaking his head all the time. They checked his ears and did a swab test of some stuff from his ear. It turned out to be a bacterial infection in his ears. They gave me some stuff to clean his ears, antibiotic ear drops and Cephelexin 500 mil. antibiotic pills. He has thrown up 3 times since being on this medication. I'm calling the vet today. Just wondered if anyone else's baby took this and had a sick stomach with it?
