I got my dog her 1st Cytopoint shot last August. She had no bad reaction. I got her another one in November. Within an hour she couldn't walk. She was vomiting and her eyes were going in different directions. My Vet diagnosed her with Vestibular Disorder. There is no doubt in my mind that it was caused from this shot. My Vet took x-rays and blood work. Her red cell count was low and it was fine 2 months previously. It's been a long 2 months of TLC and she still vomits sometimes and won't eat. I couldn't even give her her antibiotics and anti fungal pills [ which she needed] for over a month because of the vomiting. Zoetis needs to be held accountable for this.
