Big Henry, my 10 year old Airedale, went to get his booster shot for lymes desease on Friday. He was fine on Sat. But come Sunday he was panting endlessly and was very lethargic. He only drank water and he immediatly barfed that up. I cannot get him to eat at all. Today he was more active and his breathing was less labored, but he still won't eat. Today he drank gallons of water but this time he kept it down. I force fed him some rice and boiled ground beef tonight but only got 4 spoonfuls down him before he just refused to eat. He's 105 lbs so if he says no it's no. I don't trust the vet now as I think they may have may a mistake. Could this be a bad reaction to the booster? Any vets on the board?
