Leo had his second leukaemia vaccine yesterday, he'd had no issue with the first one and was fine last night, chewing my hair and generally being his usual oddball self. This morning I didn't get the usual paws on my face and pleas for going out/food and when he did come down he seemed off, he was walking low to the ground and wagging his tail. I picked him up and he yelped.
He went out and still seemed able to climb the fence but he came straight back to the house which is unusual. DH went to bring him in again so I can keep an eye on him and when he picked him up he hissed (never seen him do that).
Lately he's eaten his dry food but just licked the gravy off his wet food and eaten the top layer, but his bowl was more empty this morning so I thought maybe he ate a lot of it and has an upset stomach? Last time he ate a lot of wet food in one go after eating mostly dry he had the shits a bit after.
Could it be the vaccine or just a bad tummy? Should I take him to the OOO vet?
