Hi, earlier today my 2 year old minpin was at the vet for a booster shot (since we live by the woods and ticks are more common). He was fine earlier before the vet but he seems sluggish and is shaking alittle now that several hours has passed since he got it. My sister is holding him in a blanket so he stays warm but when he does walk you can tell it isnt a normal walk and also he didnt eat supper tonight. I called the vet and they said its normal, as long as his throat or ears are not swelling he should be just fine. I tried to google the symptoms but couldnt find much, so just making sure that its "normal" for such a small dog to be sick after the vaccination?
