Since Rags had the problem with his annual vaccinations two years ago, I flinch more when he gets his shots than he does. However, they’ve either changed the formulation since then, or the two grams of bute that I now give after he gets his shots helps. He was only moving a little slowly last night when I went out to feed, didn’t have any visible reactions at the injections sites, and had his normal appetite. So it looks as though this year there are no nasty surprises but the vet bill.
