Simon just got his booster today...and he hasn't been himself since...I can not sleep and he doesn't want to get up and he whines or yelps when I touch him...I am so scared that something is going to happen to him...I had no idea that these little babies could have an allergic reaction to the dhlpp shot.....there are no after hour clinics here and I have had no sleep, and don't know what to do...I guess I will just tough it out until the Vet. office opens...
