i just got the lyme disease vaccination for my puppy today.. probably about 4 hours ago and he's acting strange.... he's never had any reaction to any other vaccination... but with this one his leg swelled up.. and it must be painful that i can't even touch it without him whining... he can't even walk on it..

i read something about feeding dog children's benadryl.. i don't know if i should do that..

PLEASE HELP ASAP!!

i'm so worried about my puppy =[
