I pay 18.00
FYI You have to give 2 shots the first time about a week apart I believe.
I paid like 45 bucks but it was his first shot.
You get the second one after 3-4 weeks.
I hope I can get it for 18 bucks next time.
Do they sell it anywhere so you can do it yourself? I hate to pay for a vet visit just to get one little shot.
