My puppy is still too young to get his rabies but has his other vaccines. Is he still able to come to the campground?

May depend on who is at the booth

Yes, as long as he has the others should be good enough

No sorry you need to have proof that your dog has the rabies shot for legal reasons

I don't think so. I know when I came, they made me show proof my pup has her current rabies vaccine. Congrats on the new puppy!
