Hmmmm....I am unclear. Do you mean you have never had rabies shots for your puppy? Or, any innoculations? That sounds very irresponsible to me. Are you sure you aren't just confused?

As to the bark park...if your dog is not up-to-date on its shots, then, you shouldn't bring him/her to the park. It isn't fair to those of us that do keep our puppies up-to-date. You don't need to bring anything else, just yourself. The park provides poop bags.

If your dog is aggressive, it shouldn't be brought to the park. Why risk your dog's health, or another's, by doing so?
