I actually have a 4 year old PitBull, so its really important for me know what the pet restrictions are when we go camping. Most of the campgrounds that are near the coast will be closed soon though because of the freezing ice, but one of my favorite campgrounds is Lake George Escape. They don't allow pets on the rentals but if you take your own RV there are no restrictions. A few of the other campgrounds that we've gone to with Toby are Alps Family Campgrounds, Camp Chautauqua, and Frost Ridge Campground (another favorite, but they close for Winter also). They are pet friendly and have pet walking areas. Plus there's no FEE! It makes no sense to pay a fee to bring Toby when I'm the one watching him and cleaning up after him, dont you agree?
Have a fun trip!
