Nearly all KOA campgrounds in the U.S. and Canada welcome dogs at tent and RV sites for no additional fee, and many locations also offer dog-friendly cabins for a small pet fee. The most pet-friendly KOAs, like Coloma/St Joseph KOA in Benton Harbor, MI; Tucson Lazydays KOA Resort in Tucson, AZ; and Cape Hatteras KOA in Hatteras, NC go above and beyond, offering private Paw Pens at select RV sites and cabins, pet wash stations, agility equipment in Kamp K9 dog parks and loaner pet kits with bowls, beds and treats.
