Pets are not particularly welcome at national parks. In Yosemite, pets are not allowed on unpaved trails or in buildings; they must be leashed at all times and may never be left alone. Pets are permitted in all campgrounds except Camp 4 Walk-In, Tamarack Flat, and Porcupine Flat. There's a dog kennel (tel. 209/372-8348), open daily from 8am to 4:30pm in the summer, at the stable in Yosemite Valley. Dogs must be at least 6 months old and weigh over 20 pounds (or under 20 lb. in a dog carrier); a license and proof of current shots must be faxed over beforehand. The fee is $9.50 per day; call for reservations.
