In Sequoia National Park, pets are generally permitted on paved roads, in campgrounds, and in picnic areas. However, they are not allowed on trails. Since this is a road cycling route, your dog would be allowed if kept on a leash, but always verify current park regulations on the official NPS website before bringing your pet.
The road surface is generally well-paved and considered excellent for cycling. However, be aware that due to ongoing repairs from storm damage, there can be road construction, potential delays, and one-lane traffic control.
