Dogs require protective booties when walking on hot pavement or sand to prevent serious injuries to their paw pads. The intense heat from these surfaces can lead to burning and blisters, causing significant discomfort and pain for the animal. When exposed to such conditions, dogs are at risk of overheating, as their bodies struggle to regulate temperature effectively. By using dog booties designed for heat protection, pet owners can safeguard their furry companions from the harmful effects of scorching surfaces, ensuring their walks remain safe and enjoyable.
