I am a volunteer puppy raiser for a guide & service dog school, and I live where summers routinely have highs in the upper 90's and low 100's. Since my puppies go just about everywhere with me, I need to protect their paws from hot pavement and concrete for several months of the year. The RuffWear Grip Trex boots have been a great product for my need. My puppies over the years have all adapted easily to wearing them, the boots are breathable, they are sturdy, and they wash well in a washing machine. These boots are well-made and I have only needed to buy new ones when I have a pup with different sized feet than the boots I have on hand. You might find cheaper boots elsewhere, but the quality is cheaper, too. Buy RuffWear and you won't need to replace them every couple years.
