allow me for a moment to hop up on this here soap box an preach to ya'll canine owners for a spell.
when you walk your dog(s) in lets say May, June, July, Aug, Sept in arizona, how come you dont walk them in your bare feet?

um yeah...the pavement can reach temps of 100 to 120 and blacktop is even hotter.
just from my own experience; a petsitter took my dog out for a run one summer. my dogs paws (bloody, raw, burned, pink) took several weeks to heal and he was in a lot of pain.
another example-a friend was in an auto accident in which her vehicle rolled and the scared dog jumped out of the window, in summer, out onto the blacktop. this dog had to have all paws bandaged for months as well as be administered meds and antibiotics.

soooo, if i see you darling daytime dog walkers, i dont hesitate to inform you kindly "your dog's paws are burning."
if you ignore me or get irate with me about my kind advice, i happen to know of a certain sherriff joe and a posse who love to bust folks for animal cruelty. yes, i am that much of an animal rights person that i will make that call.
please consider how hot the pavment is for them. yes, they have pads but so do we. so try it barefoot sometime. i dare ya.
