OOH! Another hot weather tip for dogs, is get a "ShedMonster" comb, It's sort of like a furminator, sort of, but, a Shedmonster is only $15 at walmart. (the long hair version, shows a cat with a golden retriever on the box, but does not say "long hair version" for some reason?). Oddly, the short hair version of ShedMonster, which IS labelled "short hair" version, which shows a black lab and a cat on the box, costs a bit more at $19. (seems it'd be other way around). I hear these don't work great on short hair animals, though. One can also buy a "SHEDMONSTER" online, too, like on Amazon.com. Really thins out a dog's fur, and removes all that undercoat which probably makes your dog stay TOO hot. I got an entire bagfull of undercoat off of my dog on first time i used it. Even running my hands through Buddy's fur, it feels entirely different now, so much lighter and way less fur now. He looks great, very shiney. Thinned out his fairly massive "skirt" very very much, too, so he doesn't look so funky there now with all fuzzy-looking, cottony-stuffing poking all out through his topcoat, that fuzzy stuff is gone now. YAY!! I'd think this HAS TO help a dog be a bit cooler, if his undercoat is mostly gone, it must feel like having a sweater taken off,. especially for a dark-haired dog whose black fur absorbs and holds the heat.
