A dog dryer? What madness is this? What happened to hair dryers? Dogs don't need grooming and shampooing just a brushing. If you feed them quality foods they have a nice coat and don't smell. I'd never trust anyone with my two dogs.
I saw a Judge Judy episode once where the groomers glued a dog's ear back on.
I think the dog dryers were implemented as as way to keep down labor costs.
I disagree that dogs don't need grooming. First, every dog needs a bath at the very least, every now and again. Second, certain breeds require more or less grooming than others. Third, depending on the nature of the dog's activities and lifestyle they may need more grooming and bathing than others. A family farm dog is likely to need alot more due to spending alot of their time outside and in the dirt, mud, and cow shit.
