Some dryers have a heat setting. The groomer needs to check the heat, if it's too hot, they need to turn the heat off. If they're cage drying, they should NOT turn on any heat, it gets too hot for the dog. The high velocity dryer that was in our mobile grooming van had no heat, it blew room temp. When I blow dry my guys w/a hair dryer, I use a cool setting, even the warm can get too warm.
This is from that link, they even show pics of the poor dog
: A spaniel was virtually cooked to death in a home-made drying cage after her owner dropped her at a dog groomer.
The next time Maureece Sarell saw her pet Trudie, the animal was critically ill at a vet’s. A court heard the seven-year-old had to be put down after suffering internal bleeding, blistered skin and dehydration.
Magistrates were told the golden cocker spaniel spent 20 minutes in groomer Jo Taylor’s contraption – made from a tarpaulin-covered steel cage with a heater attached.
You'd be surprised how many groomers get bit, by cats & dogs. If you get bit by a cat (since they have very sharp teeth) & it severs a nerve, you can't use for your hand! There's some dogs that turn into kujo when they're put in a cage. If the owner doesn't tell you this, you get bit when you take him out of the cage. That happened to a girl in our grooming class, she got bit by a cage fright dog & she was bleeding a lot. I've had to muzzle some dogs bc they hate to have their nails clipped & they tried to bite me. Some dogs hate the high velocity blow dryer & try to bite me & the dryer. I've learned to watch their body language & they'll let you know they'll bite by showing you their teeth.
For that groomer to come right out & say those things is rude. I never charged anybody more bc the dog tried to bite loll. It's part of the job.
