These drying cages/crates should be banned everywhere. I have only brought Pebbles to a groomer once, when she was about 4 months old. The groomer is located nearby and had good reviews online so I called up and asked if Pebbles could come in for a short appointment to meet her and get her nails trimmed. While there I noticed a number of things that made me uneasy so I never went back again.
Among other things she had 2 little dogs, they looked like yorkie mixes, in a drying crate. They were panting due to the heat. I would never, ever want Pebbles placed in such a thing. Since then I have been grooming her myself - I asked the nurse at the vets office to check if I'm cutting her nails properly and the rest of her grooming is pretty easy, apart from her face. I'm not very good at cutting hair so her face doesn't look as neat as some yorkies but at least I know she's safe.
I found another article about a dog in a drying cage.....it made me cry....this poor dog didn't survive. I'll place the link here but it's upsetting
