I had to reply to this. Not all groomers use cage dryers with a heat setting. I am a mobile groomer with 6 years experience (I did not go to school and am not certified, however one can do this)and no I wasn't a bored housewife when I started. I happen to have a great love for dogs and do very well with them. Being a mobile groomer I do not cage dry, I do hand dry. Where I have worked in the past the dryers for cages did not have heat settings. Some do. Groomers do their best to take care of the dogs. And for everyone's information I have worked at a Pet something and just because they have windows up front doesn't make them the best place to go. Use your own judgement and go by how you comfortable feel. They do not have windows in the back (at least not where I was) so you can't see them drying the dogs anyway. You can bathe a dog in a container, however it is easier just to use a sprayer with a dog shampoo (for ph balance). A hose with no sprayer will take awhile to get all the shampoo out. Dogs should NOT be spayed until they are 6 months of age. Some vets will nueter males as early as 5 months. I think that is a preference thing. I have worked for 2 vets. Also, I do not recommend staring at your dog through a Petsmart window while it is being groomed. If the dog sees you it will get excited and not want to stay still making an accident more likely to happen. As far as I am concerned the lady who started this post is giving advice with no credentials or job related experience, unless I am unaware of them making her the same than those she is accusing.
