I won't comment on the way other groomers work, but I will tell you the way I do. When you call for information I will tell you the price your breed starts at and what it includes. For instance Poodles- Toy and Mini start at $35 and includes bath, ear cleaning, nail clipping, anal gland expressing, blow drying and clipping. If you come in and it is going to be more because the dog is totally matted or you are trying to pass a collie off as a sheltie then I'll tell you before you leave the dog. I throughly go over what you want done until I have a clear idea of how you want the dog groomed. The exception is if it has to be stripped because of mats, not much choice there. All my dogs are blow dried on the table, I don't do any crate drying. I only have one or two dogs here at a time and I only keep them for about 2 hours. Because I am a small shop you are dealing directly with me, I am the owner/groomer/receptionist/groundskeeper/secretary. The downside is sometimes you have to wait for an appointment.
When you call a shop ask questions, do you crate or blow dry? What is the starting price? How high can it go? What does it include? How long will he have to stay? If you have an older dog I would suggest you ask if he could be done straight through and then pick him up on time so there is a minium of stress. There are lots of things owners can do to make grooming a good experience. I love what I do, I can't imagine doing anything else.
