Does anyone know how much a dog creche charges, is it per hour, per half day or per day. Also how much is it.

do you mean the ones that look after your non entered dogs at champ shows??

How does that work, and what do they charge.

If you mean day care for dogs it varies. My local one charges £4 an hour but gives small discounts for people who bring their dog regulary. The boarding kennels will take dogs in for the day for £5 but they are just in a kennel on your own. If you google around you'll find some centres post their prices on their websites. It will vary depending on what area of the country you're in.
