This is from the website of a boarding kennel who serves the Didim area:
The pricing structure is basic, with a standard charge of 15 Turkish Lira per day (which includes a dry food diet and a bone once a week), for all dogs up to approximately 30kg.
Very large dogs over 30kg will be charged at 20 Lira per day.
Special arrangements can be made for any dog with special dietary needs.
A discount will be given for 3 or more dogs from the same household and special rates can be given for stays of 1 month or more or for exceptionally small dogs.
I think this is the average price for this area. The dogs get 2 long walks every day.
