A common misconception is that the Collie needs daily brushing or frequent bathing. The amount of coat care is dependent upon the amount of coat a dog may have and the time of year. Rough Collies in full coat should be brushed once a week or every two weeks. A dog that is out of coat or in summer coat is going to need less grooming. Spayed females and males shed once a year. Intact females shed according to their heat cycle. The smooth coated variety will require less brushing and maintenance, but both varieties do shed. Collies are a very clean breed and are noted for not having a doggie odor frequently found with some other breeds. It is recommended that the puppy or adult dog receive a Microchip implant or a tattoo for future identification purposes.
