Even breeds whose fur does not have to be cut or trimmed, such as all shepherd dogs, Golden Retrievers, Border Collie, Bernese Mountain Dogs, etc., will certainly feel more comfortable if they are freed from their thick undercoat in spring. The duration of the hair change will be shortened, the summer will be more bearable and you will surely find less dog hair in your apartment.
Overgrown eyes and ears, felting between the toes are a torture for every dog. Feces and urine in a dense, long and matted coat are not only unattractive but also very unhygienic; not only for the dog!
