Its not entirely true that they do not moult. Depends entirely on which parent the dog takes after, they can be smooth coated and still shed, they can be medium/curly and still shed but also need clipping or they can be very curly and non moulting like a poodle so will need clipping regularly (as much as every six weeks). This is the problem with a crossbreed, you cannot know what they are going to be like until they are fully grown, even if they are a F1 (first cross between two purebreeds) but if they are crossed back again then you have lost any identity with original breeds.
