For Westies I recommend the owner to keep up with the brushing to keep the coat knot free and healthy and come in for a westie clip about once every 8 weeks, thats when it'll start to grow out and look a bit dowdy. If your not into brushing take your dog in more reguarly to make sure matts don't form in the skirt, pants or head. Also if you can't afford to get your dog clipped ever 4 weeks or so because you don't want to brush, you can book into your groomers for just a bath and brush out to get rid of loose and dead hair (it'll also keep your Westie whiter for longer

) and it wont cost as much as a clip. Traditional grooming procedure is a handstrip and some places will still do that (you'll pay thorough the nose), but its much more common now to do a clipper trim on these dogs, it is alot less stressful on the dog and the pattern lines followed when grooming Westies is the same, whether clipper or handstrip. As the owner, its all up to you..
