Agreed. Besides the horrific aesthetic effect this will create, if you shave your dog he will loose his natural insulation against the heat.Like everyone said, no way! The undercoat works like an a/c in summer and heater in winter by holding the air close to the body. The dog will actually get hotter plus be at risk for sunburn.
And you should never shave a double coated breed! In many cases the hair NEVER grows back normally. It should only be done in necessary veterinary cases.
Taking my dogs swimming gets alot of the loose hair out. And brushing outside.
But buying a good vacuum is good too
