While the Shiba Inu does not have to be groomed a lot (he takes care of his own grooming just like a cat), he will still shed heavily twice a year. That is when he gets rid of his undercoat. During this time, your dog will look like he lost a good deal of weight. However, once the hair grows back, he will re-emerge as that huggable and live “stuffed toy” that you have come to know.shiba inu
