I have a Shiba Inu who is a year and 4 mos old. when I got her a little over a year ago, the local pet store owner recommended a slicker brush for her. This is the second time I have had her shed her undercoat, and the slicker seems to be making it worse, not really picking up much hair. should I pick up another grooming tool for her, or is this a typical issue when owning a shiba? Is this a good time to take her in for a de-shed with the groomer, or is there something I can do at home?
