My 2-year-old Yorkshire Terrier really hates to be groomed, and with the amount of hair Yorkies have, this is not good. To my knowledge, he hasn't had a bad past with groomers, unless it happened before we adopted him at 6 weeks. When I try to comb him with a wide-tooth comb, he will bite the comb, squirm, and I am unable to finish combing him. I am unable to obtain the supplies to groom him properly, so I take him to a groomer about once a month. I would like him to behave for the groomers, but am unsure how to "train" him to do this.
How can I train my dog to behave during grooming?
