I swear my girl is part cow, she loves to eat grass, nice long fresh grass is her drug of choice. LOL. Nipping lightly...hmmm...she can be playing with you and if it were me I would let her know that grooming time is not play time, its something to be enjoyed and always reward her for during and after. I started Mooshi slowly but every single day I touched her and brushed her everywhere! One sessions I would touch her feet and say the word feet and reward, then tummy and say the word tummy and reward, ears, tails etc, etc. make it a nice and fun game. Both my dogs will stand stock still to be groomed because I didn't take any crap and I made it enjoyable for her. As for wagging tails, some days you get them, some days you don't. Mooshi gives hello nips, she nips your bum when you come home if she is very happy to see you! You have to keep in mind TM's, unlike a lot of other breeds, don't feel like they need us, its in their nature, in their genes, they were bred to be independent and to stand alone so don't be offended if your girl isn't a love bug, its frustrating but completely normal.
