My little Girls name is Mochi too! Welcome to YT!
As far as grooming goes, Mochi's hair grows verrrryyyy slow! and shes still a baby (7months on 11/7) so ive only had her professionaly groomed once. I HATED it! they SHAVED her face, including her topnot with i told them at least 3 times NOT to cut!
Ive decided as of now ill do the large majority of her grooming, maybe getting her professionally groom once every year or two years.
Its just really expensive, plus no one will give her as much TLC as i will
I bathe her 2 times a week (Saturday and Tuesday usually), and before we go to the Vet. Trim her hair as needed (not often). her nails i do get trimmed professionally though (one day i might start doing it, it just scares the hell out of me). and brush her every day or every other day.
