Mya is such a sweetie
I can't really advise on her hair, Mika is still so young so I haven't had any grooming issues yet! I do know that I want to leave it long, if you search the grooming section you may find some help there! As for chewing have you tried an anti-chew spray? It does need to be topped up alot to begin with, keep re-spraying a couple of times a day, just spray the places she has already started to chew and of course tell her NO if she attempts to chew and reward and praise her if she backs away without chewing! Make sure she always has fresh chews/toys when she is left alone, rotate them so she always has a different selection each time you leave her! I hope this helps, but you could also use the search tool to find old posts on the subject! Good Luck!!!
