Welcome to YT!
You will find out lots of info here.
I give Jackson a bath weekly (sometimes once every 2 weeks). I use Minksheen (order it online) and BioGroom.
Wet food being bad for teeth is just a myth... kibble doesn't really help keep tarter away any more than a cracker or a chip keeps our teeth clean. Most vets will advise brushing, dentals, etc to upkeep with their teeth. I brush once a week and use Petzlife (but I probably should be brushing his teeth every day).
I feed Orijen and Acana kibble, both made by the same company (Champion) and mix in some wet food as well.
Good luck, welcome to YT.
