I use three different brushes, a furminator, a furminator brand slicker brush and a comb. I usually brush him once or twice a week and that seems to work for us, his fur his thin and silky. I use the comb on his ear floofies and butt puffs, really helps to keep mats from forming!
Another thing I'd highly recommend if you're not already is also giving fish and coconut(extra virgin unrefined) oil supplements. They do amazing things for their coat... Like I said my dogs is soft and silky and SO shiny, they have other great health benefits too.
I don't plan on using a groomer since I can groom him easily enough myself but I might like once a year or something.
