Apologies if this has already been addressed. I did do a search and it seems like the Chris Christiansen products are much-liked. But there are many choices on the site (and these are quite pricey once you get the wood handle too).
My doodle is curly fleeece. His legs are almost always wiggley strings with no matts, but his neck, butt and belly/pits matt very easily. I have kept him pretty short as a result, but am considering trying to go long until May when it warms up a lot.
I have a red, small Les Pooches brush... I have used human combs on him, but know this is not the best way to go.
Yes, I thought the rotating tines would be wonderful and gentle but it is just not right for him. The steel comb I have was given to me by the groomer but you can get them places. It is not fancy and doesn't have a handle. Sometimes I do wish it had some sort of covering because the edges dig into my palm.
