I have a curry brush (the heavy ridged rubber kind) and a cheap plastic curry brush, and a nice dandy brush that I had for my horse when I was a teenager - Ive used them on all three of my dogs since. Scout especially likes the cheap plastic curry. The dandy brush I used also on my cats, really made their fur shine.
In the last year i've bought more stuff for the dog at the tack shop than at the pet store
Must say I haven't used any of those tools on myself, yet
