Hello all!

Little Zoe is almost 12 weeks old and she needs some proper grooming supplies. I went to buy her brush(es) and a comb but there were just too many options, I wasn't sure what would be best. I've read as much as I could on here as far as what people recommend. General consensus seems to place Chris Christensen products as the preferred line. That said, Zoe is just so tiny, a flea comb from the pet store that was $1, is almost the perfect size for her small body. I know she should probably have a comb and a pin brush, but I've also hear about slicker brushes and buttercombs, and have no idea the difference between any of it!
I'm not necessarily in a position to invest in brushes/combs, especially if I'm buying something that'd be too big for her! So, as far as a tiny (2.5 pounds right now) little puppy goes, what should she have?
Thanks!
