I bought my boar brush at a beauty supply store. (for humans) I bought my pin/slicker brush here
http://www.chrissystems.com/ I also love their shampoo and conditioner (Day to Day line) and their Ice On Ice conditioning spray is awesome. I spray her before I brush her all the time!!! It's awesome stuff it works wonders but it depends on your dogs hair type because on Adina it works great but when I used it on Joy her coat looked oily. It took me a while to find a shampoo and conditioner to suit Joy. i use Coat Handlers on her!!!!
