There are a few cheaper versions of the Furminator out. Of course, now that I'm actually looking for them the only one that comes to mind is the FurBuster. Lol!
The FurBuster--these are available at WalMart and many other places, Petsmart even sold them at one time. This is just the first website I found them on.
I have the Furminator and the FurBuster, and while both work good, I do see a difference in the two. The Furminator does seem to do a slightly better job, but the FurBuster does well too. Really the only reason I bought the Furminator was because I worked at Petsmart at the time and we had the whole grooming kit clearanced out, plus I got my employee discount, so it was a steal.
The Kong ZoomGroom tends to work better on some short-haired breeds, and is quite a bit cheaper at around ~$10. When I worked in a salon for a while, I tried to test both on looooots of breeds. The ZoomGroom seemed to do tooooons better on Greyhounds and other sighthound types, ***some*** Pugs, ***some*** Labs, some Weimaraners, Boxers, a few Huskies..... Really kind of trial and error, as for some breeds it may work great on this Lab but not another, or this Weim but not another, etc. You can use it for bathtime or just as a brush. For dogs with long coats(long as in actual length,
not thickness--Shelties, BCs other than shorthaired, Flat-Coated Retrievers, etc) the ZoomGroom is not a good idea for regular brushing, I would think this would just tangle the hair more than actually brush it. Unless you only went one direction, which isn't exactly how it's intended to be used and then it's more of a massage tool. Lol!
Slicker brushes are best for really thick coated breeds, or longer haired dogs. They aren't really intended for shedding, but more for regular maintenance. Although they do a great job when those breeds are blowing their coats. I use a slicker on Mud just for regular brushing, and for my bf's dog Dixie, who has a similar coat. Slickers are good for Poodle-types and similar coats as well.
