Hands down- the Hair Buster comb. Here is their website- http://www.hairbuster.com/ I can’t remember where I ordered mine from- I know it was not the website directly it was a rabbit supply place. I think that you would want the short hair comb- as that is what mine looks like- and the bunny places only sold one type as I believe they only had one original design. I am sure I order other stuff along with the comb- but I can not remember where the heck I got it from.
This comb works awesome- the “rubber inset” on the teeth gently pulls out the loose hair. Work great on my cats too- all short hair. I don’t use it on my long haired dogs ever- but it might work. And it hold a majority of the hair on the comb so you have to pull the hair off as it gets “clogged”- but that means it is not sending all the hair up into the air and making a huge, huge mess like the Furminator and Zoom Groom sometimes can. My bunnies do not care for the Furminator either- the cats like it though.
I love this comb so much that if I found out they were going to stop making them I would buy another 4 to stock up to have in the future- in case I lost one, etc.
