We like the Pet Neat brush! https://www.amazon.com/dp/B01M5DS0Z7/ref=cm_sw_r_cp_api_glt_i_GQ6DXFDVAE0FHNX7QD05
This would be a cheaper alternative too, if you can't afford the furminator & have amazon in your area!
I have a slicker brush that retracts. Picks up a lot of hair and is easy to clean. Looks like this one: https://www.amazon.com/dp/B00ZGPI3OY/ref=cm_sw_r_cp_api_i_6-drDbQSGRM87
My Shiba looooooves getting petdowns when I wear deshedding gloves like these Https://www.amazon.com/dp/B078PJRWNS/ref=cm_sw_r_cp_api_i_4.drDbDZRSASM
I also have amazon’s knockoff of the furminator, but I’ve used it more on my carpet to get out fur the my old vacuum couldn’t pull than I have on my Shiba. https://www.amazon.com/dp/B01M5DS0Z7/ref=cm_sw_r_cp_api_i_GberDb8VH8NMN
