The natural rubber dog balls from 4BF are made with the help of Grupo 201 Oficial, a renowned rubber maker in Mexico. They have been sustainably sourcing rubber from local hevea trees for over 70 years and even provide the balls for some pro-level sports in Latin America.

4BF stood out to us for their non-toxic, additive-free approach to dog toys. The bouncy balls are a safer choice than some other plastic toys that aren’t always the best for pets—and they pack in plenty of fun playing potential, too. The ball and ball-and-rope toy are both fillable, so you can pop a snack inside to keep a pup happily engaged. And when a ball is finally ready to retire after lots of catching, chasing, bouncing, and chewing, it’s biodegradable.
