West Paw Design's Boz is a light, bouncy and soft dog ball that’s easy for them to catch in their mouths. Boz dog ball has a durable exterior texture that engages fetch fanatics while the Air Technology gives it a satisfying squish. While human hands can’t typically squish Boz, dogs can compress the ball between their teeth giving them a satisfying endorphin release. Unlike a tennis ball, Boz is durable, squishy and doesn’t contain any toxic glues or lead. Size small fits in a standard ball thrower.
