Our first babies favorite and longest lasting ball yet and he is fixing to be 7.
Style: Ball, Size: Medium (Pack of 2), Style: Ball, Size: Medium (Pack of 2)
Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.

For the fetch loving doggies. 🎾🦮
Color: Non Squeaky-12 Pack, Size: Medium
Well made tennis balls. Our dog loves playing fetch so these were perfect for her. Will say, if you have a dog that likes to break and chew on any toy then these will break easily with those sharp teeth. My dog just played fetch with them but my parent’s dogs chewed on them.. so theres that.

Color: Squeaky-4 Pack, Size: Medium
My dog absolutely loves these! She's a7 and she plays like a puppy with them. The squeaky lasts a long time and they hold up to a fair amount of play considering she is large. I will buy them again.
