We’ve gone through a LOT of toy balls here at Retromatti for Quentin, our lovable chihuahua rat terrier mix. But he destroys them all so fast! That is, until we got these – not only are they INCREDIBLY durable, the squeaker lasts forever too! Now all we worry about is losing them when out for a walk or play in the park! I cannot recommend these balls enough. They are the BEST squeaker balls for small dogs – the balls are 2 inches in diameter. And they are the bounciest we have ever had in here! Great for chase play.
