Absolutely a great dog toy for extremely aggressive chewers! I have a pig pitbull that loves to chew! He has chewed through every toy I have ever bought pretty much right after I give it to him. This thing is durable he hasn’t made a hole or a tear in it yet and he hasn’t made went to town on it when I first gave it to him! I’m impressed!

Kong Works Well...

Size: Medium

Our German shepherd chews every ball we've ever purchased. The other balls are easier to throw for this 75yr old lady. But this Kong ball will out live any other ball I've ever gotten him. A tennis ball doesn't last an hour. Some other name brands takes him a full day to chew up. So far he's tried but gets nowhere with his new Kong. I seriously believe he just might not be able to chew this one up. Thanks Kong. I got the medium and it's a large ball.

Unpredictable bounces

Size: Small, Size: Small

My 3-year old Cavapoo loves these little toys, although I haven’t given them to her all at once. Typically, she is able to chew a little hole in anything with a squeaker within hours. The first one I gave her, it took her more than a day to chew off a little ear, but she still love to play with it. The second one is completely intact after more than a week. What both of us like is that the shapes with tiny nubs make the toys bounce unpredictably. They are small and light-weight which makes them easy to throw in the house without doing any damage. I am careful to not throw them at the TV or delicate items. I’ll actually buy them again when she needs more toys. EDIT 3/19/2026: It’s 3.5 months since I first wrote about these toys. Tater is playing with all four critters. It’s a miracle that all of them are intact and squeaking! Even the one with an ear missing squeaks as long as I cover the little hole. I just added all of the Chiwawa toys to favorites so I can find them again—if or when these ever wear out.

Fun Bath Toy - Loud Squeaker

Size: Small

My dog loves these little squeaky toys. The squeaker is loud and the toy is very durable. She can chew on it and it still looks the same. We love to add them into the bathtub when it’s time for a bath to make her less stressed. She loves to bat them around the house. They roll around pretty well.
