Better than tennis balls for dogs
Color: Orange, Size: Large
My trainer said better for my German Shepherds than tennis balls. They seem to like them, and they last a lot longer than regular tennis balls. We started using regular tennis balls as the dog ones broke first time out. They still managed to break the regular tennis balls also, just not a quickly. Once I found out tennis balls were not good on their teeth I bought these. The rubber ones are great.

The only balls that have lasted with my dogs.
Color: Orange, Size: Large
I own a Southern Black Mouth Cur and a Belgian Malinois. They have destroyed every other ball I purchased in a matter of minuets, except for these. I will not waste my money on any other brand!! Also come in large and small sizes, for at home backyard play or carrying in a pocket. Okay, so my dogs have now had these balls to play with for months and finally put tiny holes in both. The holes are so small you can't see them, but you can hear air escaping when they chew on them. One actually folded in on itself one time but I was able to pop it right back out, throw it again, and watch my happy aggressive chewer catch it on the first bounce. And they both still bounce well! These Chuck It balls are easy to find if left outside because of their bright orange color, rinse off easily with just water when muddy and grunge covered from outdoor play, or you can use any soap or cleaner you prefer without damaging them. Perfect for any dog, big or small - indoors or outside in the dirt. Love these!!
