Not good value for money
I have ordered this before and as the picture shows it used to be a pack of two. I received my ball and now its just one ball for the same price. I will not order this product again.

Will buy again but softer ball preferred
At first Labradors weren’t into it, but I played with them positively reinforcing all touches and now my service dog LOVES the bigger one! It’s perfect between appointments to give her exercise. Will be looking for the same but with a softer ball. It’s a little too heavy and tough if it were to accidentally bounce off a body part besides their mouth catching it.

My dog LOVES this tiny tug ball
Size: Medium(6")
A lot smaller than I was expecting.. BUT my dog doesn’t mind at all. She seriously loves this thing. It goes flat fairly quickly, but that’s what happens with all of her soccer balls, no matter the size. She’s a pitbul catahoula mix and has a strong bite. Considering my dogs chewing abilities, I’m fairly impressed by the durability of the ball, though she chewed through all but one of the rope handles in about 2 seconds. All that said, it’s one of her favorite toys(she’s 13 years old)
