Review on Penn QST 36 Tennis Balls - Youth Red Felt Tennis Balls for Beginner Players by Michael Powell

She loves them. She has a soft mouth and doesn't usually break things, they are a bit big for her but the material is a bit pliable so she can hold it quite well. I wasn't sure if she would like them as the reviews said they weren't that effective, but she might have preferred these. Not a little girl, but thanks to her boisterous genetics, she has a shorter muzzle. I bought these because she prefers balls in contrasting colors, so a good choice if that's your thing. hit our kitchen counter. Many reviews say it's great for indoor play, but we're more cautious! They are great outdoors too, I try to keep them low so we don't lose them in the woods behind our yard and they trip while chasing them unlike normal tennis balls. They hold their attention longer. The downside is that they don't fit in a cartridge and on the other hand they still work if you crush them and they FLY if released so another thing to be careful with. I am planning to order a pack of 12 as the balls will disappear in our garden for a few days and then reappear so well that there are several to spin.
