I did buy Ryder three tennis balls, but I'm not sure about that anymore because it was only a $1 from the Dollar Store. Maybe I should ditch them? I ended up buying him a 6 inch blue Jolly Ball with a handle - so I think he might like that - just have to supervise, so he doesn't chew off the handle or anything like that!
I would absolutely ditch them, as I bet they are "made in China" and if so, you have no idea what is in or on them anyway! Better safe than sorry!
