Nice ball w/straps to grab for ur dog to carry the ball.
Size: Medium(6")
She’s afraid of SO many things. Gotta give her more time. From a hoarding group…so, no socializing. Time will tell. Very nice ball w/ tough straps to grab hold of & carry it.

Energy burn
This interactive dog ball is a total game changer! The automatic rolling and bouncing keeps my dog entertained for long stretches, and the lights make it even more exciting, in the evening. I love that it’s rechargeable and waterproof, so we can use it both indoors and outside without worry. It feels durable and well-made, perfect for medium to large dogs. Also works great with toddlers.
