I have a 7 lb. toy schnauzer who totally LOVES this ball.  Its big for her but there are holes in the ball and she puts her teeth in there and can carry it all around.  She will even at times lay down with it still in her mouth. She doesn't want to give it up.  She will play for hours with it. She has tons of toys and this is her second favorite out of all her toys.  Her top favorite is the babble ball.
