Toto's been willing to play with plastic bottles but I had been hesitant thinking that he would easily break them. But then his fellow brother maltese was playing with a plastic bottle so I decided to give 1 to him as a toy. He was so fascinated and excited that he ended up rolling the bottle under the furniture. He at first gave up but then squeezed himself in to get the bottle and was stuck beneath. Let's get you out of there Toto.
