This is what my Blind Guy, Colby lives for... stimulus is so necessary for this breed of dog. If the weather isn't cooperating, then he has plenty of indoor toys that he'll bring to me where I have to comply, interacting with him and getting majorly goobered. If I try ignoring him, he'll see to it that he's not going anywhere and will always get his way but it's all good. He always makes us laugh.
As you can see, he loses track of where you are when bringing the ball back so we have to clap or talk to him and then he has no problem.
And, hey! that music track is by my talented brother, Guy who played and recorded this in his studio and sent to me. Whoo hoo! Great guitar player.
