Our children used to have a dog like that ( a soft toy) called Sprocket it was from a childrens tv show that was all puppets. In fact when I saw the add I thought that it was Sprocket. I shall have to google it now to find out the tv show name.
I have also fallen for that dog. A dog that is that cute, doesn't bark or need picking up after. My mind of dog. I would like one to go with Snoopy who is over 40 now.
My dog sits waiting for it then stands in front of the tv barking loudly, even though I keep telling him it's not a real dog. Maybe he should get out more too!
