Poppy is puppypad trained and is free to roam around my kicthen and livingroom. She was never creat trained i left her and trusted her in my kicthen with her toys bed and puppy pad along with water and food at the other side of the room. She always did really well and never ate anything... because she had her toys to play with
... and the cat haha!! Now Poppy is a year old and i still would not expect her to hold herself while i am working a 8 hour day. I hope u find day care for Tank as 11 hours being on his own is a very long time
Good luck <3 xxx
