Ben isn't a pup anymore. He's a handsome adult!
So making Jake wait for food made him eat more slowly? That is interesting. I have one that is done eating before I even get the the others fed. I have been thinking about getting her a puzzle bowl to slow her down. She has never been told to wait for her food, she isn't pushy about it so I don't really tell her to wait but maybe I can get her to wait a little bit and see if that slows her down.
That's EXACTLY how Lucy would eat....lunging at the waiting sheep as they creep ever closer! Every day,same ritual....sheep weren't really scared by it or they would never have attempted the jaws of death, but there they were at feeding time every day. Poor Lucy had sheep and chickens on one side and Jake eating faster than a piranha on the other...and her with her worn down teeth, trying to eat faster than she likes to do. 
I have closed the gate to keep them out, but she was eating good, so left it open. So naturally she decides to be picky..... LOLMaybe Paris needs a "safe from sheep" place to eat!
