What is the advantage of feeding only twice a day?
I don't actually know
All the dogs we had when I was growing up were fed twice a day and I guess that has just stuck with me with my own dogs
Dallas would think it was christmas every day if he got fed 3 times a day
My uncles collie was fed once a day - his food would be put down in the morning and he would just graze at it throughout the day. None of mine would be so self-disciplined!
