I have a food obsessed beagle.
He will eat anything at anytime.
He gets fed ONCE a day olnly at 6pmish. From 4pm he is begging and carrying on. When he was fed twice a day it was the same behaviour but twice a day instead of once...
He does get a bone 3 or 4 times a week in the middle of the day.
He is on the heavier side or his good wt range (but not in the overwt catagory).
