My 2 1/2 year old doberman/german short haired pointer and she is a smart one. However, My children leave open the pantry door by accident and Bella eats until she throws up. I love her and she just got into the pantry door again and ate until she threw up. She was just seen by a vet less than a month ago and all is healthy. However, my Canine behavior consultant and a certified nutritional specialist, says it's known for dobermans who eat too much if they have access to food. Any advice or other ideas for a tight air container for the dog food??:thanx:
