What’s wrong with leaving food out and letting the dog graze throughout the day?
Anything that requires an effort is more appreciated. Things that are taken for granted are not as desirable. So if food is available all the time it becomes much less likely to be a motivating force and is more likely to create a fussy eater.
Fussy eaters are more difficult to reward and can therefore develop behavior issues that are harder to remedy. However, that fussiness can be prevented or remedied easily by making food a valuable commodity.
Additionally, teaching your dog that he does not have to worry about his food or his bowl will prevent resource guarding. For guidance and solutions to this important topic, let DogRelations give you a private dog behavior lesson and show you the many ways you can make feeding fun and educational at the same time.
