Our girls can't pick up their bowl as they are porcelain heavy things.. I'm sure one day when they get bigger they'll try!
Our puppies hungry buttons haven't been switched on yet. When ever we put food down, they just walk away and eat it 10 minutes later when they realise I'm going to take it away.. We've been told one day that button will be switched to the on position and broken so it can't be put back to the off position!
We also use porcelain heavy things.. They actually regulate themselves. I put 2/3 cup in each bowl in the morning and again at around 5. Sometimes the girls eat breakfast and sometimes they don't. Now that it's gotten warmer, they prefer to eat most of their food in the evening. If one does not get enough on one day, she makes up for it the next and visa versa.
