Oscar is 9 weeks old now. No matter what it is we are eating, he will beg for it and do anything to try and get some. Its like he goes into a frenzied state. Ice cream, bread, meat, cereal, etc. He has bitten me and my 8 year old once each (confusing our fingers with food). Is there any way to stop this behavior or do we just need to lock him up when we eat?
