feeding time has become a nightmare..my sweet baby becomes demonic!! his fangs come out and he is in full aggression mode..i basically put the food down...i make him sit first, and then place it in his xpen...he will immediately start to growl and wont eat until i walk away...if i attempt to come near him, all hell breaks loose...he is almost 7 months and weighs 9lbs...any help or advice? i know at this point i have to contact a behaviorist...he has already bitten me several times.
