Mostly happens when he is asked move over in the bed or get off and into his own bed which is in the corner of our bedroom. There is never food in the bedroom. He knows the command "get into bed" and does so eventually.
Happens mostly but not exclusively at night or in the morning, room both light and dark, has attacked both of us at different times. This morning was particularly savage. I held my ground while issuing a firm but quiet command but he went on the attack. We were both there as was the other dog.
Sometimes doesn't like to be stroked along his back even when snuggled up to one of us on the couch. we don't loom over him or come up behind him unawares.
He is very food-aggressive and tries to steal the other dog's food but we have that under control by supervising feeding times closely; at the same time he will take a treat very politely in his turn after giving the paw.
Sometimes just casually watching him you can see his eyes darken and he starts to growl even when no one is approaching him.
Immediately after each episode of attempted biting he tries to climb up on you displaying lots of affection.
We are mystified and can't let this go on - any help appreciated.
Should we return the affection when it's offered, or try to ignore it? It's difficult to ignore a puppy but we will if necessary.
Thanks help we will contact a trainer asap rgds
