I have a 4 month old Cocker Spaniel, we are having issues with him lunging at our faces when we are sitting with him or carrying him/holding him, he doesn't usually make contact but thats probably more due to quick reactions on mine and my partners part! I think it's become a bit of a game to him, he lunges we pull our head back to avoid being bitten. On the occasions when he has caught us he doesn't bite hard he just nips but because it's my face it hurts if he catches nose, lips etc. I have looked online and although this seems to be normal puppy behaviour that he will (hopefully) grow out of, there are lots of different recommendations as to how to deal with it: 1) Stand up and stay still - become 'un-fun' 2) Leave the room for 1 - 2 minutes 3) Put the puppy in a confined area such as crate or a room on his own 4) make a yelping sound 5) say 'ah ah' or 'no' in a firm tone I'm so confused as to what method to use and want to be consistent. Has anyone else experienced the lunging and have any tips on how to deal with it? Also at what age should he have grow out of it (as in when do I need to worry if he is still doing it)?
