Our 8 month old GSD mix, Minsk doesn't have any major behavioral issues, but after giving it a bit of thought it became clear that he thinks he is the Alfa. Its nothing very overt, but the symptoms are clear; terrible recall outside the house, darting all over the dog park and very rambunctious play, marking the outside lounge cushions where we sit, trying to answer the door first when guests come over and not listening to his stay commands in these situations etc. Anyways, we decided that Minsk is a clear candidate for NILF. My question is this: he seems a little bumped out. He has started sitting further away from us, become a bit more stubborn on his basic commands, sitting on our feet, yawning like he is stressed out. It is a bit of a change for him, as we got lax and started giving him lots of rubs, kisses, belly rubs all day and now we probably seem more distant. Do pups, fight the NILF thing at first? When I make him sit at the door and wait for an "ok" before running out he gets a little bratty and gives a little huff like its a huge bother. This new NILF regime has only been for a few days, but it seems like it has started a test of wills that I thought we had already past a few months back. Is this normal?
