Wow Pat! That is a lot of information. Thank you. Looks like I have a lot of work ahead of me. :o One question though..Should I still continue to pet him while he eats and If he growls take his food away?
I would absolutely not do the above. He will most likely bite you. He is telling you that you are way over his threshold of comfort. It is not about you being in charge here…it is about you needing to change his opinion of what is about to happen when someone approaches his food. We don't want to let him practice the behavior of guarding/growling at all..he will only get better at it (and escalate it)
PLEASE read "Mine!" by Jean Donaldson, or "Culture Clash" has a section on resource guarding, also by Jean Donaldson. You can google "resource guarding" and find lots of info online too.
