Thank you, this is very informative.
So let me see if I have this...
Work her just before meal time then give her the food? And when I say work, I mean the simple commands we are using right now which we consider age appropriate (sit, down, stay, come, get, bring, etc)
or should I do the training then place her meal in the crate for her to eat?
I understand that either way, feed then leave
What I did was - Sit on a kitchen stool with his kibble. His meal was measured out in a bowl. (Not his bowl.) I would hold a few pieces of kibble in my hand. Give a command 'Sit' feed kibble. 'Down' feed kibble. It was very important that he learn to focus on me, so I would hold my handful of kibble near my nose, just below my eye. 'Watch' As soon as he made eye contact, he got kibble. My dog was very food motivated, so he also learned lots of tricks.
After a while, as in months later, I introduced his food bowl. The bowl sat on the floor by my feet. We would start with the commands and hand feeding. Then, after a command, I would drop the food into his bowl. Today, at 4 years old, I fill 'Natty Boh's' bowl, have him perform one command or trick. (Beg is his favorite, so that will work.) Then I sit his bowl down and he eats.
I have never fed Natty Boh in his crate, because I didn't have young kids. I do have a second dog now. She has no resource guarding issues whatsoever. But - I have a baby gate across my kitchen entryway. Natty Boh eats on one side and Shelby eats on the other. I no longer have a problem with Natty Boh growling over his food bowl, but I would still not bother him. I'm pretty sure he would revert right back to square one.
A rescue friend sent me at link that was very helpful, when I was working with the resource guarding issues. I will go find it for you.
