Ok, when Bava decides he doesnt want to do something or go somewhere, he lays down. Two examples, taking him out to pee , when we are coming back into the house occasionally he will jump into this low lying bushy area close to the front door, and lay down in it, refuses to get up, no matter what. If I go to pick him up he will roll on his back and go into crazy dog play mode. He did it this weekend, while we were doing some exploring closed to the water, he wanted to get in sooo bad, but we had other places to go and couldn't have him muddy / wet with us, so he lays down in the dirt of course walking back out and pouts, and I reach down to pull him up he rolls on his back starts mouthing and kicking his muddy paws, being a big old goof.
If her were a smaller dog, I'd just pull him up by his collar, but not when they're this big, it would probably hurt his throat. We've started making him wear a harness again, so that would help if this happens when he has it on, but I'm sure he won't have his harness on next time this happens, it never works out that way.
It was kind of a cute behavior, and it's probably part of growing up learning the word "no", but it's more of a pain as he gets heavier (he is 90lbs now)
Any ideas?
