I think the key here is to understand that if you can't fix it, then you have to manage it. Throwing the dog out to avoid having to manage (your husbands plan) just smacks of lazy to me. Sorry.
I wouldnt say lazy per se, my hubby is not really an animal person, I am the crazy dog lady of the familiy
His solution for any animal problem is dont have them.
Plus he doesnt want a law suite, considering how sue happy people are now a days, his fears are not unjustifiedI guess i am more or less just venting my frustrations that my dog could do something like this. I have always prided myself on having well behaved dogs, and it frustrates me when one doesnt act normal, but I guess shelties really arent normal.
I will manage him, and keep him seperate from company when they are leaving, and keep him inside when the girls are outside. He has no issues when they are there just when they try to go. The size of the chicken run isnt the problem as it is 10 ft. by 50 ft. its mostly mud right now, and I am too lazy to bathe him all the time, plus I dont want him eating chicken poop

Nephew didn't know Sammie was running up behind him, it really startled him. Luckily, he had on jeans so there was no contact. Nephew laughed it off, said 'hey your dog just bit my butt!' no harm no foul.
