I have an Aussie/Lab mix who is 15 yrs old. She has always been the "momma" to everything I have ever brought home to her. I was a vet tech for 9 yrs so you can only imagine the kittens, puppies, baby squirrels, etc that have come into the house. Anyway she does just fine with the chickens. Says Hi and then lays down or walks away totally uninterested with them. I also have a 5 yr old Terrier Daschund mix who is well......a terrier!! She would love nothing more than to rip them to shreds and then brag about it. I know this about her so I always have her in a kennel when I must bring a chicken into the house. She has escaped from the house due to a door being left open and where did she go? Well considering I was in the coop, she ran out, storming the coop and chased them all around. Luckily she did no damage to any of the chickens other than scaring them half to death. Point is that dogs can be kept while you are keeping chickens but as you have already stated, they are not to be trusted. You should treat them like you would when bringing a baby into the house. The baby is never left unattended with any dog, ever. Not necessarily because the dog may do something malicious but you never know when the baby or child may do something to the dog resulting in an "accident". Its not hard to do, so enjoy those dogs and get some chickens stat!! You will love it.
