My doberman loves my chickens. When they geat meal worm treats they all forrage together. The hens follow her around all afternoon when they come out to free range. I cant speak for all doby's but shes a perfect match.
I have a pet large munsterlander who's allowed access to the garden (with the chickens, about an acre) whenever he likes through a dog flap. I think he's one of the reasons we still have so many chickens, because of the foxes around here.
He kills pheasants (when he catches them, he's usually pointing at them) and rabbits (when he actually gets them, he generally runs round like an idiot) very quickly, but he knows to protect the chickens. He loves chasing the chickens out of the house, though, which we allow.
Not having a dog that gets on with the chickens could well cost you chickens because of the foxes.
I never trained my boxer to be good with other animals, I think its just his nature. He's only interested in animals that want to play. I do think certain breeds can be more trusted around small animals. I wouldn't get a terrier or hound and expect them to not instinctually hunt. Some breeds have such a strong hunting instinct they go into "tunnel vision" there's no stopping them except for keeping them separated.
Hi, I saw your question as to a breed who is Ok with chickens.
Most people don't know it but the answer is a Maremma. No one in the US has herd of Marrema's but they are a legitimate breed.
I have one and it guards my chickens.
I had one prior to my puppy now that watched over the chickens. He did a loyal job without fail. They are a bit hard headed. They will sit and stay and come, but they don't want to play with a ball or tug a rope - they want their land and their flock. Farmers use them all the time. They happen to get quite large and they are all white - all of them.
They will guard anything they are raised with. You can see a Youtube video of a Maremma they put on an island to protect penguins from a fox problem they had devastating the endangered population. They put a couple Maremmas on the island and the penguin population came right back. They will guard anything.
Also, they are a guarding sheepdog in lieu of a shepherding dog or a guard dog. The Maremma will charge anything that comes into the yard it sees as something strange, but it won't engage. That's important that it won't engage, but will bark like hell. It simply adopts it's land and animals and won't eat the animals (no matter what they are) and fend off intruders. It will get used to neighbors it knows and learn they are "normal to have come and go". Others get the bark.
Also it tends to perch and look over it's property - especially at night. That is what it naturally wants to do. Because it tends to be a bit nocturnal, the Maremma sleeps a lot during the day. It always is on the alert though
They are a bit rare here in the states but are popular in Italy where they call them Maremma Abrizies.
Great dogs and I'd do a google search on them. They are hard to find, but I found a breeder in Kentuckey and am raising a pup right now.
Maremma - they'll adopt and protect your flock without eating them. Stubborn as hell too.
