I have 6 dogs, and only one do I trust. And the funny thing is, he's a breed that you usually wouldn't trust! He's a mini daschaund! But he is the complete opposite of the typical daschaund. He doesn't bark excessively, he ADORES kids, no matter the age, he welcomes strangers with a big kiss, and is the most gentle thing you could ever meet. He's the only one I really trust to bring around the birds with me. I also have 2 chihuahuas (my male will eat baby chicks if they are close enough for him to get to, yet he's gentle in every other way!), a pomeranian that hates everything, including most other dogs, all cats, and most other animals. We've only had her for 5 months and she was given to us to save her the fate of ending up in a shelter because she has so many issues from abuse as a young dog before her last owners got her, but she fit in pretty good here. But I still don't trust her around my birds. Probably never will. I also have a black lab mix that would probably try to use the birds as chew toys if given the chance (she is absolutely the DUMBEST dog I have ever met, and there is not a single command that she will heed except sit), and a chow/old english sheepdog mix that I don't trust alone even with the other dogs. She and the lab decided suddenly last summer that they hated each other and attacked one another to kill. They now can no longer be in the same room. She has snatched wild birds out of mid air and ripped their throats out, so there is NO way I would trust her around my chickens. On the few occasions that she escaped her leash, she headed straight for my coop and was trying to tear her way in, snarling and barking the whole time. Thankfully my birds were locked up at the time. She is NOT bird friendly at all, or small animal friendly. She's 6 now and I've had her since she was 4 months old, and I love the old mutt,, but I don't trust her any farther than I can throw her. Each dog is different, and I think that a lot of how the dog will react around your birds is dependent on what they were bred for as well as how they are introduced to the birds. Sometimes though, a dog will surprise you, like my daschaund. He's actually afraid of the birds and keeps a respectful distance. Down the road, should I get another dog, I will definitely take into consideration the dog's breed, temperment, and what they were bred for. No more hunting dogs or bird dogs!
