It's their breed standard, and I'm standing by it. Myself and many of you I know take a stance of "better safe than sorry". We all want to believe our pooches are innocent and couldn't hurt a fly, but I see post after post after post of duck owners who have lost their birds to dog attacks. Every time a dog attacks a human, what do you hear from the owners? "I can't believe my dog would do this, he's never ever shown any aggression before".
I own cats. I love 'em and I'd defend them to anyone who said they hated them. But I at least acknowledge that as predators they are fully equipped and capable of harming or even killing my ducks. That is a fact. It is no different with a dog, especially ones that are notoriously tenacious and bred for chasing instinct. If yours is well trained and everyone gets along just fine in the present, good for you. But that is never a guarantee that something won't happen down the line, or that it won't happen to someone else.
For all of you folks with dogs that can access your ducks, if nothing has gone wrong, you should consider yourself lucky. I believe in erring on the side of caution, as mentioned above, "better safe than sorry". Regardless of breed, canines do have an innate prey drive. Things could go wrong in an instant. There's no way to know what could trigger a dog to behave instinctually. A clap of thunder, a screaming baby, something dropped on the kitchen floor, a running duck...
Amy hasn't provided any type of false information. She provided breed specific information. Any dog, no matter how well behaved, can turn on a duck. My father had a Jack Russell. Best dog in the world for ten years. As the dog aged, he simply became crabby. In the end, my dad had to help the dog up the steps. One day my dad, doing the same thing he always did by helping the dog up the steps, got bit when the dog turned on him and my dad had to get over 30 stitches in his arm. I bet that same bite would have killed a duck.
