Having both dogs and birds in the same household, raises the issue of the safety of the birds. If you do opt for the mixed pet household, no dog should ever be allowed in any room where a bird is free. And even when caged, no dog should be left alone with a bird. This can avoid a tragedy. Here is why dogs and birds will never make a trustworthy team.
Dogs are predators.
They hunt mostly by smell, but movement attracts their attention and stimulates the hunt. Birds, as all of you probably have noticed, like moving. In fact, they make quick rapid moves, the most inviting type of movement. To a dog this is as good as waving a flag in front of a bull. While dogs have never had the reputation for killing birds that cats have, they also have never really had the opportunity, until birds are brought into the house.
