if you honestly think any domesticated animal is better than a dog you're a fucking retard and should qualify for special education. for hundreds, nay, thousands of years, dogs have been hunting, protecting, and everything you can imagine in between because we trained them to do so.
If you disagree, watch this video of border collies in the British Isles herding sheep with LED lights on their backs. If you watch this video and still honestly think any other domesticated animal > dog, you are an idiot.
