A career with K-9's would definitely be awesome in my opinion. What would some career options be?

You should have included your age range, it would have made the question easier to answer. It would be unwise to work police K-9 unless being a cop was the ultimate goal. The dog helps you in your cop work which if you have no interest in it wouldn't work out. I worked K-9 for many years and it's very rewarding. The USDA thing might be a good one if you have or know how how to train dogs for that line of work. If you haven't utilised working dogs before then my advise would be to join an obedience club. Learn how to train, work and deploy working dogs. One of the problems is that every handler thinks he's a trainer and vice-versa. Training a dog is not the same skill set as being the human half of the equation when you deploy the dog. And handling the dog has nothing to do with being able to properly train one, although some attributes overlap. The main thing about working a dog is that you have to work it to some end. As with the police thing, if USDA inspection isn't a passion then working this just to be with a dog is a waste of your time and ultimately a waste of your dog. There is lot you and a dog can do together without having to "work" at something.
