Beagle, a dog that likes to bark, with a bark that is high pitched and annoying.

As for Jack Russell's, I have had two and they are intelligent, loyal, protective and loving. They are also very stubborn, high energy, hunters and sometimes lacking in common sense.
The stubborn part requires their owner to REALLY be in charge and make sure the Jack Russell knows it. The hunting part is in the breeding and while you can minimize their desire to kill things and usually prevent it, you can not train it out of them. The high energy is also part of the breed and generally requires a fenced in yard where they can run or lots of walks.

Jack Russell's really aren't recommend for the novice dog owner or someone that lives in an apartment or other space where they can't get their exercise.
