5. Beagle
Beagles can tend to be stubborn and obstinate. According to puppytoob.com, Beagles have a long list of shortcomings, one of which is the tendency to howl and bay. They also shed a lot and have a very distinct odor. All of these are good reasons not to have a Beagle if you live in an apartment, senior living facility, or really anywhere you have neighbors in close proximity.
