1. Dalmatian
The Dalmatian is no doubt an iconic dog.  Disney made us love them, but there's a reason Pongo and Perdy met on a walk! They are high-energy dogs who require a lot of exercise. If not given enough outdoor time, they can become destructive indoors. They are also stubborn and difficult to train. In addition, according to puppytoob.com, they can be fearful or overly aggressive, depending on their lineage. All red flags for retirees looking for a chill companion in their golden years.
