4. Pit Bull
It may seem obvious that a pit bull would be a bad choice for a senior, but some retirees choose this breed of dog for protection purposes. Unfortunately, pit bulls usually have an aggressive temperament, making them some of the worst dogs for seniors. They also need plenty of activity and a lot of time to get out of the house and run, which means a pit bull won’t do well in an apartment.
Pit bulls were originally bred in the UK as a cross between a bulldog and a terrier in the 1920s. They were bred to be dog fighters and have rather controversial reputations as a result. More specifically, they are known for having a tendency to attack aggressively and to latch on to their victim while biting.
While they can be trained, they require a lot of it, which must be done by a skilled dog trainer. All in all, they are among the worst dogs for seniors, so retirees may want to consider other dog breeds.
