These fascinating dogs have a powerful prey drive, Akitas were originally bred to hunt wild animals, and if not trained properly, they can become aggressive. Akitas can also be very protective of their owner, making them a potential threat to others if they aren’t trained properly.
Akitas also have a reputation for being challenging when it comes to raising them.
Irish Setter
Irish setters have a very high energy level. With their high spirits can make it difficult to train them for long periods. Shorter training sessions are most suitable for these upbeat yet gentle dogs.
The Irish setter stays a puppy for a long time, this means that an Irish setter will keep its adorable puppy personality for longer than other breeds, which also means more work training him, as well.
Pug
Their charming personalities can often lead to being a little on the mischievous side but Pugs also want to please their human family, with that being said they may take much longer to be house-trained.
They also detest being outside, so many try to avoid going outside when it’s cold or rainy. Plus, these little critters rarely show any remorse when they have an “accident” on your floor.
Labrador
Labradors may be America’s most popular, but they can be difficult for an inexperienced dog owner to raise properly. Until they reach full maturity, they have a strong urge to chew and can be destructive if left on their own.
And if Labs are not trained properly, they tend to pull their owners while being walked on the leash. Labradors also shed a lot, so expect to find their hair all over your house.
Newfoundland
Newfoundlands are gentle giants, but they can also be the toughest dogs to own if not well-trained early on, as they can easily out-muscle most owners. In addition, Newfoundlands are definitely not a good match for those who want a tidy home as they tend to slobber and also heavily shed twice a year.
Because of their size, they can be destructive without even meaning to – knocking over whatever comes in their path while just being playful.
