Think Before You Leap – Bad Puppy Breed Choices for a Pet

By Yuri S.

Puppies: cute ideal companions to play with whenever we are bored or feeling low. They grow up to be dogs, a best friend of the human as has been declared for ages. A world without pet dogs is unimaginable for most people, and some of us cannot get enough of the cute and quirky dog and puppy videos people post online.

We are all looking forward to eventually having a puppy to play with. However, not all puppies are built equally, and by puppies, we specifically mean puppy breeds. Some puppies are more suitable for pets than others, while some species of puppies are downright dangerous. Some veterinarians have also recommended against adopting certain breeds of puppies for several reasons, including aggressiveness, extreme grooming requirements, and lethal danger to kids.

Here are a few dog and puppy breeds that have fallen into the list of undesirable choices for getting adopted by humans. Be very careful if you were planning to get a puppy for yourself. This list might help prioritize what to do.

Its ability to catch prey was quite useful in the olden days as it was used for hunting gazelles and even other rodents, which required a very speedy hunter to catch. Although trainable to respond kindly to people, its training routine and daily grooming practices alone are going to leave you with no time.

Border Collie

A border collie is an ideal dog for several reasons, but the extremities of all those good reasons make it a bad dog breed to keep as a pet.

For this reason, people who are neat freaks should never ever own a Newfoundland, or they will have a terrible time cleaning the place every day.

American English Coonhound

The American English Coonhound is a very interesting animal that leaves a trail of chewed up things everywhere it goes. If it’s even slightly boring, its first instinct is to chew off something. It makes for a very difficult pet as its training routine is very intense and requires a lot of effort.

It is also an attention deficit most of the time, and you are required to spend most of your time with it if you want it to behave decently well. Its long legs and body make it a dangerous mass born just for knocking things down.

They are also quite annoying due to their barking habits and do not easily stop on command. Training them to stop barking when asked to is a nightmare.

The Boxer

The Boxer is a relatively easier breed to keep as a pet despite its menacingly dangerous sounding name. It is also not a very aggressive breed, considering how well it gets along with people it is familiar with. However, it is very difficult to train and requires a lot of time to exercise.

Another problem with this pet is its frequent mood swings. It may sometimes look seemingly harmless but might eventually become aggressive if not properly trained.

They also have a reputation for being quite difficult to train and require ample space to run around, failing which their claustrophobia might cause damage to property.

Alaskan Malamute

Alaskan Malamutes, like the Malamutes, are required to undergo active training and exercise regimens to prevent their sled dog reputation from getting tampered with. They tend to go aloof and sometimes turn into very aggressive creatures if neglected and left untrained.

While they are ideal dogs for hilly regions and make great sled pullers, they are not very safe to keep around in domestic regions or cities where there is little to no scope for their activity and exercise.

Japanese Tosa

Tosas were majorly bred for sporting events like dogfights. The Japanese Tosa is no different. A major contender for the title of the most dangerous pet dog to own, the Japanese Tosas requires a lot of time for training and exercise.

Another Japanese dog breed, the Akita Inu, is a very aggressive dog with fierce hunting origins. Owing to its history, these dogs tend to adapt their hunting instincts when they are around other smaller pets.

They are also very difficult for their masters to control and undergo a lot of training before being tame and friendly even to their masters. Akita Inus are also quite dangerous to be left out in the open where they could do serious harm to strangers.

American Bulldog

The American Bulldog, like its English counterpart, is quite an aggressive animal. It is very steadfast, muscular, and strong to fight with and will take a major toll on any animal that decides to fight it. Without training, the American Bulldog is almost impossible to keep as a pet.

Therefore, American Bulldogs make better pets of people who have extensively trained animals before, are aware of how a bulldog behaves, and know how to control it when it gets out of hand.

American Bandogge

Bandogges are a crossbreed born out of a Pit Bull Terrier and a Neopolitan Mastiff. They are aggressive by nature and tend to feel very angry and furious whenever provoked by other dogs.

However, if they are trained from an early age, they tend to become great caretakers of the children and adults alike and can be very loyal and trustworthy. They are also quite aggressive because of their origins as fighting dogs and will go to any lengths if they hate another animal.

Wolf Hybrids

Wolf Hybrids, as their names suggest, are dog breeds that are interbred with wolves. Although relatively tame when trained, they have certain tendencies to attack people owing to their wolf ancestry. It is, therefore, customary to be very careful while buying these hybrids as pets and keeping them near human settlements.

These pets require a lot of training and screening to ensure that they do not have any predatory intent, as that can be very dangerous around small animals and even children.

Gull Dong

Gull Dong, or the Pakistani Bulldog, is a breed of dog hailing from Pakistan. They are said to be quite aggressive as they were bred to be watchdogs and not as family pets. They, too, like most other bulldogs, require a lot of training, failing which they tend to be very destructive.

They are known to be very agile and quick and require an ample landmass to run around and train every day. They are slightly dangerous to keep around small children and are better suited as dogs kept outside the house to guard the fields or any other such settlement.

Tibetan Mastiff

The Tibetan Mastiff has an interesting backstory. It is known for protecting entire villages with its fierce grit. It is knotted to a long stick in the middle of the village at a very early age to condition it against obstacles. It is then left to roam about, which trains it to guard the village from unwanted people or animals.

Photo By Getty Images/ Leon Photography

All this sounds great, but to keep the Tibetan Mastiff as a house pet is no good idea at all. They are very aggressive creatures, and even though they love their masters a lot, they tend to be very dangerous to other people.

Staffordshire Bull Terrier

The Staffordshire Bull Terrier is very similar to the Pit Bull in several respects. Case in point, it is also equally aggressive if not more aggressive than a Pit Bull, which is why experts recommend against getting this Bull Terrier as a pet in a family setting.

They also require a lot of intensively monitored training and exercise before they can be deemed safe around children and other members of the family.

The Moscow Watchdog

The Moscow Watchdog is a very aggressive dog breed that was used in heavy numbers as a dog for Russian military services.
