This attack happened just three days before her birthday, and when officers arrived at the scene, she was already dead. Authorities have caught four of the dogs involved with the attack and are still pursuing the other dogs.

The types of dog breeds have not to be released, and the dogs will be turned over to the Walker County Humane Society. District Attorney Bill Adair will decide if there will be any criminal charges.

In a Level 1 Trauma Center Studies Characterizing Dog Bite Injuries Across Major U.S. Geographical Regions (2011-2019), pit bulls cause the most severe damage and injuries than other dog breeds. Pit bulls create the most complex wounds, the most mauling injuries, and the most fractures than other dog breeds. Also, the damage created requires up to five times more operative interventions.

Up to this day, there is an ongoing debate on whether or not Pitbull dogs are born to be dangerous. These dogs have a bad reputation because they were used for dog fighting practices. The actual name for a Pitbull is American Pit Bull Terrier. Nowadays, they are commonly known for their new name and have since been what they are called.

Pitbulls weigh up to about 85 bs and have a height of 19 inches when mature. They are relatively a medium-sized dog and are filled with muscles. They are short-haired dogs that could not tolerate cold weather. Also, they love to get all the attention of their owners. But they have had rough times and now are filling up shelters due to their aggressiveness.

There are about 3,397 cases of Pitbull attacks in the last 30 years, and it is quite a lot. Although they were bred as farm dogs and are good with people, some people train them to attack.

Their aggressiveness is instilled since they were young, so they may participate in illegal dogfighting. This type of activity is banned worldwide; individual dogs cannot find a home due to their aggressiveness.

2. Rottweiler

Rottweiler dogs are a large dog breed that has black fur with a bit of brown. They are bred to be guard dogs and have defense instincts. They were also bred to pull carts and be service dogs in the military. They are considered to be one of the oldest dog breeds in history.

Rottweilers can weigh up to about 130 lbs and have a height of about 27 inches when mature. They love to be the only dog in the house but are reasonably okay with small children. They need regular physical and mental exercise, so they do not get bored. It is better to get a Rottweiler if you are an outdoorsy person. If they lack the attention and care they need, they may become aggressive, leading to potentially dangerous behavior.

In about 30 years of data, there are about 535 reported incidents and attacks caused by Rottweilers. These attacks are sometimes fatal due to them being a large muscular dog with a strong bite force. These attacks, however, are due to negligence and lack of proper training from their owners.

Without control, this could be a hazardous situation. German Shephard’s aggression is usually aimed at strangers but there are numerous cases where they attack their owners.

Since they are one of the most intelligent dog breeds, they can also be challenging to control. Also, most owners get this breed for protection and teach them dangerous tricks that they could not prevent. This then leads to attacks and casualties.

4. Bullmastiff

Another big dog on this list is the Bullmastiff. This large dog weighs about 130 lbs and has a height of 26 inches when mature. It has short hair and features droopy eyes. They are perfect companions for families with behaved children. They are laid-back and quiet but can be suspicious when there are strangers at home. They do not like other people and can be aggressive if threatened.

Also, Bullmastiffs do not like other dogs or animals with them. They want to be the only pet in the household, so it is best not to add another dog or any other pet with this breed. Bullmastiffs were initially bred to protect English estates from poachers. They can run fast and catch poachers easily because of their long legs and powerful muscles. That is why they are dangerous if not appropriately trained.

In the last 30 years, Bullmastiffs have a recorded 111 attacks. They are on the top 5 list of dog breeds that are dangerous and aggressive.

Although dogs are descendants of wolves, wolves are not domesticated animals. Wolf hybrids have both wild and domestic animal traits, which can be dangerous if not properly trained. Wolves hunt for food, and the thrill of hunting fuels them, which could be passed down to a hybrid, and they will see people as prey and not as their master.

In the past years, Wolf hybrids have reportedly attacked over 85 people, some of whom are fatal, and others died. This is why some states in America have banned this dog breed from ensuring safety. Also, neglect from owners is one reason why Wolf Hybrids multiply, yet there is no proper training.

Akita dogs are relatively friendly dogs that love to have all the attention of their owners. They are loyal to their owners and will protect their masters in any situation.

Labradors are large breed dogs and can weigh up to 36 kg as adults. They have a height of up to about 62cm and can live to about 12 years. But, if they are known to be gentle, why are there so many attacks over the last 30 years?

Just like us, dogs have different personalities. Also, the owner can be at fault too. Even the gentlest dog can turn aggressive due to inadequate training and a bad environment. And with labs being a large dog, it can be hard to outrun this. They have powerful jaws that could snap a bone in half, and if they are mistreated or caught off-guard, chances are they will most likely bite and attack.

Why Are Dogs Aggressive?

One of the main reasons some dogs are aggressive is the lack of proper training and socialization from an early age. Even though they are deemed intelligent, they still need to be guided to have the best behavior even when you bring them anywhere.

For first-time dog owners, you must research for a dog that suits your lifestyle before planning on adopting or buying a dog. Individual dogs need a ton of exercises, and some are okay to just lay around at home. You should know the type of dog you are getting and see if this breed fits your personality well.

Also, people tend to forget that just like any other living thing, dogs have feelings, and they can think too. With the population of stray dogs and dog attacks growing every day, make sure that you are fully aware of the responsibility of being a dog owner. With this in mind, you’ll have a loyal companion that is adequately trained and is willing to risk their lives during dangerous situations just to protect you. And in return, they only need to be loved, fed, and be given shelter. You will get the best in life if you are careful with the dog you are willing to take home, take care of, and love.

Aggressive Dog Solutions

There are two options: work on improving the dog’s behavior and/or environment or rehome. Before considering rehoming the dog, always work on improving the dog’s behavior. A dog’s aggression can be seen as losing your own temper so it’s something that can always be worked on. For more about this, we highly suggest you read the Can An Aggressive Dog Be Cured? by
