Life isn't always a walk in the park.

Sometimes, we find ourselves in difficult situations and there's no way of helping that. But, according to Clint Emerson, a retired Navy Seal and an expert in all things "survival," you never know what you may need to do in order to escape danger, so it is important to be prepared even inside your own home.

However, one woman was not prepared for her own pet dog to attack and kill her in her living room. Keep scrolling to find out what happened to the vicious pup.

Dog attacks are on the rise.

Though fatal attacks are more of a rare occurrence, the number of people being bitten is not. Over 4.5 million Americans are injured by dogs every year and over thirteen thousand of them end up hospitalized.

This is why Clint Emerson says we should be prepared at all times.

Clint Emerson is a retired Navy SEAL. Who better to get survival advice from than a man that has overcome plenty of these kinds of situations? In order to avoid further casualties in situations involving dogs, Emerson has taken it upon himself to highlight some important rules when dealing with a canine attack.

1. Guard yourself.

The first and probably most important rule. This is going to make or break the rest of the altercation. If you have to defend yourself from an animal with sharp teeth, you must be able to protect the vital parts of your body, because once the teeth sink in there, they'll rip your flesh right off.

Emerson urges you to find something to distract the dog.

Use your jacket, a purse, or anything else that the dog can go after as opposed to you. Keep the dog distracted for as long as you can so you can have time to come up with a plan or run away.

"Take your shirt off," Emerson says, "put it around your arm".

This will help to protect the vital arteries near your wrist. If the dog manages to pierce that area, you will lose too much blood and won't have the power to fend the animal off. This is why this rule is the most important. If you don't have anything like that on you, give the dog your forearm rather than your hand or the inside of your arm, as it will only be able to bite into flesh there.

2. Punch the animal in the nose and the muzzle.

The reason for this is that it serves as a direct, open target. It is the front and center of the animal so it will be easy to aim for. This will maim the dog, giving you some extra time.

You can also go for other areas of the body.

Emerson gives other options too. If you can't directly go for the dog's muzzle, you can go for the eyes or other sensitive areas of the body like its legs.

But the reality of this is that they are small targets.

You're more likely to miss in those areas or they can be too hard to get to, which might give the animal an upper hand. So you're better off going for bigger targets, like the face, if you can.

Emerson emphasizes that a dog attack is an extremely stressful situation.

This means that your "gross motor skills" (abilities that involve large muscles in the arms and legs) are probably going to be the only thing in action, so you must use them to your advantage.

3. Kick the dog near the ribcage.

If all else is failing, this will be the technique that saves your life. Kicking the attacker will create some separation between the two of you and, because that area is also very sensitive, you'll probably hurt it enough to leave you alone.

4. Fight with a vengeance.

The last rule is pretty simple. If you're going to go into battle against something as vicious as an aggressive dog, make sure you fight with a vengeance. It will be difficult because you won't want to hurt the animal, but your life will be at risk and you must protect yourself. Emerson sums it up pretty accurately: you must "try and make the dog understand that you are the alpha".

But even with these rules in mind, you can never predict a situation if it catches you off guard.

A woman from Chicago, Illinois was killed by her dog in what is described as a "vicious attack."

The fifty-six-year-old was extensively scratched and bitten.

There had clearly been a struggle between her and the dog, whom she loved very dearly.

Blue was one of 3 dogs in the household who were all found with blood on them.

It is unclear if any of the other 2 dogs had been involved in the initial attack. Urso was bleeding heavily and had her clothes torn by the French Bulldog, but she still managed to make it out onto her porch to call for help.

But in the end, Urso succumbed to her injuries.

She was later found by her friends, who immediately called the police.

Lake County Coroner Dr. Howard Cooper told PEOPLE this:

"There was a struggle," Cooper said. "She was being attacked; there's no question. We know one is an aggressive dog who had bitten someone before."

Blue was only two years old but weighed an impressive fifty-five pounds.

According to Cooper and county Animal Care and Control Department Program Manager Robin Van Sickle, there were claims that Blue had been bred to be a fighting dog when he was younger. But when taken under the care of Urso, he was well-taken care of, as were the other pets.

He had previously also bitten Urso's boyfriend, who required stitches after the assault.

"That incident prompted the dog to be taken and held under a 10-day quarantine, during which 'he did not give cause for any concern. He did not show any aggressive behaviors.'"

However, just under a month later, he struck again, this time killing his owner.

Even though it was Urso who asked for him back because she missed him, he still attacked her. "She loved that animal," Cooper said. "If she ever thought it would have attacked her, I'm sure she wouldn't have wanted it back. Clearly she believed she was fine with him."

Van Sickle noticed a strange turn in his behavior.

After the horrendous incident, all 3 dogs were taken back to the shelter where Blue was displaying some very aggressive traits, things they didn't notice the last time they came into contact with him.

"He's very aggressive."

"He fixates on you. He growls, barks, lunges…he's targeting," Van Sickle said, after some close analysis.

It was also mentioned that Blue will now be "humanely euthanized."

This was a terrible incident and we all hoped the circumstances could have been different. RIP Lisa Urso. Keep scrolling to see some happier dog-related news. This is bound to make you smile...
