Dog the Bounty Hunter has had a turbulent couple of years.

Only last year, his long-term wife, Beth, passed away from throat cancer and, ever since, he has been embroiled in controversy regarding his love life. But let's start from the beginning...

It all started in 1986.

Beth was only nineteen years old when she met Dog. The situation was difficult as Dog was already married, but this didn’t stop the pair from striking up an on-off relationship.

They called it quits when Beth married Keith Barmore...

But it didn't last for Beth and Keith and, after a couple of years, they decided a divorce would be best for both of them.

Dog's marriage didn't last either...

So the two former lovers reunited in 1995, before getting married in 2006.

The couple went on to have 2 children, and they stayed together ever since.

And then Dog the Bounty Hunter, the TV show that propelled them to superstardom, came along. The show was based on the life and experiences of Duane, who bounty hunts for a living.

The show became a hit after people fell in love with the couple.

It was so popular that they ended up getting their very own spin-off show: Dog & Beth: On The Hunt.

Both of them worked hard to earn their celebrity statuses.

Beth and Dog were said to have tracked down over six-thousand criminals and made over $4 million in bonds that they’ve won as a consequence of catching them. The pair very quickly became recognized as the brash and outrageously hilarious couple that they have been till the very end.

Their constant bickering was comedy gold.

A lot of other married couples felt as though they could relate to them, which only helped them grow in popularity.

Things seemed to be going well for them, but then Beth shared some tragic news.

She announced that she had been diagnosed with stage 2 throat cancer. Despite being told that she was free of the disease only 3 months later, the cancer returned in 2018. This lead to Beth having to undergo an emergency operation to remove a mass on her throat.

Even though the operation was a success, there was more bad news for Beth.

It was discovered that the cancer had spread to both her throat and her lungs and that it was, unfortunately, incurable.

Beth was in love with her job, so vowed to spend her final days "on the hunt."

Somehow, the family managed to come to terms with this tragedy, and Beth wanted nothing more than to spend her last days doing what she did best on America’s Most Wanted.

But, unfortunately, Beth's health continued to deteriorate...

After resting at home in recovery from further treatment, Beth was taken to Queen’s Medical Centre in Hawaii after having difficulty breathing. According to reports, she began fighting against the help of doctors and it was understood that she was attempting to remove the tubes that were in place to feed her medication and fluids.

She wasn't "reacting well" to treatment.

Beth had to be given oxygen in order to breathe when she arrived at the ER. According to TMZ, medics first put her under mild sedation but she quickly fell into a full medically-induced coma.

Beth and her family refused to give up hope.

Despite the doctors telling her that her cancer was incurable, her family continued to support her, hoping for a miracle. The whole world was just praying that she pulled through this difficult time.

Sadly, Beth passed away in her home in Hawaii.

Her husband broke the news that everyone was dreading in a tweet that ended: "See you on the other side."

It was an incredibly difficult time for Dog and the rest of Beth's family.

After his wife's death, Dog found it really difficult to cope. The impact of the tragic event really had a toll on his mental and physical wellbeing.

In the following days, the bounty hunter lost an alarming amount of weight.

His physical health suffered tremendously as he lost seventeen pounds within 2 days. He was also in and out of the hospital as he suffered from what were described as "severe" heart conditions and depression symptoms in the weeks that came.

He even attempted suicide.

Dog the Bounty Hunter revealed that he was actually contemplating taking his own life due to the downward spiral he was heading in after Beth passed.

During the filming of the finale for Dogs Most Wanted, the TV star broke down.

In his own words, he described his feelings: "I don’t realize yet psychologically that she’s gone, gone and I’ll never, ever see her. I don’t realize that. I just hope that I don’t live very much longer without her, because now she made the first step, she’s through the gate. She paved a way for me. I want to take a god damn pain pill so bad."

He also mentioned that Beth wouldn't be happy if he did go through with the plan.

"I got to heaven and was like, 'Hi honey,' and would she go, 'You d*****s, why would you do that?'"

But now it seems things are looking up for the star.

He's recently revealed he's found love again with Francie Frane - and it seems the 2 are quarantining together.

But not everyone is too happy with his new love life.

Since he and Francie went public with their relationship, Dog has been receiving an awful lot of backlash.

His online behavior seems to have caused quite a stir among fans.

Dog has been behaving quite bizarrely on social media, and his photos of Francie contain some rather questionable captions.

He captioned a photo of his new lover with this alarming sentence:

"I scream & Cry Beth where are you why did you leave me then I look up & see you Francie & the pain turns to a smile I LOVE YOU WOMAN !!"

Very bizarre, I know...

And things have just got a whole lot more controversial.

Earlier in the month, we found out that Dog had proposed to Francie.

The widower reportedly got down on one knee at a romantic dinner at their home in Colorado, only ten months after the death of his wife.

According to reports, he couldn't be happier.

The reality star told The Sun that he's "so happy", and that he wants to have the "biggest wedding there's ever been," open to all his fans, in what he says will be "one hell of a party."

Francie spoke of their romantic moment.

She said: "I wasn't expecting it at all. think I had gone to pick up some food and then when I came back he had all the lights turned down with just a few lights on and a bunch of candles lit. So when I came in I was like, 'Wow, this is awesome.' Then he said, 'Come in, sit down because I need to talk to you.'" He then got down on one knee and proposed.

But despite the couple's happiness...

Fans aren't feeling the same way, with many slamming Dog as heartless for moving on so quickly. Did someone say rebound?

And this weekend, he only added fuel to the flames.

Amid all his Instagram posts about his engagement to Francie, Dog decided to pay homage to his late wife on Mother's Day.

He shared this photo of Beth of the day dedicated to all moms, writing:

"Mother’s Day 2018 !!! Love you miss you Beth."

And this photo, where a visibly thinner-looking Beth smiles with her daughter-in-law, Jamie.

He captioned this post: "I am DOG Chapman chiracahua Apache The best Bounty Hunter in the world I am the husband of Beth Chapman And I miss her so much"

While it's perfectly normal and healthy for people to remember their lost loved ones...

Many have raised eyebrows at Dog calling himself Beth's husband so soon after proposing to Francie. "This should of been Beth's day only so sad you had the nerve to post his gf/wife in these photos rip."

And others are even calling the reality star "two faced" for having the nerve to remarry.

One Facebook user wrote: "Absolutely two faced that is disgusting for how he was saying there will never be anyone else and promised Beth he would never marry makes me so angry."

It seems that Dog may never catch a break.
