I remember getting angry seeing a dog go through this before, but then finding out it was because their human developed Alzheimer's, and kept forgetting they already fed the dog. Taught me something about learning the whole story before getting angry at someone I didn't even know.

That image of her laying in the bed watching on whilst the other dog exercises... Basically my life

This inspired me to lose weight myself. After losing 100 pounds, I'm happy to say that I can scratch my ear with my foot now.

This person believed in this dog more than my parents would ever believe in me.

Okay but the fact that she’s named Bertha is hilariously cute 😂

The foster mom really saved that dog's life!

She SMILED when she scratched her ear. My heart cannot.

Bertha dressed like a unicorn is the cutest thing ever!

Bless this women’s heart cause she genuinely cared for this dog

Dear God this is the best thing I've ever seen

If Bertha can do it ,we can do it ! Go Bertha ❤️

You know full well that she appreciates your help, you gave her freedom back, top dog owner 😊❤👍

“From Fat Bertha to Fit Bertha: A Transformation of Love and Persistence” I’d read it.

I can only imagine the dogs pain in the beginning

Bertha got lucky because of your kind heart! She is lucky to have you and you her. She has a new life because of you.

Wonderful. Thank you for sharing this.

2:25 Bertha’s secret motivation to lose weight: “”I’ve got to fit into that gorgeous unicorn gown”

Seriously don’t understand how some ppl put thumbs down on story’s like this. Must really be in a bad place mentally.

awww such a cute baby

No one is making any comments about Bertha’s amazing outfits?! She clearly loves wearing them and all the attention she’s getting. Thank you for being so diligent with helping her. Bertha seems like she has a great life!

Oh how sweet she is. How great you are. She didn’t even realize she was losing. I love her very much.

I couldn't stop laughing at the part where she says, "It was hard to get Bertha to do anything, as the dog is laying on her bed watching that tall thin dog workout on the treadmill, omg, classic 00:56

"With the right person, she could have a chance" is what we should also be keeping in mind when seeing struggling children.

"bungee cord" WAIT, don't tell me, it has the properties of both rubber and cord

It was so heartbreaking to see poor Bertha trying to walk at the start of the video. So glad her foster mom did such a good job helping her shed the weight.

Wow, adopting am older dog whose obese! This woman is a gift to animals. May we all be so kind. 🐕‍🦺🐾

That type of dedication ... that is Love.

“Dog can’t stop smiling” Yeah well I can’t stop crying

The secret to any exercise and diet program, is a purple tutu, and a golden horn.

She's an old dog, and I'm happy she gets to spend her twilight years being able to have fun, not just sitting in a dog bed counting down the days.

1:13 - perfect visual representation of me trying to get through life

Love this story. Good for Bettha.

Sixty three pounds is so heavy for her she's a small dog and all that weight is hard on her legs, breathing everything, thank you so much for helping Bertha your saving her life!! Clearly she is pleased to feel better and be so loved and cared for, you are the best!!!!

"She's just so happy to be a dog.". As Bertha goes outside in pink clothes...I LOVE it😂🥰🤗

Good to see Big Bertha transform into Regular Bertha

RIP Bertha! I'm grateful you had a chance to enjoy a healthier life before passing on.❤

The woman laughing while talking about how she needed to use a bungee cord to keep the vest on the dog 😂

To think that this tiny tiny dog weighed as much as a 10 year old..

When the dog is in the pool he’s like nope I wanna rest not swim!

Thank you for saving this sweetheart ❤️ Congratulations Miss Bertha👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻...your looking Amazing🥰

I love how the woman laughs about how Bertha couldn’t fit in her life jacket.

Bertha is such a precious baby. It warms my heart to see how her life improved because of her new mom's love and care.

Almost as sad as obese children. Thanks for taking care of her.

I don’t blame the rescue dog for not stopping the smiles, I don’t think I could stop smiling if lost as much weight as she did you should be proud of yourselves

Seeing Bertha struggle like that broke my heart. I am *so* glad her foster, now forever, mom gave her that chance.

That foster mom is a legend. Definitely saved that dog's life!

2:53 that is the face that says it all, after all of the hard work put into making this dog healthy again, here you can tell that the dog felt how I felt and how many others feel after working hard to lose a ton of weight, a sense of relief and satisfaction.

What a transformation. Bless you for giving Bertha the chance to live instead of existing. Of course you adopted her, how could you not? Big hugs to you and to Bertha and her other friends.😊🙏

You can tell she's feeling so much better & is happy. God bless this lady's dedication & perseverance! 💜

"she's just so happy to be a dog" , out of context this is extremely hilarious 😂😂

My dog is pumped. And now he is going straight to the gym.

Soooo beautiful and inspiring. The best of the best people helping the helpless animals who need love and dedication.

Feeding animals to the point of obesity like this is a form of animal abuse to me

No weight loss story has ever inspired me like this!

Imagine having itches you couldn't scratch or tell anyone about for YEARS. So happy for Bertha. & what a loving woman.

Underwater treadmilling is so fricking cute I can’t.. Like the costume 🥰

Seeing the one dog exercising and Bertha in the corner sleeping is sooo relatable. 🤣

You are to be commended! You gave Bertha her life back. So grateful that there are people like you. It could not have been easy.

I would love a snap shot at 1:44 on a sweater that says "Nothings ever simple" 😂❤

This woman gave more attention/care to that dog than my parents did to me my whole life.

I LOVE this woman's sense of humor while being so caring in a serious situation.

reddit users when they overfeed their pets and call it "chonky"

Thanks for being this dogs savior

I recognize a puggle when I see one. They will literally eat anything.

Wonderful to see how much you cared about her, especially her weight. I'm impressed with her water excerise program, all Vets should have that available. 💟🐕👍🐕👏

I wonder if her original owners where elderly. I see this a lot with really old folks. Who are sick, physically and mentally and don't understand what they are doing. Glad she is better now. Overweight is just as bad as underweight for animals.

This dog will be the greatest ambassador for any weight loss program...

She is so beautiful she makes me so happy ❤❤❤

Such a precious pup, many thanks to her foster person!

63 pounds haha holy smokes. “Walked about 5 steps and said NOPE” lol sounds like myself

This is such a cute dog. Look at her smiles after she becomes healthy

I have reached heaven with this video

I feel so bad for this dog and I really hate the people that let this happen to her.

Bertha is a little darling. And the other dog on the treadmill was like the supermodel of dogs

Absolutely Awesome!! Go Bertha!!😁

I'm not crying you are!!!!

I did something similar with a cat we adopted a number if years ago. We found her at the Humane Society. It was love at first sight. We named her Louisa. Louisa was so hungry all the time. When she'd been rescued, she had been out in the cold for two weeks. We started her on dry food, and over the course of a year, she became quite heavy. Even though we had reduced the amount of food she was eating, she was still quite round. One day we took her to the Vet, and the Vet recommended canned food. So we put her on a strict diet of 1/3 can of food, twice a day. Slowly over the next several months she lost weight and became more active. She had short legs, so she couldn't jump very high. We would bring her out to the deck that was enclosed with a gate, and she loved being outside, laying in the warm sun, and chasing chipmunk down to the drain pipe. Louisa lived to the ripe old age of 23. She lived in comfort, loved all of us unconditionally, and was a very happy cat. One day we took her to the Vet, and the Vet discovered a lump. A biopsy was taken and it was cancer. We had a choice to put her on chemo or let her live another six months without the poison of chemo. We chose the latter. She did very well until about five weeks before she passed. Then she got a mouth infection. So the Vet did a cleaning, and removed infectious tissue. She came back and enjoyed another four weeks of no pain. The infection came back, and we knew she was at the end. It was evening and we took turns holding her wrapped in a soft towel. She knew she was loved. The next morning, we took her in to the Vet hospital. Before they gave her the final shot, I held her head in my hands and looked her straight in the eyes and said, "We love you and know it's your time. Send me a sign that you're all right." Then the doctor gave her the shot. She was gone within seconds. I cried, but knew it was her time. She was no longer in pain. About two days later, I was sitting watching TV, when out of the corner of my eye, I saw a silhouette of the cat race across the floor and dissapear between the two easy chairs. I knew it was Louisa. A week later, I saw her again. She was about three feet off the ground as she ran past the TV and disappeared into the wall. Another time, we were having a quiet conversation at dinner, when I heard a very soft meow down on the floor. It was Louisa letting me know she was there.

I love videos like these. This amazing woman took time out of her day to not only foster this dog but actually saved her life.

Big Bertha

Bertha got more than lucky when she met you, she got her life back. Bless you for caring.

I'm happy for the dog that it is safe now.

They never seem to dissapoint me with these hearthworming stories and animals

Thank you for all your hard work and for caring.

This dog just inspires people about life changing.

I love how committed and determined the person was to help the dog lose weight. Even thinking outside the box to help the dog be able to be mobile again.😭🙄

i love people that foster and then don't give them away so heart warming.

A triumph of surgery ❤️

Seeing how happy she is to be able to do things just warmed my heart. I'm sure there were times when she'd have been begging for treats and saying no to puppy eyes is a really hard thing to do. Congratulations Mum, you've given her a much longer, much _much_ happier life!

She looks so sore at the beginning, poor thing:(

Great job Bertha!

Thank you for not giving up on Bertha and adopting her.

Did her weight effect her legs? It appears that she still struggles to walk right 😞 Bertha is a champ, thank you for saving her ❤️

This woman gives me hope in humanity. Bless her heart

Loving a dog isn't over feeding them. Love then enough to give them the best diet and exercise. They'll be happier and love you for it.

Well done Bertha 😁👍🏻🙌🏻 you are just the cutest fur baby 😊

... "and I adopted her." Raise your hand if you *didn't* see that coming. :-)

My puggle just passed a few days ago so this actually hit me in the feels 😢

🥰💖Thank You 4 caring 😁💖💕💯💯💯💯💯🥳

Dog did better than 50% of people in America 😂

I can't believe some people could ever let their dog get to this weight in the first place. Its not "cute" its animal cruelty
