Adopting a pet can result in huge transformations, for animals and their humans alike. In a SubReddit called /r/BeforeNAfterAdoption, adoptive pet owners get together to share how much their pet has changed. Most animals have grown healthier and stronger—others feel so comfortable in their new digs, they have no qualms about showing off just how silly they can be.

Lucy was malnourished when she was adopted and had an array of other health problems too. It took her a while to adjust to life with her new owners, but she's now happy and healthy. Her owner posted a whole album if you want to check out her progress for yourself.

Found in New York City, Walker had a rough time before being adopted. He had some health problems at first, but once he got better he quickly adjusted to his new home. He likes playing with Bruno, the other dog of the family, and spending time outside.

6. Herschel

Herschel was taken in by a friend of his former owner, who tried to take him to a shelter. He was turned away because he was deemed too old to be adopted out. Today he's happy, healthy, and looking extra-distinguished.

Like many pound dogs, Peach was found wandering around with a few infections. Luckily, her new owners have taken great care of her and nursed her back to health.

20. Lucy

The shelter this dog was adopted from believed that she had been hit by a car, and her medical bills made it difficult for her to get adopted. That didn't stop her current owners from taking her in and getting her the treatment she needed.

21. Bubba

Named after golfer Bubba Watson, dog Bubba was adopted from a foster group who found him tied to a pole. While he's still hesitant to trust people, he's doing much better and even has a new favorite sports team.

22. Bingo

Bingo wasn't properly taken care by his first owners, which led to him having to get one of his legs amputated. But that hasn't stopped him from loving his new friends and owners with all his heart. Bingo is doing much better in his new home and now loves food and playing with everyone he meets.
