Side-by-side rescue photos shared online are showing animal lovers just how quickly a dog's life can change.
Here's what to know
An individual who witnessed a dog being attacked shared images from before and after his adoption.
The photos were posted to Reddit's r/BeforeNAfterAdoption community.

In the first image, the dog is shown dirty, with its eyes closed, bite marks on his face, and with what appeared to be a broken foot. In the second picture, taken 14 days later, the pup already looks markedly brighter, safer, and more at ease.
The top comment described the before-and-after transformation as "a big glow up," to which the OP responded, "He has that smile on his face all the time."
Another commenter asked about the attack, writing, "What do you think he was attacked by?" The OP responded to this comment too, saying, "I saw the attack, it was [by a] 3 times smaller dog. I thought they were playing at first, because he didn't even try to defend at all."
What makes this transformation especially notable is how much appears to have changed in such a brief window.
Of course, not every rescue story unfolds this quickly. Some animals need surgery, extended rehabilitation, medication, or behavioral support before they begin to stabilize. But even when a full recovery takes much longer, early intervention can make an enormous difference.
What can be done?
Acting quickly matters when an injured animal is found. If you come across a hurt stray, contacting a veterinarian, local shelter, rescue group, or animal control agency can help get that animal safely evaluated.
An injured animal may be frightened or in pain, which can make even a gentle dog react unpredictably. In many cases, the safest move is to keep a respectful distance while waiting for trained help, unless the animal is in immediate danger.
People who want to help beyond a single encounter can also support local rescues through fostering, donations, transport help, or adoption. Medical fosters in particular can give recovering animals the quiet environment they need between vet visits.
Sometimes the difference between a devastating "before" and a hopeful "after" is just a couple of weeks of care and protection.

A dog can look in terrible shape at first, then change quickly with treatment and a safe place to recover. These articles show just that.
