In just a week, Brewster has gained six pounds.

The boxer was just 25 lbs. when he was brought by his owner to an animal shelter last week— dogs like him are typically more than twice that size.

On Monday, there was justice for Brewster: the dog’s owner Anthony Esteves, 25, was arrested on felony animal cruelty charges for allegedly depriving the dog of food, water and veterinary care between July 1 and Oct. 13, the New York Daily News reports.

Brewster may have been near death and unable to walk when he came into the shelter’s care, but he isn’t letting that get him down. He’s recovering in a Manhattan foster home and having a ball with his new canine playmate, Benjamin.

“His temperament is amazing,” says his foster mom, Dr. Amy Swift, of the Adopt a Boxer Rescue. “He’s amazing with my 13-month-old daughter and great with everyone on the street.”

Despite what he’s been through, the pup has “zero aggression,” Swift tells PEOPLE. “You literally couldn’t tell that this dog had gone through anything rough in his entire life.”

As adoption applications pour in for Brewster, the rescue is giving credit to police for doing right by the dog. “Huge thanks to the NYPD for jumping on this so quickly and being so passionate!” reads a message on the rescue’s Facebook page celebrating the arrest.

It will be several weeks before Brewster is ready to be adopted, the rescue says. To apply to adopt him, or so many others like him who need homes, visit Adopt a Boxer Rescue’s website and click on the adopt/foster link at the top. Click here to donate to the Adopt a Boxer Rescue.
