Mocha is the sweetest pup! She loves to be loved! She is a high energy puppy and with current health issues going on we cannot give her the care that she needs.

She has been doing good with potty training but does have occasional accidents when I am at work, or if she gets to excited. Her estimated birthday is august 1. She was adopted at the humane society as at 13-15 weeks old. The adoption fee is to ensure she goes to a good home and she will be sent with her current food and her favorite toys.

Story
Meet Roscoe, he was found as a stray. He is very friendly and gets along with other dogs. the nice family that found him can’t keep him but is fostering him until his forever family can be found. They think he’s young, like under 2 yrs old. He’s house broke and very sweet. Plays with their poodle like they are best friends. He would need a fenced yard because he’s a critter chaser. He’s been on car rides and on walks at the park.   If you can open your home to this sweet boy, please text Nanci at 314-574-4052. Serious inquiries only. note: this is a courtesy post. Roscoe is not an All Paws Rescue dog. September 24, 2025, 12:13 pm

Spayed or Neutered,
Story
Meet Dexter! This sweet Boxer mix is as affectionate as they come—his favorite place is right in your lap. Dexter loves car rides, playing fetch, splashing in the water, and being close to his people. He has the typical boxer energy and boxer traits. He’s potty trained, does well in his crate, and sleeps through the night. Dexter already knows sit, down, place, and come—and with his love of treats, he’s eager to keep learning! He’s still practicing leash manners (sometimes he forgets and pulls), but with patience he’ll nail it in no time. He would do best in a home without little kids. If you’re looking for a snuggly best friend with tons of potential, Dexter’s your guy!!
