25. Mabel

Adult (6 years) · Female · Redbone Coonhound / Mixed (short coat) · 30 mi from O'Fallon

Mabel is a soft and gentle soul. She is not your typical hound. She is not exuberant or naughty. She is not the class clown. Instead, Mabel is a wallflower, trying her hardest to bloom.

Mabel was originally living as a stray in southern Missouri, periodically showing up on local farms. After months on the run, someone was able to catch her and she was taken in by a kind family. Mabel retreated to their basement, where she stayed for the next 2 years, interacting with them minimally. While they loved her very much, they knew she deserved more than they could give her and they reached out to us.

Read more about Mabel

Mabel currently lives in a home with two other dogs and two young children. It's pretty clear that Mabel has no idea how to be a loved member of the family, though her foster home is working diligently on teaching her. If left to her own devices, Mabel will spend all of her time alone. Her foster family is slowly encouraging Mabel to spend time near everyone else, though it will not happen overnight. Mabel has learned that solitude is safety, so she has a lot of new experiences ahead of her. She does enjoy gentle pets, kind voices and walks (it's when she's her most confident self). She has started wagging her tail more and more, and likes lifting up her paw to ask for pets. She is potty trained and crate trained, though she has never destroyed anything when left out alone. While Mabel is around 70 pounds currently, she has quite a bit to lose and is working hard on slimming down.

Her ideal family would be someone with a quiet home and a bucket full of patience. She'd thrive with someone who will continue to gently push her to be part of the family and not let her isolate one hundred percent of the time. She enjoys the company of other calm dogs and would likely do well with cats. She's gentle with the kids in her foster home, and would do fine with other respectful kiddos. A fenced in yard would be a huge plus, and she'd love a family who will take her on regular walks.

She may take some work, but the reward will be worth it.

Adult (10 years) · Male · German Shepherd Dog / Australian Cattle Dog/Blue Heeler / Mixed (medium coat) · 24 mi from O'Fallon

This sweet boy was adopted from us as a puppy in 2016 and spent his entire life with a family. Sadly, we were recently notified that he was found in a known dumping area, where residents caught him on camera at night being chased by coyotes. Thankfully, a wonderful person stepped in to save him and immediately contacted us because his microchip was still registered with our rescue. We went and got him right away, and he has been resting and doing wonderfully in his foster home! We contacted his original adopter, who let us know they could no longer care for him and did not want him back. And that's okay, because we made Raylan a promise: His next family will be his FOREVER family!

Now, let's talk about this amazing gentleman!

We found the answer to the question, "Who is the goodest of good boys?" And it's THIS sweet guy, Raylan!

We believe Raylan is a 50lb German Shepherd/Cattle Dog mix, so he's got plenty of love, affection, and a desire to keep an eye on what you're doing throughout the day. At 10 years young, his wild and crazy days are behind him, and he's ready for an easygoing, loving home where he can enjoy the good life. Think cozy naps, leisurely days, companionship, and lots of love!

A few things to love about Raylan: Good with other dogs, not been cat tested, Housebroken, Knows several commands, Not destructive when left unsupervised. Can be a little vocal so not a fit for an apartment. Sweet, mature, and an all-around GOOD BOY!

Who wants to open their heart and home to this sweet old man? He deserves a soft place to land and a family who will love him FOREVER!

Honeysuckle has had a rough start in life. She was a stray who was picked up by animal control. She will need a patient family to continue her progress

Honey is approximately 6 months old. While she’s still wary of situations, food will overcome her fear. She’s very food motivated and will sit in your lap if she thinks she can look pitiful enough for you to give her a bite

She’s still unsure in new situations. She’s hasn’t had much socialization.

Honey will require a securely fenced yard. Another confident dog in the home is required to help her figure out how to be a dog

28. Margarita

Adult · Female · Jack Russell Terrier / Mixed (short coat) · 5 mi from O'Fallon

Margarita is a sweet, shy cautious introverted young lady who is full of joy and love once she is settled and trust you.
We are unsure of her history as she came to rescue from someone who had just gotten her from another situation.
She doesnt like loud noises or fast sudden movements, and will take a while to warm up to people. Once she does accept you she likes to play and get loves. She Loves Loves LOVES food and treats.
She is more comfortable and happy with dogs her size then people. She does ok with cats, she likes to try and play chase with them, so if the cat is open to 4 legged games. Her current bestie is a poddle mix and they run and play it, wrestle with each other, use the house and yard as a race track, steal toys from each other and generally just bring joy and mayhem together.
She does great in the car but is slow to learn the leash, outside her space is a big scary place so patience and a fully fenced in yard is a must.

Adopting a dog in O'Fallon

Most rescues ask you to fill in an application, meet the dog, and pay an adoption fee that usually covers spaying or neutering, vaccinations and a microchip. Many are foster-based, so you'll often meet your dog in a volunteer's home rather than a shelter.

Senior dogs are often the calmest companions and the slowest to find homes. If you'd like a settled, affectionate dog, ask the rescues about their older residents.

Puppies go quickly, so if you've fallen for one, contact the rescue soon. Ask how big they're expected to grow, and plan for plenty of house-training and training in the first few months.
