16. 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!

Read more about Raylan

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!

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.

21. Brent

Adult (9 months) · Male · American Staffordshire Terrier / Mixed (short coat) · 30 mi from O'Fallon

This is Brent and he's exactly who you think he is based on his name. Brent is an all-American dude with a love for football, beer and finance (probably). Brent is blissfully clueless that his two braincells are working overtime, and that's exactly how he likes it.

Brent originally came into the local animal control as a stray and quickly became a volunteer favorite. As time went on, Brent became more and more stressed and landed himself on the euthanasia list. Luckily for him, he had plenty of people who adored him and advocated for him. He caught his fosters eye and the rest is history.

Read more about Brent

Brent currently lives in a foster home with two female dogs and two young children. We think he'd love a dog to play with, but his canine foster siblings aren't the playing type, so he's great at coexisting with them. He's loving with his human foster siblings, and absolutely ADORES cuddling. If it was up to Brent, he'd spend his whole life snuggling with his people. Brent is a happy guy and exudes joy.

Brent can usually be found playing with toys, pretending he's a beagle and looking for food, or snuggling with his foster family. He knows "sit", "lay down" and is potty and crate trained (though admittedly he is not a fan of being crated long periods). Brent very much enjoys walks and would love to explore the outdoors with his new family. Brent has never met a stranger he didn't like (though periodically they've wished he was less enthusiastic about meeting them).

In Brent's ideal home, he'd have a fenced-in yard, be allowed on the furniture (see: cuddling), have parents that are home more than not, have someone who enjoys daily walks and have a family who is ok continuing his training. He'd be happy with or without another dog and with or without kids.

Whoever ends up with his guy is one lucky family.

Please note that Brent has recently been through heartworm treatment. He has to be kept on restricted activity until November 20 (which basically just means he has to keep his heartrate down). His foster mom is more than happy to tell you more about what this requires!

She is crate trained but doesn't need to be crated.

She is housebroke and walks well on a leash.

She was owned at one time but was kicked out of the home because she kept getting pregnant and the man got another dog, so she was left outside and had her last litter which we took in and we spayed her and as soon as we had a foster for her, she came into our rescue.

She was very shy at first but now she wants belly rubs and likes laying on the couch. She is even starting to play. She seems to like female dogs better than males that get in her face. She is going to be a great family pet, not sure about little kids though.

Adult (1 year 7 months) · Male · Boxer / Mixed (short coat) · 30 mi from O'Fallon

Meet Pablo!

Pablo is a very sweet Boxer mix who has already come a long way. He was rescued from a heartbreaking situation with more than 190 dogs, and his skin was in rough shape. Thankfully, with love and care, his skin has cleared up beautifully!

Pablo is very shy, especially in new situations, and he may not be the dog who immediately wins you over when you first meet him. But underneath that nervous exterior is a gentle, loving boy just waiting to feel safe.

Pablo needs an adopter with an extra-big heart, patience, and a willingness to let him blossom at his own pace. He would do best in a calm home with another friendly dog to help show him the ropes and give him confidence.

Pablo may take a little time to come out of his shell, but watching him learn to trust and love is going to be incredibly rewarding. He loves to give kisses as he starts to feel

Why adopt an adult dog in O'Fallon

An adult dog's personality is fully formed, so the rescue can tell you how they are with people, other pets and busy households. Many have lived in foster homes and are already house-trained.

Grown dogs need less supervision than puppies and often know the basics, like sitting and walking on a leash, which suits people who work or have young children.
