Story
Bella is big and beautiful with a personality to match. This six-year-old mastiff mix girl adores people, snuggles, pets, and attention. She is spayed and up-to-date on all her medical care and is heartworm-negative. Bella is a big girl, approximately 65 pounds, so while she is very good with people, she would be best with older kids who can keep up with her size. She is house-trained, and a fenced yard would be best since Bella is a large dog and likes to play. Bella likes her people so much she doesn't want to share and would do best as the only dog in her home. To meet Bella, visit istodaymydayrescue.org to fill out an application. Her adoption fee is $100.

Story
This big handsome boy is Papa Bear. He recently went into a foster home where in just a few days we learned some great things about him! Papa Bear is child friendly! He has been very gentle and good with kids. He is also dog friendly though he may prefer a dog friendly with an energy level similar to his. He was great in playgroup at the shelter, with a gentle/dainty play style. He was even labeled as a "helper dog" due to his chill attitude while around canine companions. He was shy in his foster home at first, but after a day of decompressing from shelter life and getting comfortable with his new surroundings, his playful side came out. His foster mom said that "Papa Bear is literally a gentle giant who just wants love." If you're looking for a friendly, gentle and chill companion, Papa Bear might be your guy! Please consider opening your home as a foster to help us learn more about our pups! For anyone looking for a lost pet or considering adoption or fostering, we encourage you to make regular visits to the shelter. Please note that this website is updated every 24 hours and may not include all the animals available at CARE STL. If you are interested in a specific dog, such as (name of dog), we invite you to stop by the CARE STL Adoption Center located at 2700 Walnut Pl, 63103.

Story
Rita is a gentle giant that desperately wants a family to call her own. She can be shy meeting strangers, but she bonds very deeply with her people. She appears to be a guardian dog breed, perhaps Cane Corso and/or Great Dane, and weighs about 80 pounds. When outdoors Rita can be gregarious and outgoing with new people, but indoors she has been more shy toward strangers and has shown the desire to protect her people. Rita has lived in a house, including with another dog. She is affectionate, playful, smart, and very treat-motivated. Rita is a true gem for the right home!

Story
Meet Daisy!Daisy is a 1-year-old, 65-pound Mastiff mix with a heart as big as her paws! Rescued as a stray in poor condition, Daisy has been thriving in her foster home and steadily gaining weight. She’s blossomed into a sweet, loving girl who adores bedtime cuddles and following her humans everywhere—they’ll never be alone with her around!Still a playful pup, Daisy has plenty of energy and is house trained and still learning the ropes of training like not jumping on you in excitement. She’s a smart cookie and eager to please, so with patience and consistency, she’ll become an amazing companion. Daisy loves playing with bigger, higher-energy dogs, like her foster family’s huskies, and has shown promise around cats. While she’s still learning to respect feline boundaries, she’s making great progress.Watching Daisy discover toys and grow into her happy, playful self is nothing short of heartwarming. She’s ready to bring her big heart and loyal spirit into a forever home that will love her unconditionally. Could Daisy be your perfect match?IMPORTANT: Please read all below, especially if you live outside of Texas, which is where our rescue is located.Apply to adopt on our website: https://www.charmingpetrescue.org/adoptAll of our animals are spayed/neutered, microchipped, and up to date on shots.ALL of our animals are located in Boerne, TX, but transport after adoption is available to other states for a $300 fee for dogs or an additional fee varying by location for cats. If you are seeing our pets posted in your state, that's because you live near a transport stop, they are not currently at that location. Petfinder lists our pets as 'Out of Town' pets at other locations, and Adopt-a-Pet lists our location as a Transport stop. Those are currently the only options they offer to make this clear, so we put this description we've put at the bottom to explain it. You can read more about transport here: www.charmingpetrescue.org/transportWe understand transport is not an option for everyone, but we offer it at the cost we pay the transport company for those who wish to adopt from us.December 4, 2024, 3:44 pm

Story
?? Meet Bruce! ?? Bruce is a 3-year-old Mastiff who was brought to VSS after being hit by a car. The Veterinary hospital brought him to PAC for help on 11/29/24. Bruce had infected wounds on his back feet, but he`s on the mend and ready for his forever home. Bruce is potty trained and walks well on a leash once his initial excitement goes down and he goes potty. He’s very friendly with everyone he meets and absolutely loves belly rubs! Bruce doesn’t mind having his paws, ears, or tail touched. He’s a chill dog with a mellow personality, treat-motivated, and takes treats gently. Bruce is a go-with-the-flow kind of dog who will do anything for love!When staff introduced Bruce to a cat, he couldn’t care less about the cats. Even when a cat hissed at him, he just walked away, showing no interest. We think Bruce would do well with cats. We also tested Bruce with Kabob, and they matched each other`s calm energy perfectly. Bruce was friendly but not over the top, making him a great fit with other dogs.Could Bruce be the perfect addition to your family? Come meet him today and see if he’s the right fit for your home! ????#AdoptBruce #Mastiff #ForeverHomeNeeded #AdoptDontShop

We are about as adorable as it gets. We are a mix of St. Bernard/Aussie and Coonhound. We will be big, loveable family members. Won't you take one of us home with you?

For potential adopters in those areas, we can do a virtual visit using FaceTime or another app. Just request an appointment using the same link, but note that you want the visit to be virtual. We will call you at the time of the visit once it is confirmed.
