Story
Meet Siggy – Your Loyal, Loving GuardianSiggy is a gorgeous 2-year-old brindle Great Pyrenees mix weighing 82 pounds. She is incredibly sweet, especially with children of all ages (incl. rambunctious toddlers) and gets along well with other dogs in the home. True to her breed mix, Siggy is both intelligent and protective—once you’re part of her pack, she will be fiercely devoted and always have your back.As a Pyrenees, and what we believe to be a Catahoula mix, she has strong guardian instincts. She is deeply bonded to her family “pack”, and is naturally protective. She isn’t aggressive but is true to her instincts as a protector. She’s also very submissive/eager to please—she learns quickly and never needs harsh discipline to understand what’s expected of her.Siggy does have some separation anxiety, but she does fine when she has another dog around for company while her humans are away.While Siggy is incredibly affectionate with her family, she isn’t a fan of crowded public places or strangers approaching her and her “pack”. However, if given the chance to approach others on her own terms, she is gentle and sweet. She would do best in a home that understands and respects her protective nature- one that provides the proper introduction to guests, and provides enough yard space to be a mostly stay-at-home dog, where she can love on, sunbathe, and protect, her family.Commands she knows:-sit-shake-leave it-drop itIf you’re looking for a fiercely loyal, intelligent, and loving companion who will always be by your side, Siggy is the 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.

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.

Story
My name is Chap and I am a brown & black mastiff. I am a neutered male and I am 8 years old. I was transferred here from another shelter/rescue through the Ames Animal Shelter`s Third Chance program on 03/08/2025. I was left abandoned at that other shelter by my owner, and I waited at that shelter for a home for a year. I am potty trained. I am a medium energy dog and I will need an owner with some prior pet owning experience. I am a very good boy, but I`m a large guy and that requires you to have the space and accommodations for me to be comfortable. The shelter staff is not sure if I am used to being crated during the day, but I am comfortable in my kennel at the shelter. I do pull when walked on the leash and am very strong, so I`ll need a strong owner! A fenced yard would be a great way to let me exercise, but is not required. Due to my large size and tendency to boss around other creatures, the shelter staff will not place me in a home with other pets or children under 14 years old. Being in my golden years, I think I`ve earned the right to be the center of your world in my new home!All dogs are tested for heartworms and given flea preventatives. They are also tested for intestinal parasites and receive routine dewormings. Dogs are vaccinated against distemper, rabies, and bordetella, spayed/neutered before adoption, and have a microchip. Adoption fees include the initial automated registration of the microchip at the time of adoption.
