However, please keep in mind that we rarely know the genetic background of the animals we rescue and, as such, we cannot guarantee the exact breed combinations found within this dog. However, we do not know his/her actual genetic makeup. Just know that this dog is probably a variety of several different breeds that have combined to create one very amazing and unique animal.

Meet Finrir (Finn)! Finrir, affectionately known as Finn, is ready to charm his way into your heart and home! About Finn: Finn is an 85 lb Mastiff mix with a heart as big as his size. He's a gentle giant who thrives on one-on-one attention and would love to be the center of your universe! Despite his size, Finn is a total softie. He's non-destructive and a pro at taking his medicine with ease. While Finn prefers to be the only fur baby in the house due to some dog reactivity, he'll fill your home with enough love to make up for it! What Finn Needs: A loving family who understands his need to be the only pet. Plenty of space for him to stretch out and relax. Someone who enjoys leisurely strolls because Finn walks like a true gentleman on the leash! Interested in Adopting? If you're ready to give Finn the forever home he deserves, reach out to Center for Animal Rescue and Enrichment of St. Louis - CARE STL Let's find this big guy his perfect match! Help spread the word by sharing this post with friends and family. Together, we can help Finn find his happily ever after! #AdoptDontShop #FosterDog

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
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. 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.May 5, 2025, 11:29 am
