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.

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.

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.February 6, 2025, 10:16 pm
