Lavender is such a sweet soul. She has this incredible ability to connect with everyone, never seeing a stranger in her path. When you meet her, you`ll be welcomed with an abundance of joyful wiggles that can instantly brighten your day. She’s great with other dogs, always eager to make new friends.

Story
You can fill out an adoption application online on our official website.Meet Zay. She’s a 2 year old mastiff mix with the squishiest face ever (she’s also the aster of RBF). Zay came to us completely shut down, defeated, in a constant state of fear. After lots of confidence training, she has come out of her shell and absolutely loves to play with dogs, totally ignores cats and even enjoys taking treats and pets from humans. Zay is potty trained, crate trained and has been through several weeks of obedience training in addition to confidence building. She’ll come with training for her new family and the tools that have helped her “dog”. Zay REQUIRES at least one other dog living in home with her; we are not making exceptions as the trainer has advised us this is a necessity for her.Visit this organization's web site to see any additional information available about this pet. All of our dogs are spayed or neutered, up to date on age appropriate vaccinations, microchipped and if over 6 months of age, heartworm tested and on heartworm preventative in their foster home. We require an approved application to meet any of our dogs. We do not have a shelter location and will not arrange a meeting without an approved application. We strive to make sure the bios provided for our dogs are complete and accurate; we do understand that mistakes happen, however, so if you absolutely cannot find the answer to your question in the dog's bio, you can contact us for more information. We require a home visit for each dog we adopt out, so we adopt within a 2 hour radius of Dayton, OH. If you are outside of this radius, we encourage you to contact your local rescue or shelter.   March 27, 2025, 7:28 pm

**WE ARE SUPER MUTTS - PLEASE SEE DNA RESULTS PRIOR TO APPLYING** Hi, my name is Perdita and I am one of Lilith's little demons. Luckily MVPC swooped in and rescued us from the shelter before we were even a week old! Let me tell you, that is no place for puppies. My litter may be a mix of a lot of different breeds (see our DNA in the pics) but I think that's what makes us the best! I am one of the smaller pups but I am bold and a mover & a shaker. I am super spunky, brave and high energy. I also love to play with my siblings, toys and to be with my people - I'm a cuddler. I am super cute and pretty darn smart! Please understand that while I am doing well on potty and crate training, I will have accidents and may whine some as I adjust to my new schedule and family. ADOPTION FEE: $350 (All MVPC dogs are heartworm-tested and on prevention, completely vetted, spayed/neutered, microchipped, crate-trained and house-trained) ADOPTER: Dog experience BIRTHDAY: 10/17/2024 FENCE: Required (an electric fence is not an acceptable form of containment) DOG FRIENDLY: Yes DOGS IN HOME: Required CATS: Unknown CHILDREN: Yes, 8 and over **Again, WE ARE SUPER MUTTS - PLEASE SEE DNA RESULTS PRIOR TO APPLYING** I AM READY TO GO HOME - If you are approved to be my new family, a hold fee of $100 is required and will be applied to the full adoption fee of $350 when MVPC comes to visit your house with me! ***WE DO NOT HOLD DOGS.

Story
Hello interested Adopter. My name is Lilith, but my foster fam always calls me "Momma". You see back in October '24 a foster said "Yes" to not only me...but my week old babies as well! MVPC saved our lives. I had wonky legs at intake, but everyone hoped and thought that crate rest with my babies would help. Well, come to find out, I'm just wonky. I don't remember how old I am, but I did have these babies later in life. After visiting the vet it was determined that I have hip dysplasia in the back and a wonky elbow in the front. This combination makes amputation of my front leg impossible. I will always need to remain on joint supplements. MVPC sees that I am a happy girl who has lots of love to give. I seem to be pain free for now, so I am now up for adoption. I would do best with a family who is used to senior dog issues. I am currently fostered in a home with male and female dogs of all shapes, sizes and energy levels. After years of neglect and countless litters of puppies, I'm looking for a sweet retirement home. I can't wait to meet you! ADOPTION FEE: $300 (All MVPC dogs are heartworm-tested and on prevention, completely vetted, spayed/neutered, microchipped, crate-trained and house-trained) ADOPTER: Dog experience BIRTHDAY: est. 10/17/2015 FENCE: Required (an electric fence is not an acceptable form of containment) DOG FRIENDLY: Yes DOGS IN HOME: Required CATS: Unknown CHILDREN: Yes, 8 and over I AM READY TO GO HOME - If you are approved to be my new family, a hold fee of $100 is required and will be applied to the full adoption fee of $300 when MVPC comes to visit your house with me! ***WE DO NOT HOLD DOGS.

Story
Looking for love and a great home. Garnet is a super sweet big lug of a mastiff.  Garnets house burnt down December 27, 2022 and he was so badly burned no one was sure if we could save him.  We felt really bad for him and his owner, so we cared for Garnet while getting him well. It took 6 months of horrible pain stacking medical Care. He is great now but he will be scared for life but looks great.  His owner rebuilt and wanted him back.  Now she has decided it would be better for him for us to find him a loving home.  He is truely a very special guy.   Garnets date of birth September 17, 2020. Garnet is fawn with a black mask.  He is up to date on vaccines, on heartworm prevention, micro chipped with Home Again  he is well enough to be neutered and that happens on 11-28-23. We do not have any pictures of his after he was healed as good as he gets. We lost all  the pictures but we have pictures of his long six months of Recovery.  If you have room in your heart and home for this sweet boy or any of our other wonderful, beautiful babies please email Miracle House Animal Rescue and we will send you our adoption questionnaire: miraclehouserescue@gmail.com.

Story
Meet Angel, she is a 4 year old mastiff and she is looking for love. Angel is spayed, up to date in vaccine, on heartworm prevention and Micro chipped with Home Again. After fire destroyed Angel's and Garnet's home on 12-27-22, Angel ran into the woods and was lost for 7 days. Their own had just lost everything and ask if we could save and care for them until she was able to have a place for them. On 12-29-22 I got Garnet to foster in my home. On 1-5-23 Debbie and Dan were kind enough to foster Angel in their home. After 6 months Garnet was finally well enough and their owner now had a place for them and took them back home. Soon after their owner decided to give us Garnet to us find him a great home and now she is giving us Angel to find her a great home. After the fire while scared and lost poor Angel clearly did not find food or water, she was so weak she could barely raise her head. As soon as we got Angel we took her right to our vets office., where Angel got a good exam and CBC/chem. Fortunately, her blood work was all good. She needs to be fed several smaller meals each day, to let her body adjust and get the pounds back on. She was covered in ticks and was treated for that too. Angel missed her monthly heartworm prevention on the first of the month, but it was close enough that she got it today. One of her eyes was treated for a minor injury. A few days after we got her she got sick and tested positive for lyme disease. Angel was treated for the lyne disease and did great. We can't believe she was not burnt like poor Garnet but thank to Garnet for putting her behind him and protecting her. Of corse Angel is fine now. The pictures are old pictures of Angel the day we got her, when we were in the garage at our vets office picking ticks off of her. 2 pictures from Angel's mother. Will will get new pictures of Angel as soon as she is here. We are 100% all volunteer, 501(c)3 charity. We are a foster based Rescue and we work by appointment only after you are approved. Located just east of Cincinnati in Clermont, Brown and Adam Counties. miraclehouserescue@gmail.com

Story
Congo is an African Boerboel He’s very well trained and great with people. He does scare people because of his size and bark, very big and loud. which is good for him being a protector. But he wouldn’t hurt a flee. He’s a big baby. He barks when someone comes to the door or in the house he doesn’t know but chills out very quick once you’re in the door. We are rehoming him due to a move. My kids as well as myself are heartbroken. I just need a loving place for him.
