GPMR does not have a shelter. All of our dogs are kept in loving foster homes. We must have a completed adoption application on file before meeting any of our mastiffs.
GPMR adopts to the states of Oklahoma, Texas, Kansas, Arkansas, Missouri, Louisiana and parts of Colorado.
!!!Any mastiffs being adopted out of the state of Oklahoma require a health certificate to be paid for by the adopter!!!
Meet Mirabelle, the miracle! This amazing girl was surrendered to local animal control from a neglect situation. Sadly she recently had puppies that were given away. She was only 75 lbs and should be double that weight. Thankfully the shelter reached out for rescue and we picked her up yesterday (you can see her being hugged by shelter staff in one of the photos).
Despite the hard life she's clearly had, this girl has nothing but love to give. She loves people and has done great with the other dogs at her foster home. We're still working on house breaking as she never lived indoors before. She will use a potty pad and is being trained to use a doggy door. In typical velcro Mastiff style, she wants to be with her people always. She is somewhere between 4 - 6 years old. We don't have an exact age and it's difficult to estimate age on dogs in this horrible condition.
At Mirabelle's first vet vist with us, she already gained 14 lbs in 2 weeks, speaking to the level of starvation she was suffering. She was treated for intestinal parasites. Thankfully she was heartworm negative but tested positive for a tick disease called Ehrlichia which is common to see in our rescues. She's got a long road ahead of her to get back to health! We will post updates with her progress.
Mirabelle will be on medical hold until she's healthy enough for adoption.
