Story

Drool is Cool!!! Clyde is an adorable giant who is as sweet as he is big. Not really sure of his mix so best guess mastiff/Great Dane. He could totally be a pittie chihuahua but either way he is awesome!! Clyde is extremely dog and people friendly. He is respectful of the older dogs, gentle with the little puppies and a bull in a china shop with the age appropriate (smaller size) heathens that play with him. Clyde was found as a stray on the reservation and was very skinny. His foster family is working diligently to fatten him up (and he loves all food and treats)!! He did not seem to be familiar with different flooring and likely was never indoors but he is a fan now! He uses the doggie door almost all the time )but has to duck as it isn't for such a tall guy). He is gentle on a leash and knows how to sit and shake. He is a leaner and by that we mean he will lean into you. He loves to be touching but isn't overall needy. We have yet to hear him bark and he does well by himself outside in a kennel. He prefers to be in the house and hang with his people (and has discovered a love for couches and dog beds). When he goes outside he initially has the zoomies and gallops like a gangly colt. After a lap or two around the yard he is ready to chill out. Clyde will likely not be a hiking or running buddy but enjoys a nice stroll. This goofy guy is fostered in Colorado Springs and is ready for his forever life. If drool offends you he isn't your guy (not an all the time thing but definitely after food and water). Clyde is neutered, vaccinated, wormed and microchipped. ##2394098##

Story

Meet Sabrina, a gentle 6-year-old Mastiff mix who’s in need of a special forever home. Sabrina is living with mast cell tumors (MCT) due to cancer and is currently on medication to keep her as comfortable as possible. She requires a loving home that is prepared to offer her hospice care and a peaceful environment. Sabrina can be shy with new people and may give a warning growl or snap if approached when she’s not ready. However, once she builds trust, she becomes deeply affectionate and very attached to her people. She gets along well with mellow dogs and will thrive in a calm household where she can feel safe and loved. If you have a compassionate heart and are ready to provide a supportive and caring home for a special dog like Sabrina, you’ll find a loyal and loving companion in her.

Meet Nala, a 6-month-old Mastiff pup with a heart full of love and energy to spare! This sweet and playful girl is always ready for an adventure, whether it`s a game of fetch or a romp in the yard. Nala is growing fast and learning quickly, and she thrives in an environment where she can stay active and engaged. Because of her size and energy level, she’d do best in a home with older children who can keep up with her fun-loving spirit. She has met another dog here at the shelter and seemed interested in play, so bring your dog in to see if they will be best friends. If you’re looking for a loyal companion with a goofy side and lots of love to give, Nala might just be your perfect match!What I Need In a Home:* Older children recommended
