Story
Ivy the Mastiff is an approx 1-year-old lovely girl. She came in with an injury to her right hind foot. Somehow she lost the toes of that foot. They felt that she needed to have the leg amputated but one of our best vets feels that we can save her foot. She came to us from Oklahoma and we know virtually nothing about her past, but she is such an amazing dog. I adore her. She is sweet, gentle, friendly, goofy, and she loves her foster mom's little 21# male dog. She is active despite her injury. She likes to spend time out in the yard and also loves to snuggle on the couch. She sleeps on a dog bed in my room. She is house-trained and walks on a leash, though she tends to want to lean on you as you walk. She is a beautiful cream color brindled dog. Apply for Ivy to come meet her in Berthoud. I have to warn you...you're gonna fall in love...

Story
Meet Alfredo! This gentle soul was rescued by a kind stranger who lured him in with—you guessed it—chicken alfredo. Now he’s looking for a loving home where he can lean into pets and soak up the affection he’s always deserved. Alfredo may need a little time to adjust to his new surroundings, and he prefers slow, respectful introductions to other dogs. If you’re ready to give a sweet boy a second chance, Alfredo just might be the perfect dish.
