Story

It absolutely breaks my heart but after a lot of thought, training efforts, and difficult conversations, we have made the decision to rehome Maple. For the past 3 years, our dogs were the best of friends. Unfortunately, things have changed in the past few months, and despite time and training, they have now gotten into 3 very serious fights with each other. At this point, we have to put everyone’s safety and wellbeing first.Maple is a sweet, affectionate, cuddle loving dog who loves every human she meets! She loves to play fetch and walks great on leash. She will be a friend for lifeMaple has shown aggression toward our other dog Bella, but has historically gotten along with dogs her whole life. She has two best friends that she hangs out with regularly. We believe she would do best as the only pet in a loving household where she can thrive and get the attention she deserve.This is not a decision we made lightly, and we are committed to finding the right fit — not just the fastest one.

Story

Hi, my name is Bella 💗 I’m a sweet, shy girl who is still learning that the world can be a safe and gentle place. I may be timid at first, but once I feel comfortable, I show my loving and loyal heart. I do best in a calm, patient home where I can move at my own pace and build trust slowly. Soft voices, cozy naps, and kind humans mean everything to me. I’m an older gal with lots of love to give, and I’m hoping for someone who sees past my shyness and gives me the chance I deserve. If you’re looking for a gentle companion who will quietly steal your heart, I might be your girl. 🐾

Story

Blue is a wonderful pup. He loves love, snuggles, kisses and play time. We got him from my daughter who couldn't take care of him in her small place and having a new born. Blue loves the baby always giving him kisses. We do not have the time to fully train or play with him as he deserves. He is fully potty trained. Knows how to use doggy door. He is a gentle giant. I want him to go to someone who can give him all these things and love him as he so deserves. He is a pitty mix not sure with what. Maybe lab. He is about 10 months. Not quite sure as he was abandoned as a puppy.
