Story
Atlas is a sensitive soul who just needs the right environment to shine—and once he feels safe, his true personality starts to emerge. He is very food motivated, dog friendly, and just beginning to learn how to play and enjoy affection. Atlas would truly benefit from a quiet, patient home or foster placement where he can decompress at his own pace and continue gaining confidence through gentle, positive interaction.

Story
He is a good dog(English mastiff/ border collie). I got him from a local police officer whose dog had pups. He is 9 years old and loves attention. He does not do good with adult animals. He does better if they are introduced when they are small and he still needs some correction. He is good with kids but he is not aware of his size and can be a little rough for small children. Someone who can provide him a loving home with care and let him play outside when he wants but not leaving him outdoors forever. He’s hyper and lazy all in one. He learned everything he knows from a Jack Russell. I am separating from my significant other and will be downsizing to an apartment and can not take him as he is to large and it would be unfair to keep him in an apartment.

Story
Meet Molly! Molly is a 6-year-old Mastiff/American Bulldog mix weighing approximately 93 pounds who is looking for a calm, loving home to call her own. After spending 175 days (as of 08/17/56) in the shelter, she is ready to find the family she's been waiting for. She is now considered a Diamond Dog with adoption fee is $75. Molly is an intelligent, loyal, and deeply sensitive girl who forms strong bonds with her people. She is treat motivated, walks well on a leash, knows several basic commands, and even offers her paw for a shake. She also appears to be house trained and crate trained, making her transition into a home much easier. She would do best in a peaceful home with children 16 years of age or older or an adult only household. Molly is not compatible with female dogs but may do well with a calm, large breed male dog. A meet and greet is required for homes with a resident male dog. Molly is spayed, microchipped, heartworm negative, current on her rabies vaccination, and up to date on her basic boosters. If you're looking for a devoted companion with a gentle heart and unwavering loyalty, Molly may be the perfect addition to your family.
