Story
Zeus is a big boy with lots of love to give, so if you`re looking for a 100 pound lap dog, look no further! Zeus is looking to be the center of attention in his next home and not share the spotlight with other animals, so we are requiring he go to a home without cats or other dogs. And while he`s done well with kids, his size makes it easy for him to accidentally knock over little ones! Because of that, HSBV will only rehome him to a family either without children or with children over the age of 10.

Story
Meet Effie, 1 year and 2 month old Mastiff mix who has a healthy appreciation for both naps and play time! She is a bit timid at first, but warms up very quickly. Effie is still young, so she is fairly quick to train and to learn new things. Effie is an amazing, kind dog - She is good with cats, dogs, and kids. After adopting Effie from the Humane Society, we discovered our senior cat was having an allergic reaction to her that worsened his pre-existing medical condition. For the sake of our cat’s health, we have made the difficult decision to find a new home for Effie. Effie thrives in a home with someone who can snuggle, play, and spend quality time with her.

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.

Story
This pups adoption fee has been partially sponsored by All Aboard or an All Aboard partner! The new adoption fee is reflected on the profile. IMPORTANT NOTE REGARDING THIS DOG: Ombre can be easily startled by new people and things. He is occasionally slower to meeting new people, especially men, and other dogs. Ombre has the potential to get overwhelmed easily and can resource guard. Ombre needs an adopter who is patient and willing to continue his training. Ombre is big guy with a lot of love to give! He came to us with a few quirks that his foster has been helping him work through and he is constantly making progress! He does need an experienced adopter who will be dedicated to continued positive reinforcement training and ongoing socialization. He has come a long way since his arrival in January 2023 and needs the perfect partner in crime to help him continue making progress! Ombre can be a bit skittish with new sounds or unexpected movements and can resource guard at times. He is occasionally slow to warm up to new men and other dogs, but not consistently! He can get overwhelmed in new high-activity environments, so continued socialization is a must. Ombre is very loving and curious, and acts like he is his foster's shadow. This loving boy is a classic case of a dog who is worth the effort! With the right, experienced adopter who is committed to setting him up for success through continued training and socialization, Ombre will absolutely blossom into his adopter's most dedicated friend! He is house and kennel trained.

Story
Meet Strawberry Lemonade!Affectionately called Berries or Bear by her foster family, this big St Bernard girl was found atop a mountain pass above Lukachukai AZ, starving, unable to walk and with five tiny newborn babies. She gave everything she had keep her babes alive and did an amazing job! After her rescue and during the course of rehabilitation, it became apparent that her inability to walk wasn’t just malnutrition and muscle atrophy. We did full body X-rays to make sure nothing was broken and found that she was not broken. Then Berries was seen at CSU neurology where an MRI was completed. There, she was diagnosed with Cerebellar Hypoplasia. This is a congenital disease where the cerebellum is malformed. The cerebellum is responsible for posture, balance, stability and fine motor skills. Bear is sometimes wobbly. She needs assistance on stairs and getting in and out of cars, however, she is a perfectly healthy dog otherwise. She is in no pain. There is no cure and there is no further treatment that can better her condition. The doctors have told us that she will likely live a completely normal life, with exception of some help climbing things, safety around water and things she could fall off of.Our Bear is the biggest sweetheart. She was an amazing mom to her babies and loved all of them fiercely. Her babes have all moved on to other fosters and are available for adoption as well! Berries is the best foster surrogate mom as well. She made two of our more recent foster puppies feel right at home. She loves little baby dogs. She acclimated quickly to our resident dogs and quickly claimed her place in the pack as if she’d been here forever. She loves to go for walks. She loves car rides. She loves adventures. Berries is fully potty trained and she sleeps on her dog bed all through the night. She walks amazing on leash. She is endearingly stubborn and sensitive and sweet. She is the best big girl ever. We think she is about 2 years old. We have loved every minute with her and are so happy to see her healthy and thriving.Bear has a disability but she is not at all unable. She is smart, strong and worthy of all the love in the world. She has survived unimaginable hunger, abandonment, abuse and uncertainty. She will make any adopter so lucky to share life with. If you’d like to meet our sweet girl, please apply at souldog.org.
