Story

Montana is an affectionate 4-year-old Lab/Pit mix who’s ready to be your loyal companion for life. This sweet girl is a fetch fanatic who lives for playtime and loves nothing more than chasing balls with her favorite humans. She’s both treat and toy motivated and ready to learn new tricks. Montana gets along fine with other dogs, but she’s truly a people-focused pup who wants to be your number-one play partner. On a recent Doggie Day Out adventure, she proved to be a calm car passenger and a wonderful trail companion. She enjoys sniffy walks and likes to lead the way without pulling on the leash. Though Montana can be a little shy when meeting new people, she warms up quickly with patience (and a few tasty treats). Once she feels comfortable, she enjoys gentle petting and cuddle time with her friends. If you can toss a tennis ball, you’re already in her inner circle! Montana was placed on final because shelter life has become overwhelming for her. Repeated encounters with unfamiliar people reaching into her kennel have left her feeling uneasy, and she may growl or show her teeth to ask for space. But outside the kennel, Montana’s true personality shines—sweet, playful, and full of love. Montana will thrive in a calm, patient home that gives her time to decompress and build trus ##2599337##

Story

STABBED BY HIS OWNER, NOW HES ALL ALONE Rescue preferred This is not the life Buster deserves to be living Buster came to the shelter in July after being stabbed by his owner with a sword. He was seen by an offsite vet, his owner was arrested, and he has been here as evidence ever since. His owner’s case was dismissed due to a lack of evidence (unfortunately), and Buster is now FINALLY able to leave the shelter after being cooped up in a kennel for over FIVE MONTHS. We prefer that Buster goes to a rescue, as we do not want Buster to ever have to go back to the person who did this to him— he deserves better. He deserves love. Buster’s story is sad, but please do not bring him into your home unprepared just because his story tugs at your heart. Anyone who takes Buster home needs to be prepared for a long and potentially rocky and frustrating decompression process. Being in a shelter for so long is not easy and takes a toll on a dog’s psyche (and behaviors). He needs space and grace to heal. Currently, Buster’s mind is all over the place so it takes him a bit to connect with people because he is just too overwhelmed. He needs someone who understands that it may not be love at first sight. Someone patient who will not necessarily shower him with love but will give him structure, boundaries, and a safe place to rest his bones. Buster seems to want to be with dogs, but again, he needs to decompress. He lacks manners and shows some dominant behaviors, possibly due to how stressed he is. We cannot say for sure how his opinion of dogs and behaviors toward them will change once he is in a home, but currently he would do best with SLOW intros (decompression!!!!) and a tolerant, friendly dog. ##2619651##

Story

Dillon was 1.5yrs young when we adopted him from Milpitas Humane Society in 2019. He had an ear infection being treated at the time. Recently it came back. Besides that he is happy and healthy. We live with 3 children (2 teens and a toddler) and Dillon is very gently with them and is always excited to see them coming home from school. Unfortunately we are relocating and downsizing and overall don’t have time and can not afford taking him to the vet for his ear infection due to one of our children going under heart surgery which is putting us in a difficult time financially. New home we are planning to move in does not allow “large” dogs. I am very heartbroken writing this post but I am hoping to find my Dillon a good home that has the time for him.

Story

2 yr old tricolor M/N Kelpie/GSD mix Looking for a dogs dog?? Gunner is your guy! He was comfortable enough around me, allowed touch, took treats, interacted some with me, but he really really wanted to play with the big dog in the next yard. He wasn't aloof though! Took treats gently, eager to please and loved being called a good boi, it was a fun yard time for both us us He does seem to be feeling the stress from the shelter, some have had some trouble getting him out of his kennel but he was perfectly behaved for me. This is an active breed, he will need consistent physical and mental exercise to be happy, it is likely what is causing his current stress and occasional barrier reactivity. It is worth noting that he was a very loud bork monster when I first approached his kennel but after 3 treats he was ready to follow me anywhere I was going Knows how to sit, walks well on the leash (just a tiny bit of pulling) and seemed potty trained!! ##2528145##
