Story
10/06/26 15:13Gnocchi has been placed on FINAL as of 10/6/2026.*Gnocchi has been extended until 10/16/2026*He must be pulled by 5:00 PM on 10/16/2026, or he will be humanely euthanized.Gnocchi has demonstrated significant stress and arousal while housed in the shelter. When staff attempt to remove Gnocchi from his kennel, he bites at the leash during the leashing process and continues to do so afterward. There have been several instances where Gnocchi has bitten at the leash in close proximity to staff members’ hands. This behavior presents a safety concern for staff handling him and should be taken into consideration when determining appropriate handling procedures. While housed in his kennel, Gnocchi has been observed body slamming against the kennel door and pacing the length of the kennel. These behaviors are consistent with a high level of arousal or stress in the shelter environment and should be taken into consideration when developing an appropriate handling and management plan.Gnocchi was also introduced to another dog for a dog-to-dog (D2D) interaction. During play, Gnocchi was very forward and vocal but did not attempt to bite the helper dog. His ability to redirect his attention toward his handler and his lack of biting toward the other dog are important observations; however, his rapid approach and vocal behavior indicate that future dog-to-dog interactions should be carefully managed and closely supervised.Any future medical care, handling, leash work, and veterinary procedures should be carefully planned around Gnocchi`s stress and arousal level and conducted by experienced personnel. Given his documented leash biting, high arousal during kennel transitions, and repetitive kennel behaviors, placement should be with an experienced rescue organization that can provide a lower-stress environment, appropriate decompression time, individualized behavioral support, and appropriate safety and management protocols.Gnocchi is available for rescue or adoption with a waiver.A rescue partner must commit to and pull Gnocchi by 5:00 PM on 10/16/2026, or he will be humanely euthanized.EXTENSION REQUEST PROCESSA Rescue Group (RG) may request an extension of an animal`s Needs Rescue Final Date no later than 5:00 PM on the noted final date by emailing SJRescue@sanjoseca.gov, with a cc to a Division Manager or Shelter Operations Supervisor.10/05/26 07:02What I did today:I’m a great road trip buddy and sat politely in the back seat, watching the world go by, on our drive to the trail. Out on the trail I set a brisk pace and made sure my walker kept up – we passed people, bikes, and cars without a second glance, and I capped off the walk with a very satisfying cool-down splash in the creek. I finished the outing the right way: soaking up all the pets and butt scratches I could get, because a big guy like me deserves big love.What to know about this dog· A strong boy who likes a fast pace and can pull – would be best with a strong handler who can keep up with him· Good at passing people, bikes, and cars – gets excited when he sees other dogs and will pull toward them· Treat-motivated and knows “sit”· Affectionate and loves pets and butt scratches· Would thrive in an active home with a strong handler who can match his energy and give him the adventure-filled life he deservesThree words to describe me: Affectionate, Playful, Cheerful08/19/26 15:27Gnocchi has been placed on needs rescue URGENT for his consistent high FAS (fear, anxiety, stress) score since begin here at the shelter.Gnocchi is a handsome 7 year old mastiff that has been in the shelter since June. When he first got here, his behavior was very inconsistent. Some days he would be loose and happy to greet people at the front of his kennel and other times he was barring teeth. Now that Gnocchi has had time to decompress, he is not showing any signs of aggression towards people or other dogs. In the kennel now, he is constantly barking and jumping. Gnocchi knows that the kennel life is not for him and he tells us that every time he returns from his walks. He is always super happy to leave the kennel for his daily walk, but he is known to stall when it is time to return. And who can blame him. He wants a life outside of the kennel with someone who will give him all the love he deserves. Will you be the one to help this sweet boy and give him a home away from the shelter?

Story
Romeo is very sweet 6 year old boy but the vets think he may be younger. He would love to be a family dog and definitely wants to find his forever home, but can be protective of his people and his space. That being said once he knows you are part of the family he listens very well and knows many commands, sit, stay, down, shake, wait. He is slow to warm up to new people but once he has been introduced to you he is a gentle giant and big couch potato that loves to cuddle. He also really enjoys going for a ride in the car. It is not recommended to have young kids due to his size. He is good on the leash and knows many commands but needs someone that is not afraid of his size and can properly handle him. Experienced adopter with larger breeds is a must. No other dogs or animals in the household and not a good candidate for crates.

Story
Monte is a delightful, energetic, and loving neutered pit bull mix, weighing about 89 pounds. At around 3 years old, he’s full of life and ready to find his forever home. After undergoing TPLO surgery on his right hind leg, Monte has been cleared for adoption and is feeling back to 100%. Although he has a partially torn cruciate on his left hind leg, his vet advises against surgery unless he shows signs of pain. Monte enjoys running zoomies in the yard and relaxing with a good chew bone. He gets along well with other dogs his size but plays rough, so future housemates should be at least 40 pounds. He knows basic commands like sit, stay, lay down, go to your crate, and waits for his food until released. His favorite treat is French fries! Monte is crate-trained and will let out a yip when he needs to go outside. He’s excited on a leash but calms down after a while, though he still pulls. His foster parents taught him not to jump and his new family will need to continue to reinforce the behavior, so a home without children under 10 is recommended. While Monte has been fine with cats from a distance, he seems too interested, and my cats are scared of him. Therefore, a cat-free home is best. Monte loves cuddles and thinks he’s a small lap dog, despite his size. Monte is fantastic with new people outside the house and is always a hit at the vet. At home, he’s cautious initially but relaxes once introduced by me or my husband. I believe he’ll do the same with his new owners and home. Monte is eager to find a loving family to share his life with! If you are interested in Monte, please complete our application on 1luckydogrescue.org or email olveiry@yahoo.com along with some information about the yourself.
