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
10/06/26 15:13Gnocchi has been placed on FINAL as of 10/6/2026.He must be pulled by 5:00 PM on 10/13/2026, 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 10/13/2026, 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
Lila is a beautiful Mastiff mix living her best life as our resident gentle giant and professional couch potato while she waits for her forever home 💛 This sweet girl is equal parts lover, snuggler, and car-ride breeze enthusiast. If you have a couch and a car window that rolls down halfway… congratulations, you already have two of Lila’s favorite things. With new people, Lila is a polite little introvert in a big dog body. She may play it cool at first, but once you pass her vibe check, she’ll wander over for a hand sniff and some gentle pets. Lila is still very much a baby brain inside a giant body, so she’s working on crate training, impulse control, and remembering that manners matter. She truly wants to be good… sometimes her dramatic side just makes a guest appearance. Structure, consistency, and a confident human are helping her improve every day. Lila is a mastiff mix, which means she’s a big girl with an even bigger heart. She can be a little unsure of herself at times, but with confident leadership and reassurance she settles in beautifully and bonds deeply with her people. Because of her size, puppy energy, and chase instincts, Lila is looking for a home without small children or small animals. 📍 Fostered in San Jose, CA Apply to adopt Lila: www.cabullyrescue.org/adopt

MEET KATE! A LITTLE SHY, A LOT SILLY, AND 100% WORTH GETTING TO KNOW! 💕 Kate is the kind of girl who may take a minute to warm up… but once she decides you’re safe, congratulations—you’ve officially been chosen. 🥹 ❤️ And Kate does NOT take her job as your loyal sidekick lightly! This beautiful girl is still growing into her body and outgrowing her puppy stage, which means she’s got a little bit of awkward teenager energy going on. 😂 She may initially be reserved in new situations, but give her a little time and her silly, happy personality comes bursting out. Once she trusts you, she is incredibly affectionate, devoted, and will happily follow her favorite human from room to room like a furry little security detail. 👀 🚗 Road trip queen: Kate travels like a DREAM. Most of the time you’ll find her curled up in a little ball, snoozing away while you run errands. Basically, she’s the perfect passenger and has already mastered the art of “Are we there yet?” by simply sleeping through the entire trip. 😂 🐶 Dog social butterfly: Kate has been great with small dogs, big dogs, and groups of dogs! She has excellent doggy social skills and quickly figures out who wants to PLAY. She loves a good game of chase, being chased, and the occasional friendly boxing match. 🥊😂 She can play a little rough, though, so her ideal doggy friends will appreciate her enthusiastic wrestling style. And when playtime is over? She LOVES snuggling up next to another dog for a cozy nap. 🥰 👨 Men: Kate can be a little unsure around men at first, but she has made wonderful progress in her foster home and has learned that the boys aren't so scary after all. She just needs someone willing to let her build that confidence at her own pace. 🐦 Cats & critters: Kate hasn't shown any prey drive and doesn't bother the foster home's pet birds, but she hasn't been tested living with cats yet. 🏡 Home life: Kate sleeps peacefully in her crate all night and even puts herself to bed! She knows when it's bedtime and happily heads into her crate on her own⭐️ Appy to adopt Kate! www.cabullyrescue.org/adopt Fostered in Los Gatos 1-2 years old 65-70lbs
