Story
Meet Louie (ACCT-A-264831)! 💙 This sweet, sensitive boy is looking for a patient person who will give him the time and kindness he needs to feel safe. Louie is very food-motivated, knows how to sit and offer his paw, and has shown that once he starts to feel comfortable, he’ll come over for affection, lean against you, and even rest his head in your lap. He can be nervous about being leashed and handled, so a gentle approach, tasty treats, and letting him move at his own pace are key to helping him shine. He’s also made a lovely start with other dogs, greeting and mingling with them in playgroup. Could you be the understanding friend who helps Louie discover how good life can be? 📽️Videos📽️: Louie knows sit and paw: https://youtube.com/shorts/MdoRXMxd99s?is=2S_vL8d54twE4-W3 Playgroup 10/26 https://youtu.be/2gcYjF0FnDY Playgroup 10/26 https://youtu.be/2zyIU_cxzw4 Sit and Paw https://youtube.com/shorts/ooMJ2wq493E?si=pkQP7Kuo14PiWBOl Meeting a Friend https://youtube.com/shorts/gNAdIxbpCao?si=bQaQkdZRnkYzV99e ⭐Behavioral Notes⭐ 11/1 Per Volunteer : "I wanted to get Louie outside, since he hasn't been out in several days. I had to offer him lots of treats ( he liked the bacon strips) then lower the divider and lasso him. He steps out slowly. He is spooked by the loud noises in the kennels. As we walked past the dogs and they bark at him he shrinks back, and the outside noises make him uncomfortable, also. He walks great on the leash; it's really a loose leash walk, he stays right beside me. He flinches with any sudden movement towards him, I went to move my leash stopper and he flinched. He has a cold, so we headed to the cold club yard. There he wanders sometimes smelling, but then, he'll just stop and sit or stand like he's observing. He didn't approach me for pets, nor play with any toys I tossed. He showed me he will sit beautifully for a treat and offer me his paw. He's very skinny, so treats are important to him. Another loose leash walk back into the shelter, but he was very skittish when I had to clip the leash. However, he went directly into his kennel." Per staff 10/31: Leashing Louie up to take for vet checks. Presented in kennel on cot, loose body ears to side tail nub wags. Spoke with baby voice and gave pieces of hot dog thru kennel door to introduce myself. Opened kennel door and presented leash and Louie’s body tensed and gave whale eyes. He did not like my hands over his head at all. Kept feeding pieces of hotdog through the loop but was unsuccessful in placing loop over head as Louie kept backing away from the leash, whale eyes and tail nub tucked. Placed loop onto floor, and put a hot dog in the middle. Was then able to pick up loop while he ate the hotdog piece and loop was successfully over his head and he did not panic. While at vet checks tolerated all handling very sweet boy. 10/26/2026: Playgroup 10/26: Entered the yard with low tail, ears back, wide eyes. Sniffed around then loosened up and mingled with the other dogs, good greets. 10/26/2026: Brought out for playgroup, came to the front of kennel with soft eyes and ears back. When i opened the door retreated back, came forward for treats and able to gently drop leash from above to leash him. Came right out and walked loose leash to the yard. When I sat down in the yard came over to me and leaned against me allowing all handling with a low tail and ears back. When attempting to put a collar on him he whale eyed and moved away. Called for a second person, with treats and moving slowly able to get a collar on. For transferring back to a slip lead after playgroup with treats and moving slowly able to get back on and walked back to kennel loose leash. 10/26/2026: Louie was being a bit silly tonight and hanging out on his back on his bed with his legs in the air! I happened to catch him in the act, and when he saw me he jumped up and came to the kennel door with soft eyes and ears back. 10/25/2026: Louis continues to be fearful being leashed, I assisted with leashing and handed Louis off to a volunteer once out of kennel. When I approached with the leash, his brow was furrowed with ears to the side. He retreated to the back of the kennel and was ignoring the cheese I was tossing in. I showed him the leash and opened the door a little bit and he came towards the door tried to dodge the leash two times and then ultimately put his head in the leash and exited the kennel. When I handed him off, Louis’s body language remain hunched with ears back, appearing timid and worried. 10/19/2026: Kennel Presentation: Came to the front of his kennel with wide eyes, ears back, tail low, took a treat through the bars. Leash Skills: Backed up when I presented the leash and moved to the back side. Came to the front when I removed the leash and I closed the divider. Would back up with a front paw raised when the leash was near him. Able to leash with treats on the ground and lassoing. Once leashed came out and walked slowly, tail tucked, ears back. Sociability: Walked slowly around the yard, head low, tail low, ears back. Attempted handling at first and gave side eye, skin crawled and moved away quickly. Spent some time and offered treats which he took. Sat on the bench and he leaned onto me gently, allowed all handling with tail low, ears back, rested his head on my lap. Play: No interest in toys. Dog Interaction: n/a Return to Kennel: When picking up his leash to return, gave a closed mouth head whip, ears pinned back, tail tucked and moved away quickly. Walked back slowly with the same body language. Did a treat scatter to clip my leash and he hopped right into kennel. Leash was removed with clip. Color Level: Exp blue 10/16/2026: In kennel presenting with whale eye, tense body lip, licks, avoiding eye contact. Eating treats came to the front, and showing him the leash. He retreated to his bed. Put down the guillotine door use treats on the ground to get his head down to be able to lasso. Once leashed walked out slowly with tail pasted down. Peed and pooped immediately once outside. My initial attempt to touch him was while he was sniffing a tree and his skin crawled. He tucked his butt and flinched. we sat on a bench offered him treats came over, leaned into my leg while I pet his back gently. Also did sit and paw for another handler. Met a handler - tail raised to middle looser body language, curious and sniffing her, appeared to loosen up a lot more around her. 10/14/2026: TTA- whale eyeing, jumps when touched, tense body, and lip licking. Did a mostly visual exam, very food motivated. Would come back up to the handler with the high value and look for attention when in the exam room. Starting Traz 10/14/2026: Took a while to get dog on leash, ate food from my hands, very skiddish when attempting to leash. ACCT Philly is located at 111 West Hunting Park Ave in Philadelphia.

You can fill out an adoption application online on our official website. Fill out an Adoption Application Please take the time to research the breed before considering fostering/adoption. Because of their immense size, strength, and strong guardian instincts, they are generally not recommended for first-time or novice owners. They require experienced handling, early socialization, and ongoing training throughout their lives. Meet Cosmo...an Independent Spirit, Born Guardian Personality: Cosmo is a spirited, adventurous, intelligent Caucasian Shepherd puppy with a big personality and natural guardian instincts. She absolutely loves having an older sister and brother! She has already learned so much from watching them, including manners and how to look after and protect the herd. She is observant, confident, curious, and always ready for her next adventure. This is a working guardian breed, and her protective instincts are already beginning to develop. She needs a family who understands that these traits are part of who she is and is prepared to guide them through consistent training, structure, and responsible socialization. Cosmo is also very independent and already shows the self-assured nature of her breed. She likes to explore, observe, and figure things out for herself. She isn't just looking for someone to entertain her—she has a mind of her own and natural instincts that will need to be guided by someone who understands guardian breeds. Her independence is part of what makes her special, but it also means she'll need a patient, confident owner who can provide consistent boundaries without expecting a people-pleasing dog. Favorite Activities: Running, exploring, playing, and going on wild adventures ALL DAY LONG! Cosmo loves having room to roam, following the animals, observing her surroundings, and learning from the older dogs. She enjoys being involved in everything happening around the homestead and is happiest when she has space to explore and a job to do. She is an energetic puppy who needs plenty of room, stimulation, and appropriate outlets for her natural instincts. A small yard or city lifestyle would not be a good fit for her. Medical Issues: No known medical issues reported at this time. What would be the best kind of home: Cosmo needs an experienced, committed home that understands and respects the Caucasian Shepherd breed. A rural property, farm, or homestead with substantial, secure fencing and plenty of room to roam would be ideal. She is accustomed to being around animals and developing her natural livestock guardian instincts, so a home that understands working guardian dogs would be best. She would benefit from having confident, well-mannered canine companions who can help show her the ropes, although any resident dogs must be a good match for her as she matures. Her new family must be prepared to provide consistent boundaries, structured training, early and ongoing socialization, and responsible management of her developing protective instincts. Food is a serious business for Cosmo! She has already shown resource-guarding tendencies, so her adopters must understand resource guarding and be willing to manage it safely and work on it through appropriate, positive training. She needs careful management around food and other valuable resources, not punishment or confrontational attempts to take things away. Cosmo is adorable, playful, and full of adventure, but she is also growing into a powerful guardian breed with strong instincts. She is not a fit for an apartment, a small city yard, or a home unfamiliar with large livestock guardian breeds. She needs space, knowledgeable handling, and a family willing to help her grow into a confident, stable, well-managed adult dog.Click here to watch a video of Cosmo.Visit this organization's web site to see any additional information available about this pet.
