Story
Let’s welcome Sammy into our Bean’s Beagles family. He is so happy to be safe and cannot wait to sit down and tell us all about him. Sammy is a 3-year-old, 42 pound tricolor male Harrier mix who was rescued from OC Animal Care around May 13th and he was at risk due to his history. He was reportedly passed around to several unhoused owners over a period of time, and has a bite history. However, based on the history, it seems possible Sammy was in not ideal conditions and questionable treatment, so he may have responded out of fear or to how he was being treated in those conditions. He has not shown aggression or biting behavior/resource guarding since he has been in our care. Regardless, since he was been in our care, we have housed him in a secure boarding kennel while we working with our trainer and Sammy. His initial assessment was positive, he appears to have potential, but definitely appears fearful to men and trucks going by, which we’re working on. However, Sammy has been cooperative with kennel staff with feedings, potty breaks, and being leashed, with no further bite incidents reported, though we’re all taking the proper precautions. He has been training with Yolanda, including socialization outings, and has definitely improved over time and seems happy. We are hopeful that with the right owner, patience, and training, Sammy can learn that the world can be a safe place, there are nice, patient people out there, and that he deserves a wonderful home. Sammy will need a very patient, caring, and special person who is willing to work on training, and his home should have no other dogs, children, or cats as he will need to be a priority as well as safety for all. Sammy will need a local foster who will be willing to work with our trainer as he goes back into a home environment. Welcome Sammy!

Story
Meet Rye Bagel! Rye Bagel was rescued from San Diego after his owner passed away and the family could not keep him sadly, so he was surrendered. He apparently lived primarily in an outdoor kennel with about 13 dogs. Luckily, the generous Foundation for Care of Indigent Animals in Spring Valley looked after him, got him updated on his vaccinations, neutered, a dental cleaning, and examination with the veterinarian. He had a growth removed from his leg, but the vet was not concerned about the growth. Then, he was transported to Orange County on January 17, 2026 and became a Bean’s Beagle. We were initially told he was 16 years old, but the vet said he actually appears to be closer to 10-12 years old. So far, he has been enjoying walks in the neighborhood at his leisurely pace, he is friendly with people and other dogs on walks, enjoys looking out the window from his favorite spot, takes his naps, and is a “delight” to have in the home. He has been kind and gentle with the kids in the foster home, and enjoys cuddling. Bagel patiently watches his foster prepare meals, but has not tried to take the food, good manners! Bagel does not appear crate-trained yet, though he prefers to sleep on a blanket or bed just on the floor outside of the crate or with the crate door open. This may be due to him spending much of his life in a kennel previously. He appears to know to go potty on walks or outside, with no accidents typically and does well overnight with house-training, which is great! Bagel is looking for his forever home in the Southern California area. He may do best in a home where he is the only dog, or someone willing to slowly introduce him to other dogs. He has done well in his foster home with neighborhood dogs, at adoption events, and in the home, but these interactions should be monitored to ensure they’re a good match.

Story
Meet Mable! Mable’s freedom ride!! She is a 2 year old spayed female who will be looking for a forever and ever home soon in SOUTHERN CALIFORNIA only. No out of state applicants. Let’s let her decompress, relax and please let us get to know her a little more. All we know right now is she needs a home with no babies, toddlers or young children. She has a history of resource guarding and needs behavioral evaluation, training, and a committed adopter. Mable was trained for scent detection and knows a little obedience, but will need a human to give her structure, boundaries and training or she might think she is pack leader and take over. Not quite the job she should have. No cats. Alumni Finn will be testing her soon to see how she does with other dogs. We will update you on her progress. Welcome Mable to the Bean’s Beagles Family ❤

Story
Meet Randy! Randy is about 10 months old now, we originally rescued him in April 2026. We rescued him from another partner rescue in El Centro, California and he apparently was either found as a stray in Mexicali or born in the shelter with siblings. We don’t know much about his past, but he is a sweet puppy. We were told he was a beagle-basset hound mix, though we recently DNA tested him (see below). Regardless, he is a sweet boy who is looking for a foster home or foster-to-adopt home we are trying very hard to help him find one ASAP! So far in his foster home, we’ve learned that Randy is a very sweet boy, loves attention, playing with the other dogs in the house, likes to sunbathe, and sleeps well in his crate overnight, though he’d love to sleep in bed if he had the chance. He loves to be near people, snuggles, rides well in the car, responds well to his foster, and enjoys going on walks through the neighborhood. Guess what? He hasn’t had one accident in his foster home so far! That’s awesome for such a young puppy just learning the ropes. He is walking well on the leash, but has shown some slight fears in new places or to new people, but over time and exposure/socialization he does well. Can you blame him? He is still a puppy and has been through so much already, everything is new to him. Once he has consistency in his home situation and trust of an owner, we’re sure he’ll settle in even more. Let’s not let Randy wait long to find his forever home, he is such a sweet puppy and he deserves the best! Even if he is not a beagle, he’s a very good dog, has a lot of potential to live with other dogs or on his own, but is looking for a calm environment where he can learn, grow, and find his people. Contact us if you have questions or apply here on our website to adopt Randy! *Note: as of 10/7/26 we have Randy's DNA and he is 22% American Pit Bull Terrier, 21% American Staffordshire Terrier, 6% Boxer, 2% Neapolitan Mastiff, 26% American Cocker Spaniel, 9% Labrador Retriever, 4% German Shepherd, 3% Australian Cattle Dog, 3% Chihuahua, 2% Chow Chow, 1% Chinese Shar-Pei, and 1% Polynesian Street Dog estimated by EmbarkDNA. So, he is not a beagle or hound mix as we were originally told, but he will be a "beagle in spirit". Regardless, he's a purebred good boy needing a foster or forever home!

Story
Dash is a 6-year-old neutered male beagle who will need someone who will not only be committed to him for life, but committed to following his trainer's suggestions and strong advice. His trainers are Zack and Gabi from Falco Dog Training in Yorba Linda. Dash needs to have someone who gives him consistent structure, guidance, and strong boundaries. He comes with a history of resource guarding and bite history unfortunately, therefore any potential adopter must be fully committed to following the trainers’ guidelines exactly, and be mindful to not to give too much freedom or affection to Dash too soon, as he may try to take over and needs time to transition into a new home and routine. Any potential adopter must also commit to either individual or group sessions with our trainer from day one and to follow the trainers’ guidelines in order to be successful. Dash was surrendered by his previous owner a few months ago due to change in lifestyle. He had limited socialization with other dogs, though he is friendly with most people and dogs it seems. He is all up to date on vaccinations, had a dental cleaning and treatment of allergies upon intake to the rescue, and he is otherwise healthy. He weighed 26 pounds upon intake. He is house-trained and crate-trained, but may need reinforcement of this training in a new home and routine. In his foster placement, Dash enjoyed his walks, playing with toys, and was a sweet friendly boy. He enjoyed being taken outside often, and seems to enjoy potty breaks every 3-4 hours. Generally, Dash is a sweet, easy-going, friendly, curious, and happy boy who is excited to go for walks, and may need to work on leash manners. He has previously lived with children, but it is recommended that he go to an adult-only home with no other dogs or cats. He know some basic commands such as sit, stay, leave it, and come, and has been evaluated by our trainer. He is very food motivated like most beagles. Dash is a very happy-go-lucky loving boy who will give you his heart in return for a forever home, and we want his next adventure to be a successful one. If you have the time, patience, and you are seriously willing to follow the trainers’ rules and guidelines for resource guarding and training needs, please consider submitting an application for Dash, you won't be sorry once he knows you are his leader. Note: Potential Adopters must be: 1. Located in Southern California to be near our trainer. 2. Willing to invest and commit to training sessions with Falco Dog Training from the start with Dash. 3. No children, other dogs, or cats in the home. 4. Understand resource guarding and willing to work on this with Dash in the long term. For questions or concerns, please contact us at info@beans-beagles.org and apply on our website to be considered: https://beans-beagles.org/available-dogs/dash/
