Story
Frankie is a true cuddle bug who thrives on being close to his people and soaking up all the affection he can get. He is naturally curious and prefers exploring his surroundings and taking in the world around him over playing with toys. Every corner, sound, and movement is interesting to him, and he likes to observe everything happening nearby. Frankie has a sweet habit of leaning in for hugs. He also loves to give gentle kisses as his way of showing just how much he enjoys being with you.

Story
Toffee is an energetic pup with a nose that never quits and a curiosity for the world around her. Walks with Toffee are always an adventure because she loves stopping to sniff every little thing along the way. While toys don’t really capture her attention, spotting birds is one of her favorite pastimes and she could spend ages watching them flutter about. Her playful spirit and inquisitive personality make every day feel exciting and full of discovery. Toffee would love a family that enjoys exploring the outdoors as much as she does.

Biggie

Bullmastiff

Male, 2 yrs 7 mos
Riverside, CA
Size
(when grown) X-Large 101 lbs (46 kg) or more
Details
Good with cats, House-trained, Spayed or Neutered,
Story
Biggie is a large handsome bullmastiff. He was found tied to a stop sign on Thanksgiving at 4:00 AM. He was skinny and it was obvious he had never been inside a home before. He has finished his vetting meaning he is fully vaccinated, microchipped, and neutered now. He is a goofy boy and loves to walk around with a food bowl in his mouth like a pacifier. He thins he is a 10 pound lap dog but he's really a 90 pound lap dog! He is a very sweet boy, listens well, and just wants to be laying by his human companion all the time. He is crate trained, and has learned to co habitat with kitties. Although we do not recommend a home with other dogs as he is dog selective and doesn't get along too well with dominant dogs and really doesn't like or have the patience for little dogs and puppies. He is a very chill couch potatoe who wears his heart on his paw and is a sensitive guy. If interested in meeting Biggie, please complete the adoption application and once reviewed and approved someone will reach out to schedule the one on one meet and greet.

Bullmastiff

Female, Young
Riverside, CA
Size
(when grown) Large 61-100 lbs (28-45 kg)

Good with kids, Not good with dogs, Not good with cats, House-trained,
Story
Lilo is a two and a half female purebred bullmastiff. She is AKC registered and a really sweet girl who loves to be with people. She is fairly good a leash but would much rather be napping. :) She is fully kennel and house trained. She is not getting along with our frenchie so we are needing to look at options for either one to be adopted for safety. If you think Lilo would be a good fit for your family please reach out. Thanks!
