Story

Hi all! I’m Brody! I’m 4 years old and have been told I’m a total meat head who isn’t always aware just how big he is. I hear everyone calling me a handsome beefcake, which I can only imagine is a good thing. ☺️So far, everyone thinks I’m a mastiff/pit bull mix, hence the beefcake comments, but we’re not 100% sure as we haven’t done a DNA test. Regardless of my breed, I know I’m 100% handsome, because my foster mama tells me every day! 😍 I’ve got a big ole head, and a giant heart to match. 🫶 Not only am I easy on the eyes, but I’m also fully trained! I’ve got my basic obedience down, walk great on a leash and am crate trained. I love ALL dogs, even the littles, and my motto is #BALLISLIFE! I could play ball EVERY DAY and would love a home with a family who will play with me! But not to worry! I’m also perfectly content with some R&R at home and can be a lazy potato. My ideal home would be with a family who is patient and kind. I’ve had a lot happen to me in my 4 years on this earth, so I can be nervous meeting new people. However, I can also warm up really fast, and once you’re in, you’re in forever and we’ll be the bestest friends forever! 👯🤗 I’d also do best in a home with strong leaders, because let’s face it… I don’t like having to make choices. I mean, can ya blame me? Making decisions is a tiring thing, and why spend time doing that when I could be having fun! I’m fully vetted, neutered, current on all vaccines, microchipped and looking for my forever family.

Story

Pitbull/Mastiff 5 year old male dog needs a good home. He is not neutered, vaccines unknown, previous owner was moving and couldn’t take him so we stepped in to foster until a home could be found. We have 3 dogs and live in an apartment, otherwise we would keep him. He is good around other dogs, friendly with people & kids and generally a big goofball. He is not crate trained, but is house trained. Please consider adopting him. No breeders, we are looking for a good home for him. Someone that will train him (he is very smart & trainable) and has a backyard that he can run around in.

Ontario, CA

(when grown) Large 61-100 lbs (28-45 kg)

Details

House-trained, Spayed or Neutered, Shots are up-to-date,

Story

Koda is a very sweet and playful Mastiff looking for her forever home. She does well on a leash and listens well even if she's not sure of the command. She did come from a home where she was an outdoor-only dog, so she will need some extra training to be housebroken. She's never been with other dogs before but she pays no mind to her neighbors in her kennel. Koda is an absolute no for cats please. She is good with kids and very gentle. ##2178866##
