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
Say hello to Blue – a super friendly 1-year-old pup who’s full of love and ready to find his forever home! Blue is great with other dogs, enjoys playtime, and is always happy to be around people. He appears to be potty trained and has been very sweet with our staff. While he’s a social butterfly with pups and people, cats aren’t his thing, so he’ll do best in a cat-free home. If you’re looking for a fun, loyal companion, Blue might just be your perfect match! 💙
