Story
Rumble is a sweet 15 month old male English Mastiff. He has typical puppy behaviors such as mouthing and excitable greetings, but no observable human or dog directed aggression in the year we have had him. Unfortunately we are not able to give him the consistent attention and training he needs as we have a toddler at home and a baby on the way in one month. Rumble is playful and sweet and good with our toddler, but he is a big boy and needs an experienced handler.

Story
What my friends at OHS say about me:I am very cute but have proven myself to be quite the exuberant pup!I am easily overstimulated, which means I can get mouthy and worked up. I will need positive outlets for my energy and a calm environment.I may be shy at first, but once we get to know each other I may use you as an outlet for my excitement. Having treats or toys on hand is a good way to distract me.To prepare for your meet and greet, please take a moment to learn more about puppy ownership here!

Story
I adopted Miles in 2019 when he was two. He is kennel shy, he’s good with cats and kids. He has been known to growl at bigger dogs but nothing more. His previous owner was abusive and has made him sensitive to yelling. He loves to cuddle and will try to get on furniture but will figure out it’s not aloud if that’s not a thing you’d allow. He is harness trained, house trained. He’s just a big guy who wants to love. He is a mastiff and has started to slow down a bit due to age, no major issues with joints. All his items (leash, harness, collar, bed, toy, nail trimmers, food and container/ other items will go with him if wanted) other items will be donated to animal shelter.

Story
**This is a courtesy post for a dog not in our care**  Meet Honey! This energetic girl was pulled off of the euthanasia list in California and is now looking to find her forever home! Her temporary home says that she is doing great with crate training and is potty trained. At 71 lbs, Honey does require someone who is used to large, energetic dogs, as she is both of those things! She has shown excitement around other dogs but has not been officially dog tested yet. She has so far done great with humans, including at her vet visits. Interested in meeting Honey? Let us know and we can connect you! ##2826628##
