Osiris is a Mastiff mix puppy that is new to our program. So far he has been very social with humans and other dogs, aiming to please! Potential adopters need to know that he is a BIG puppy with puppy behaviors. Adopters need to be willing to spend the time with him to teach him how to be the best boy! Osiris will be a very large full-grown dog and will need the space to run and play! As we learn more about him we will update! If you are a lover of large breeds don’t hesitate to apply for this sweet boy!
