Story

Hi, All Mac, here short for Mac truck lol. If you love big goofy dogs, I'm your guy. I am 100 lbs. of cuddle bug. I really don't think I am as big as they say I am because I would prefer to just be a couch Potatoe and lay next to my people and chew on a bone. I am a people kind of guy and love everyone I meet. I can probably live with another dog, but he would have to be calmer like me. but little dogs and very young children I would be afraid of because I am clumsy and wouldn't want to hurt them. I definitely don't think I could handle cats. But I know a lot of commands they say I am really smart and a fast learner. I am potty trained but do not like cages. I am strong on a leash so I would need a strong owner. Fill out an app here. https://docs.google.com/forms/d/e/1FAIpQLSdsHBf5NUtvyBYpzWm6Z5Z0JosLBTsDC98oxPTfxtM9brrc7Q/viewform

Story

Meet Duke! A two year old Mastiff mix that is looking for his forever family. In the home he is house broken, crate trained, and loves to be with his humans. As an XL breed dog, he could still use some reinforcement of basic manners. He's very strong on leash and tends to jump and get a little mouthy when he plays or gets excited. A family with large breed experience that is willing to invest some time and energy into basic training would be ideal. Another requirement would be no children under 10. Outside the home, Duke is a tad insecure and can be slightly reactive to new dogs. After a quick introduction, however, he does great (especially with female dogs). He can, however, tend to get too excited and possessive over toys so a family that can maintain boundaries in their home would be required. As for cats... this big boy LOVES them and would have no problem sharing his space with a dog savvy feline.

Story

Charlie is a loving, snuggly boy that our family adopted 4 years ago. He believes he is a lapdog and if he tries to sit on your lap then you know he truly loves you. We had one dog when we adopted him, and they connected instantly and have been the best of friends ever since. In fact, he was a big part of helping our first pup overcome her separation anxiety. He is house-trained and does well off leash in a safe space with trusted owner. He is reactive towards other dogs, but in the sense that he gets super excited and wants to play, but it can be too much for other dogs. The reason we are looking to rehome him is because we had another child and she is now getting to a more mobile age, unfortunately triggering unpredictable behavior in Charlie. He has nipped the hand of both of our children and we feel he would be better in a home with no children and an experienced owner. It also takes him some time to warm up to new faces. This is sad for all of us, we want the best for him.
