Story
This is breezy! I love this dog so much he’s so amazing and full of energy, unfortunately cannot keep him any longer because of housing issue and working to much. I just want to find someone that will be able to give him the time and attention he deserves. He is a great dog with a lot of goofball energy. I would prefer to find someone that is willing to foster him for an extended period of time until I am able to get him back. Unless that person/ family truly loves him to the point where they cannot get rid of him. Then sticking with that family would be easy decision for me to make because it’s very hard for me to even make this one I just want him to have a great life. And it breaks my heart to have to find him a new home. I’d very much prefer also if the person who chooses to foster/ adopt him is okay with keeping in contact and okay with visiting occasionally that would be greatly appreciated as this is not an easy thing for me to deal with. I will pay for all his food

Story
Mr.Rogers lives up to his name. He has the sweetest soul of any dog I have ever met. He doesnt bark at all. He's a cuddle bug and he will always be right next to you. He is more of a couch potato than he is a runner. He does enjoy a good bone to chew on. He is up to date on all his shots. microchipped as well. He looks bigger than he is. Hes got more black mouth curr in him than mastiff, you wouldnt think he was mastiff if you saw him in person. He needs a home where he can enjoy just being a lazy boy with family. nice yard for him to get a little exercise as well. He doesnt need much. Like I said hes just a lazy ol boy. Hes about 4-5 years old. He does good with dogs. But I would always recommend introducing dogs to dogs in slow amounts first. Thats a given. Unknown with cats. He does chase lizards. He is completely crate trained and poty drained. Ive had 0 accidents. Let mister rogers be your family dog. He needs a good home.

Story
The legendary, the iconic , Meryl Streep is on her way back to boarding and sadly in need of a new foster home Her current foster raves and raves about Meryl and what a good, easy girl she is but life happens and has to take a break from fostering for a while. Meryl is dog and kid friendly, but no cats please! She has a special love for small dogs which is just the most adorable thing to witness. She is crate and house trained, so much so that she puts herself to bed in her crate every night She is great in the car and game for any adventure, she goes to weekly trivia with foster mom and has become a fav local patron! When we say that Meryl is so easy, we really and truly mean it. She gets the zooms with her doggy friends but is otherwise content to do her best potato reenactment on the couch or lounge in her bed. She is 6-7 years old and weighs in at 65-70 pounds, but she’s a gentle giant with that much more love to give. If you are interested in fostering we can promise that she’d be the perfect first timer dog, or if you think Meryl might be your forever kind of dog, don’t hesitate to reach out! I mean, how many times are you going to be able to say that Meryl Streep is at your house!?! June 13, 2026, 12:23 am
