You can fill out an adoption application online on our official website. Hi! My name is Juliana! I'm about 4 years old, 78 lbs. and housetrained. I am timid though, so I  need a special home, one with another dog (or dogs), a fenced in yard and really patient people. I'm so lucky to have a great foster home but I know my  FUR ever family is out there somewhere. Julianna is spayed, microchipped, and vaccinated. Go to our website to see more pictures of her.

Story
Arlo is good with people, and he is 6 years old. He can be aggressive with other animals though. Recently he had an incident with a cat he has lived with all of his life. I work 7am to 7pm on most days, and unfortunately he is the product of a divorce. Arlo needs more room to run, more attention, and it seems that he would be better in a single animal home, however he might just need a change. He is very loving (lots of kisses/licks). This is heart breaking but unfortunately it is unsustainable and not fair to him. I would love to find him a great home where he can be the awesome dog that I truly know he is.

Here are fun facts his owner wants you to know: - Twix / 3yo / Male/ Neutered / 65 lbs / In great health - Mastiff/Herding mix - Up to date on vax since 8/25/25 - Will do best with experienced, active dog owners who would be able to be consistent with good daily habits to strengthen his foundational training.

He is passionate about learning. - Housetrained and very communicative about needing the bathroom. Will whine/grumble, give paw or look at door. - He is crate trained and loves his crate. He will crate himself to take naps throughout the day and also will tuck himself to bed when the sun goes down and sleeps through the night. - Not destructive in the home at all, even when left alone. No separation anxiety. - Walks nice on leash! Big sniffer. Knows heel. - Energy level is average/medium. Will match your energy to be very active or a couch potato. Greets with excitement for just a few minutes. - Shines with his family/pack and loves physical and verbal affection. - Total silly playful goofball and sweetie pie who just wants to love. - Loves long walks (hiking and camping), swimming, tug and fetch. - Nervous when not introduced to new dogs and new people but eased with structured introduction or pack walk. 100% success rate when introduced to new people.

All of our dogs are rescued from local shelters and the general public.
