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.

(when grown) Large 61-100 lbs (28-45 kg)

Details

Good with kids, Not good with dogs, Not good with cats, Needs experienced adopter, House-trained, Spayed or Neutered, Shots are up-to-date,

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.

For more information, visit us at www.sheltersurvivors.com THIS IS A COURTESY POSTING – Twix is not in one of our foster homes and we have not met him, we are assisting his owners with finding him a new home. 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. No other animals, no small children in the house. - Has had multiple professional training experiences, all successful. Quick improvements in training sessions. 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. Selectively reactive with intact males. - No cats is best. He is ok with cats if the cat leaves the dog alone. He lived 2 years with a male cat and they kept to themselves and lived peacefully. - Not socialized around kids. Unknown. - Resource guards around main meals and high value treats, but not with training treats. Very easy to train (food motivated). Does not protect empty bowl. - One bite due to mishandling by his previous owner. The dog was nervous around a stranger and the previous owner did not intro or deescalate then dropped leash. After a professional reactivity evaluation, a trainer assessed him to be safe and not serious about bites. - Previous owner got him as a puppy from a friend’s litter.
