Story

AVAILABLE BY APPOINTMENT! Hi there, my name is Atticus and I'm a 9-month-old, neutered Mastiff / Pitbull mix that currently weighs about 55lbs. I'm still a growing boy and will be around 70lbs as an adult. I'm a sweet and friendly guy that likes to ponder life's big questions. Where do the treats come from? Will I be the bestest boy? How many naps can one take in a day? I hope to answer all of my questions in my new home. I'm a food motivated pup that loves to learn. I'm currently working on impulse control, I'm a high energy boy who doesn't know how big he is. I'm hoping for a family that's prepared to continue my training, give me lots of exercise, and wont be upset if I jump up on them. I may be big, but I'm still a lap dog. I hope to find a family that is able to philosophize with me. For more information, just ask Customer Service about Atticus! ID# A957791 Since I’m not at the adoption center, you can make arrangements to meet me by submitting your fully completed Adoption Profile Form to adoptinquire@peninsulahumanesociety.org and a staff member will call you to conduct a phone interview before making an appointment to meet me in person. You must be 18 or older to submit a profile.

Story

Theo was found as a stray. I got him as an emergency foster and he’s been such an easy to train, loving, timid boy. Shy at first and will hide until he knows the coast is clear, once ready to say hello he is goofy. He moves very slowly and hardly makes a sound around the house. If he sees or hears something suspicious he gives a deep, gentle bark to let you know. When it’s dinner time you get to see how he bucks like a bronco before he sits politely and waits for the, ok, to eat. At 2 years old and 116lbs he still has a bit of growing to do. He has had absolutely no issues in the last year I’ve had him. He gets along with all the dogs and lets you bath him and clip his nails with no fuss. Large breeds like him take longer to mature so even though he is technically an adult, he’s still a big baby that needs guidance to build confidence. Looking for a perfect home should be easy. He loves cuddles, treats, and going out for ‘sniffaris’

Story

Rambo is a wonderful 5-year old Boxer Mastiff mix looking for his forever home. He is a very well-behaved and loyal companion with lots of desire to play outside with other dogs. He was rescued being blind on his left eye, but that does not stop him from being full of personality and spunk. Rambo has been neutered, microchipped, and all if his vaccinations are up to date. He would be a great addition to any family looking for a large dog, preferably in a household without small pets or cats. He weighs about 60 pounds. Please contact me to set up a meet and greet or if you have any questions.
