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.

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’
