Story

Meet Benjamin 💙 A gentle giant with a heart of gold Benjamin is a Mastiff mix with the soul of a sweetheart and the body of a cuddle-loving couch potato. He’s playful and goofy once he feels safe, but meeting new people can take a little time—he prefers to build trust slowly and thoughtfully. When he does, you’ll have a loyal Velcro dog who wants nothing more than to be by your side. A few things about Benjamin: • A certified gentle giant—sweet, loving, and wonderful with kids 🧸 • Equal parts couch potato and adventure buddy—happy to nap or join you for walks 🌿 • A true attention hog and Velcro dog—he loves being close to his people 💙 • Playful and goofy once comfortable, with a big personality and even bigger heart 🎾 • Food-motivated and eager to learn—training is going great and he’s a straight-A student 🍪 • House-trained and crate-trained—he knows the routine and does well with structure 🏡 • Learning leash skills and improving every day with positive reinforcement 🐕 • Enjoys car rides and makes an excellent passenger princess 🚗👑 • Good for vet care and handling when he feels safe and supported 🩺 • Shy and a bit nervous in new situations—multiple visits are required to help him feel secure 🌱 • Would thrive in a patient, loving home that lets him settle in at his own pace Benjamin is the kind of dog who bonds deeply and loves wholeheartedly. Give him the time to feel safe, and he’ll repay you with loyalty, affection, and the kind of companionship that only a gentle giant can offer. 📍 The Center for Animal Health and Welfare PA Kennel License #02941 1165 Island Park Rd, Easton, PA 18042

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.

Story

Meet Montgomery. Montgomery has traveled a long road to get here. At 4–6 years old, this 93-lb Mastiff mix carries the scars of a life that hasn’t always been kind — but his heart? Pure gold. Despite everything he’s been through, Montgomery is the definition of a gentle giant. While in a foster home, we were able to learn more about Montgomery. His dream life is simple: some nice walks to stretch those big legs, and a warm, cozy bed to curl up in at the end of the day. Initially, he should go to a home with no other pets and an adult only home (teenagers may be ok but he prefers quiet). This may be Montgomery's first shot at indoor living, so everything is new to him and he becomes overwhelmed. Once things quiet down, the real boy flourishes and he starts playing with toys and relaxing. After all he’s endured, he deserves every ounce of comfort and care. If you’re ready to make room for a truly special dog, Montgomery is ready to give you all the love in return. We will not review applications with current pets or young children at this time.
