Rajah

Mastiff

Male, Young

South Plainfield, NJ

Size

(when grown) X-Large 101 lbs (46 kg) or more

Details

Good with kids, Needs experienced adopter, House-trained,

Story

Rajah is a 110-pound Bandog who will be 2 years old on July 28th. He is deeply devoted to his family and is incredibly affectionate. Making the decision to rehome him has been heartbreaking, but we recognize that he needs an environment better suited to his breed and temperament. Rajah is a powerful guardian breed with strong protective instincts and is aggressive toward unfamiliar people. He is not a dog who is comfortable meeting strangers or being introduced to new people casually. We invested in professional training, but his natural guardian instincts remain. He will need an experienced owner who has previously owned or handled large guardian breeds and understands how to safely manage a dog with stranger aggression. We have had very limited exposure to other dogs and cats, so we cannot confidently say how he would do with them. There is no adoption fee. Our only priority is finding the right, experienced home where Rajah will be safe.

Jeffrey

Mastiff/Shepherd (Unknown Type)

Male, Adult

Jackson, NJ

Size

(when grown) X-Large 101 lbs (46 kg) or more

Details

Story

Jeffrey, Mastiff/Shepherd mix, Brindle, Male neutered, 2 years old Jeffrey is a very handsome boy! He may take a little time to warm up, but once he does, he is very sweet and enjoys getting attention. Jeffrey is a very big boy and is very strong when being walked on a leash. He needs a family that can handle a dog of his size and is experienced with his breed. Jeffrey does not seem to enjoy the company of other animals and would do best as the only pet in the home. He also needs a home without children, as they would be too much for him. **This dog is at the Ocean County Animal Facility North located at 615 Fremont Ave, Jackson NJ (off of Hope Chapel Rd). All dogs are spayed/neutered, micro-chipped, and have age appropriate shots.** To adopt our dogs you must come to the facility with your entire family, including dogs, to meet with our staff and the dog you are interested in. We are open to the public seven days a week between the hours of 1pm and 4pm. Please call our facility at 732-657-8086 for more information about any of our pets! June 27, 2026, 4:57 pm
