Story
You can fill out an adoption application online on our official website. Fill out an Adoption Application  HEADLINER: Moose HISTORY: Moose came to us very underweight and with marks showing he was locked in a crate with no padding for most of his life. He never had basic training although his foster is working on it, and he is eager to learn. Despite his rough life, Moose is such a love. He is very patient waiting for his food and takes treats very gently from your hand. He loves people, men and women alike. PERSONALITY: Moose is a silly guy that loves showing you how flexible he is by twisting himself into all types of silly positions whether it be sleeping half on and half off the sofa or fully stretched out on his back with paws up in the air. He is very nimble and can jump up on beds or get in the car easily. He loves car rides. He is very friendly and has had no issues meeting the foster's 6’3” college sons nor friends and neighbors. The vet and vet techs all loved him, and he was such a good boy getting blood drawn and getting vaccines. They referred to him as “a real gem”! Moose is gaining weight and has the softest chocolate fur. And he has not shed at all! Vet says he will most likely be 120lbs when he reaches his ideal weight. Moose has separation anxiety and does not like to be left alone at all. Using a crate is not an option given his past. He wants to be with his person, and he will need a patient adopter to help him overcome his anxiety. FAVORITE ACTIVITIES: Moose loves to chew on toys, go for car rides and take walks. He is getting better on a leash using an easy walk harness but needs continued leash work. Moose has short bursts of energy and then as a typical mastiff, needs a nap. He sleeps at his foster's feet or on the sofa while his foster works from home and is the perfect office companion except for the occasional snoring. MEDICAL ISSUES: Moose is currently being treated for Lyme. He will be neutered and have entropion surgery soon. No ongoing issues. WHAT WOULD BE THE BEST KIND OF HOME: Moose does not do well left alone. He needs a home where there are people home most of the time and are willing to work on his separation anxiety without using a crate. He also needs basic training and someone who has the patience to teach him manners, but he is willing and eager to learn. Moose is very strong and will need continued leash work. He has improved using the easy walker harness in a short period of time. He just needs someone to train him, and he will be the best companion. Given his needs for training, an experienced dog owner would be best. Moose doesn’t know his size or strength and would do best with a family without young children. He would do great with teens. He loves the car and will want to go wherever you go. Moose did live with another dog, but he has not been him with dogs or other animals. It was recommended that Moose not be allowed around chickens.

Story
You can fill out an adoption application online on our official website. Fill out an Adoption Application HEADLINER: Tina (aka Carter) HISTORY: Owner surrendered to shelter after being locked in a barn stall with other dogs for unknown  amount of time. Tina shows signs of physical abuse by previous owner who was an elderly man. PERSONALITY: Tina is the kind, soft and adoring. She is the perfect best friend with the most beautiful eyes and loving gaze. She’s cautious in new situations and can spook with fast movements. Loud voices trigger a fear response in her and she will drop to the floor and try to disappear. If you grab something quickly she will drop her head and squint and brace for impact. Her fear of being hit has diminished to almost nothing at this point as she was very willing to trust us. Tina is quiet as a mouse unless she hears an unusual noise outside, she will alarm bark once or twice making her an excellent guardian. Tina is perfectly house trained, doesn’t need a crate, sits/waits for food and to be leashed and go outside. Her manners are impeccable. She walks perfectly on leash. She greets you with a thumping tail and a big yawn and a sweet little prance. She has the cutest zoomies after she goes potty outside! Because of her past she shows scars on her face from probable dog fights. She is not interested in living with another dog, however she loves puppies. Tina had a litter of 4 and 3 passed away. She was a wonderful caring mom. She just doesn’t want to be forced to interact with another adult dog. She also isn’t a good candidate for cats, she wants to smash them unfortunately. Tina is the most perfect textbook example of a Mastiff. She’s 175lbs of love, adoration, snuggles, drool, and deeply devoted. Her life has been so tragic and harsh but she has been so trusting and loving towards her foster parents. Tina is quietly protective of her person, she has put herself between her foster mom and big scary horse that she wasn’t sure of, gently pushing her person away and sitting in front to keep an eye on the suspicious animal. She hops around joyfully every time we come in her room, play bites so gently and plants her giant head on your lap any chance she gets. This is a snuggle, snack and nap kind of girl. She loves toys and nurses her stuffed toys like a baby. Tina is someone’s once in a lifetime dog. She is the kind of dog you hope for and never forget. The perfect partner and very best friend you could ever have. FAVORITE ACTIVITIES: Snacks, big belly rubs, wallering her favorite person, naps, gnawing bones, hopping like a deer in the yard, being talked to like your teenage BFF (she loves gossip) and gets scratches on the soft spot behind her right ear. MEDICAL ISSUES: none WHAT WOULD BE THE BEST KIND OF HOME: Tina’s new best friend should have a comfy low couch with pillows and lots of time to spend chatting with her. She is very engaged. No other pets please, but this doesn’t make her a mean dog. Honestly who needs another one when Tina is the whole package anyway?! A fenced yard isn’t necessary but she has to be on a leash when outside as she will chase a cat or squirrels. Big kids would be just fine. We have no way to know how she would be with very young children but loud voices and quick movements are scary at first so best not to put her in that position. Mostly we want someone who can see what a perfect gift she is and adore her as much as she will adore that person.

Story
Welcome Gelato This sweet boy joins us from the Northern Ocean County Animal Facility in Jackson. He was surrendered to the shelter with stomach problems and was grossly underweight. Thanks to the dedicated care of the staff and volunteers, he started to gain some weight and is feeling much better. Gelato is a 3-4-year-old Corso/Mastiff mix who is as sweet as his name! He is a friendly, social boy who has a solid sit command and takes treats very gently. He absolutely loves people and enjoys attention. He will need someone who will continue to work on training as he is strong on leash and is eager to learn more commands. Due to his large size, he is recommended for a home with kids 11 and older. While he did okay on his dog test, he might be too much for most dogs. He is playful and goofy so a dog who could handle his energy. No kitties for Gelato! He is UTD, microchipped and neutered. He will still need plenty of TLC while he gains weight and continues to get healthy. We would love to get him into a home! Please don’t let him wait long. If you’re interested in fostering or adopting Gelato, please apply at pittiesandpals.com.
