Story

You can fill out an adoption application online on our official website. Hi! My name is Juliana! I'm about 4 years old, 78 lbs. and housetrained. I am timid though, so I need a special home, one with another dog (or dogs), a fenced in yard and really patient people. I'm so lucky to have a great foster home but I know my FUR ever family is out there somewhere. Julianna is spayed, microchipped, and vaccinated. Go to our website to see more pictures of her.

Story

Arlo is good with people, and he is 6 years old. He can be aggressive with other animals though. Recently he had an incident with a cat he has lived with all of his life. I work 7am to 7pm on most days, and unfortunately he is the product of a divorce. Arlo needs more room to run, more attention, and it seems that he would be better in a single animal home, however he might just need a change. He is very loving (lots of kisses/licks). This is heart breaking but unfortunately it is unsustainable and not fair to him. I would love to find him a great home where he can be the awesome dog that I truly know he is.

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).

**Please note this is pet is currently out of town pet but we will transport this pet to NJ for you when adopted. All fees listed include transport fees.** Meet Lola Danforth! She is a good dog who loves making new human friends. Lola is a loving companion who would love to find a forever home where she can snuggle up with her new family and feel safe and secure. Lola was abandoned by the side of the road but thankfully was rescued by a kind woman who took her in. Lola is looking for a family to love her, and her hilarious personality, she'll be a great addition. She would love to be the only fur baby in your home, so she can get all of your love to herself! She is around 2 years old and about 85 pounds. Lola does well on a leash if she knows you, but she can be shy at first. We arent sure what breed she is, but we think she is a mastiff mix of some sort. If you're interested in adopting Lola Danforth, please fill out our adoption application! Interested in becoming a forever home for Lola?

We put a lot of time and energy into processing our adoptions to find our babies the best fit home for them and you. Please do not submit an application if you are not serious about adopting. We are so excited to work with you to find you a new forever friend, and appreciate you working with us.For immediate consideration, please attach your application to the initial inquiry to help us expedite the process. Our adoption fee is $525. This includes their spay/neuter surgery, full (age appropriate) vaccinations, microchip insertion and registration, deworming, heartworm testing and prevention, flea and tick prevention and travel expenses. All of our dogs are rescued from local shelters and the general public. Each dog is then placed in a foster home where he/she is kept for quarantine, to ensure if the dog gets sick it can receive proper treatment. We have foster homes in the NJ/NY area waiting to receive their fosters. Once an animal has received an application or there's an adopter interested, we make arrangements for transport. If a dog is already in foster care in NYC/NJ, an adopter will be put in touch with the foster home AFTER an application is being processed.
