Story
Ollie is an 18month old Bull Mastiff who was surrendered to us recently. He is such a quiet gentle boy. Ollie came to us with one eye but that does not stop him from enjoying life, he really wants to be in a loving home. Ollie used to live with a bulldog and he seems to be fine when other dogs walk past his kennel....and the horses too! Ollie is best suited in a home with children 16+ not only due to his size but Ollie seems to have had some trauma with children and does not do well when they are around. He is such a sweet and gentle giant. Ollie is vaccinated, microchipped and is neutered. If interested, please send us an application https://form.jotform.com/201994848495070 or email- havenoftheheart1@gmail.com

Story
Noelle💗 📣 AVAILABLE FOR ADOPTION or FOSTER-TO-ADOPT 📣 3 years old Fostered in London, Ontario Adoption fee: $500 I’m Noelle! 💖 I came from a local First Nations community, where I was living outside with my pups. But luckily, we were all brought into care on December 14, 2024, and now I’m enjoying the good life indoors, all cozy and comfy. My pups don’t need me anymore, and now it’s my turn for some extra love and attention! 🌟 Unfortunately, I tested positive for both heartworm and Lyme disease, so I am looking for a foster or adoptive home to let me relax while I go through treatment. My medical care is paid for by the rescue. I’m a total sweetheart: calm, loving, and always up for snuggling with my humans. I’m housebroken and great with kids. I’m eager to learn, and I’m pretty proud of my leash skills (they’re a work in progress, but I’m catching on!). I’ll always be near you, hoping for some pets—and maybe a snack or two (I’m very generous that way). 🍪💕 I have been with Black Hill Dog Company and I have excelled in both training and just being a dog! I’m making progress everyday and looking forward to continued improvement! I am working really hard on my social skills as well! I would love to be the only dog in the house if possible & I need a family who is willing to continue working with me and my continued training to be the best doggy ever and shine to my fullest ✨ A huge shoutout to Black Hill Dog Company for helping me transition into a lovable companion who's sure to steal your heart! 💗 I have been spayed, microchipped, am up to date on my vaccines.

Story
Hey there, I'm Rhett!  I was surrendered due to food aggression but I've been a good boy and haven't shown any signs of resource guarding at PDA. I am a sweet boy who gets along well with everyone, including other dogs. I haven't met a cat yet but I think they might make me nervous. Even though I haven't shown any resource guarding, I'd like to keep my relationship with food positive. I'm looking for someone with experience who can navigate resource guarding if needed.  Breed: Bull Mastiff/French Mastiff, approx 95lbs DOB: June 2024

Story
BREED – Bull Mastiff SEX – male BIRTHDAY – May 28, 2022 WEIGHT – 120lbs HEALTH – None TEMPERMENT - Ernie needs to be in a home with no other animals (He is territorial within his home). - People friendly, he loves everyone he meets. - Moderate-high prey drive. He is good on leash but his prey drive can kick in when he sees a squirrel/rabbit. He is not reactive to other dogs when out on a walk. - He doesn’t have food/toy aggression. - Ernie requires daily exercise, he has no problem going on an hour walk or 30 minute run, however he is a calm boy when in his home. - Requires a fence yard. He has been known to take himself on walks by himself. - Ernie is very sweet and loveable, he will always want to be near you. He is very loyal and will be your shadow, even in the bathroom! OWNER SUITABILITY - He is dominant and can be stubborn (typical mastiff) so he would therefore need someone with experience with a large breed alpha dog. - He is a large boy who doesn’t always know his own size and can be uncomfortable around small children so a home with children 10+. - He is house trained and is used to being home during the day when I am at work. - Must be okay with drool, as mastiff are known for the this. - There is a rescue fee. Please contact Jessica Kerwin at 613-850-7823 for more details.
