Story
Meet Gourd! Gourd is a friendly, playful boy who is ready to find his forever family! This lovable guy has plenty of personality and is always happy to make new friends. Whether he’s enjoying playtime, spending time with his favorite people, or working for a tasty treat, Gourd is ready to make the most of every day. He has so much love and fun to bring to a home of his own, and now he’s just waiting for someone to give him that chance!One of the quickest ways to win Gourd over is with food! He is extremely food-motivated, which is fantastic news for adopters looking to teach him new skills and work on his training. Treats are a great way to keep him engaged and help him learn, but his enthusiasm for snacks means his future family will need to be mindful about keeping food out of reach. No unattended meals or tasty treats left on the counter for this clever boy!Gourd is also a very tolerant pup who handles being touched well and does great during vet appointments. These are wonderful qualities that can make routine care and handling a much easier experience for his future family. When it comes to walks, Gourd does reasonably well on leash, although he can get a little jumpy when his excitement takes over. Since he is a large, strong dog, adopters should be physically prepared to manage his size and enthusiastic movements. With consistency, patience, and continued work on his manners, Gourd has the potential to become an even better walking companion.Are there any canine friends in Gourd’s future home? He is friendly with other dogs and enjoys playing with them! He would love opportunities to socialize and have fun with compatible doggy companions. As with any dog, introductions should be done thoughtfully to make sure everyone is comfortable and gets along.Gourd would do best with a family who appreciates his playful spirit, can comfortably handle a large dog, and is excited to continue helping him learn and grow. He has so many wonderful qualities to offer, from his friendly nature to his love of treats and playtime. In return for a little guidance, some tasty training rewards, and plenty of affection, Gourd will bring lots of fun and companionship to his lucky adopters.If you’re looking for a big, lovable buddy to share life’s adventures with, Gourd could be the one you’ve been waiting for! Come meet this sweet, spirited boy and see if you’re the family he’s been dreaming of.

Story
Bruno Mars came to the shelter as an owner surrender along with his three young puppies, and he was the sweetest, most gentle dad to them. Bruno Mars is a sensitive boy who can be very shy when meeting new people, but once he learns that he is safe with you, his affectionate side begins to come out. Loud noises and quick movements can still startle him, so he would benefit from a patient home that allows him to build confidence at his own pace. Bruno Mars has already come such a long way and continues to grow more comfortable and trusting. Bruno Mars is also good with cats. Underneath his shyness is an incredibly sweet, gentle dog who just needs someone willing to give him the time to feel safe. Good with women: Yes Good with men: Yes Good with kids: Yes, best with older children as he is shy at first Good with other dogs: Yes Good with cats: Yes House trained: In progress, he sometimes has accidents overnight at the shelter Crate trained: Yes Energy level: Low/medium Can be handled/touched: Yes, but is very shy at first Barker: No Flight risk: Possibly in the beginning until he bonds with his family and feels safe Food Aggressive: No Walks on leash: Yes Leash reactive to people or dogs: No Rides well in car: Yes Destructive: No Needs a home with a yard: Yes Needs a home with another dog: No Can live in an apartment: No Please visit our website niagaradogrescue.com to learn more about this amazing pet and to see other available dogs.

Story
Ollie is an 2+ year old Bull Mastiff who was surrendered to us after living on a farm . 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 is fine with other dogs, but is better suited in a home with female dogs or no other dogs, he has not had much exposure to male dogs. Ollie is best suited in a n adult only home 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 apparently growled at the children in his previous home. We prefer a rural type home with a secure fenced in yard . He is such a sweet and gentle giant with adults. He is walking well on leash but may be better on an "Easwalk Harness" because if he sees another person he gets excited and pulls hard and is strong. Ollie is vaccinated, microchipped and is neutered. If interested, please send us an application https://form.jotform.com/201994848495070 or email- havenoftheheart1@gmail.com
