Story

Meet Delilah! Delilah may need a little time to show you her heart, but once she does, you’ll discover a very sweet, very snuggly girl. New people and situations can be overwhelming for Delilah, so she’ll need a patient adopter who will give her time to decompress, build confidence, and come out of her shell at her own pace. Once she feels safe, she loves attention, leans in for pets, and is happiest being close to her people. Delilah is food motivated (hot dogs are her favourite!), knows her sit, and is ready to work on her leash manners. She can be quite the enthusiastic puller, so her adopter should be prepared to help her learn some polite walking skills. She was wonderfully polite meeting another dog and may do well with a canine companion, pending a proper introduction. Her history with cats is unknown. She can potentially live with children, but older kids or dog-savvy teens are recommended. Delilah is a Special Paws girl and requires daily allergy medication, likely for the rest of her life. Her adopter will need to be comfortable providing this ongoing care. She can also be sensitive about having her paws and ears handled, so patience and respect for her boundaries will be important. If you believe that patience, kindness, treats, and love can help a nervous dog blossom, Delilah might be your girl. Give her the time she needs, and you’ll get to watch a sweet, affectionate companion discover just how wonderful life can be. Delilah is ready for her fresh start. Could you be the person she’s been waiting for? She is a special paws adoption, which means she does have medical needs that need tending to. She will be needing lifelong allergy meds, but because of this, her adoption fee is totally up to you ($30 admin fee still applies)!

Because of his size and strength, his new family must have experience living with and handling large-breed dogs. He needs: • Slow, proper introductions to male dogs • A home that understands he has had limited exposure to children • He has not been exposed to cats, so a cat-free home would be preferred • Someone who is home with him most of the time • A patient family willing to let him settle in and build trust

Story

Boomer is almost 5 years old, he is a Boerboel Mastiff. He’s amazing with kids, good with other dogs, but he is large and wants to play. He’s okay with cats, he’s never done anything to our cats but he does try to get as close to them as possible. He loves blankets and his bed. He’s a huge suck that will cuddle anytime you’ll let him. He’s pretty lazy, doesn’t like long walks or running and he can’t swim but he will go in water if he can walk. He really doesn't require a lot of effort but would be better if he had a bit of space and someone who was around more for him. He’s good in cars, and he’s good on a leash or beep collar. He’d probably do fine with an invisible fence if he was taught. We’ve had Boomer since he was a puppy, he’s never given us huge issues. He’s not good at meeting new people, but if you take the time to research the bred you can help him. Between full time jobs and the three young kids, we can t give him what he deserves.
