Story
This is Bepsi. He is a young dog that was found alone in the rain in Northern Manitoba.When he was saved, he was severely injured, with a massive abscess above his right eye. He was taken to the emergency vet, where it was drained and cleaned, but unfortunately he also suffered a fractured skull. It is presumed that he was attacked by a much larger dog. Bepsi is missing the right half of his brain and will be a special needs dog who may have a limited ability to do normal "dog" things but still deserves all the love. He loves car rides, chewing and baths. He cannot play normal games like fetch or tug of war but put a toy in his mouth and let him spin and he will have a blast. He loves cuddles and playing with other dogs who can be delicate with him. Due to his traumatic brain Injury he obsessively spins and will require special care for the term of his life. He needs reminders sometimes to stop spinning. You can pick him up, hug him, hold him or give him a toy to chew on in bed. He responds to clicking or snapping sounds to help stop spinning or move him forward. Baby gates, supervision and safety protocols are advised. His life span is not suspected to be affected. Weight: ~40lbs Good with men: yesGood with women: yesGood with kids 0-6: noGood with kids 6+: yesGood with dogs: yes, but with supervision because he doesn’t have the reflexes or awareness to move out of their way if they are running Good with cats: yes, Cat friends are perfect for him because they can play with him without restraint or worry of sizing or hurting him.House trained: yes, but has frequent incontinence due to traumatic brain damage. Requires diapers or pee pads and frequent potty breaks. Requires consistent skin care to avoid break down or urine burns due to incontinence.Crate trained: yesResource guarding: noWalks on a leash: he gets tangled easily due to spinning, gets exercise by other means.Energy level: lowRequires detached/single home: noSeparation anxiety: cannot be left alone for long term. When he is left alone for short terms, he shows no sign of separation anxiety Barker: averageIdeal Home: someone who works from home or can be home with him throughout the day. Doesn’t require much space. Would be a great ride along buddy for a driver or if he could attend work with owner.Medical:Bepsi is missing the right half of his brain and requires special needs care in areas stated above. He may require ongoing medication to assist with relaxing or reduction of spinning.

Story
*Fostered in Guelph*Apply at rebeldogrescue.com*APPLY TO FOSTER TO ADOPTGabriella is a friendly, easygoing dog who walks well on leash, takes direction well, and has been social with everyone she’s met.When she arrived in rescue, Gabriella was very underweight and suffering from untreated flea allergies. With proper care, a quality diet, and allergy management, she has made great progress and continues to do well.Gabriella enjoys spending time with her people and other dogs, but she’s also happy to relax independently. She would do best in a home with another well-mannered, social, and confident dog, as she thrives with canine companionship.More than anything, Gabriella is looking for a safe, loving home where she can continue to thrive.Name: Gabriella Breed: Bully mix Age: ~2 yearsWeight: ~30lbSex: Female, spayedColour: GreyMedical: Flea allergies upon intake; suggest fish oil supplement long term Good with men: Yes, friendly and outgoingGood with women: Yes, friendly and outgoingGood with kids 0-6: Unknown, not tested - yes, based on temperament. However - she is strong and playful and new introductions to children should always be supervised.When the dog meets new people she…Approaches happily/outgoing, Happy tail wagGood with dogs: Yes, happy to co-exist with other dogsHow does this dog react to meeting new dogs? Loose body language, Neutral - will say hello nicely, Depends on how the other dog is actingWhat type(s) of dogs does this dog prefer/be best with? Gabriella has confident energy - but takes the copilot role when the other dog takes the lead. She may be too much for teeny tiny dogs but is happy to play with other friendly medium + dogs as long as proper introductions are done.Good with Cats: Unknown, not testedCrate training: Enters crate willingly, Settles after some barking/whiningHouse training: Almost perfectly house trained - about 90% thereResource gaurding: None seenWalks on a leash: Walks wellEnergy level: Medium - enjoys regular exercise and adventures as well as relaxing calmly in the homeAreas to work on: She is a well rounded dog that is certainly " confident " by most peoples standards, but she does seem to seek comfort from outside sources rather than internally. The further she is removed from the shelter environment the more she will start to feel a sense of calm and peace internally.Any noted separation anxiety? None seen. Barker: Average

Story
APPLY TO FOSTER TO ADOPTFostered in Waterdown Ontario Meet Ruby, a stunning reddish-brown Australian Shepherd mix with a heart as big as her energy for life! Ruby is the perfect blend of intelligence, athleticism, and affection. This sweet, gentle girl has already proven herself to be a great foster pup, and now she’s ready to find a forever home where she can truly shine. Ruby is friendly, quiet, non-destructive, and loves being part of the action - whether that’s playing with toys, engaging in training, or joining her doggy daycare buddies twice a week (where she’s thriving!). She walks nicely on leash, is house-trained, crate-savvy, and has no medical concerns. Ruby would do best in an active, adult-focused home that can provide her with plenty of exercise, enrichment, and continued training. She’s highly toy-motivated and would excel in dog sports like agility, dock diving, or frisbee. She has some herding instincts and a touch of excitability, so she’d benefit from a home that appreciates her drive and is excited to help her channel it into fun, structured activities. Ruby gets along well with other calm dogs, is friendly with people (though she may be a bit shy with men at first), and is eager to bond deeply with her humans. If you’re looking for a loyal, smart, and active companion to share your adventures, Ruby might just be your perfect match!Name: RubyBreed: Australian Shepherd X Mystery Mutt!Age: ~1.5 yearsWeight: ~35lbSex: Female, spayedColour: Reddish brownMedical: No concerns Good with men: Yes, but shy and warms up quicklyGood with women: Yes, friendly and outgoingGood with kids 0-6: Unknown, not testedGood with kids 7-15: Unknown, not tested - suspect yes Has this dog ever bitten or attempted to bite?
