As a rescue, we see a lot of dogs who lack social skills with other dogs. Some of them show what appears to be aggression, and can be dangerous to other dogs, when they aren’t truly aggressive by nature. Katie was such a dog. Katie is a black Great Dane, very tall, very underweight and a stray at a rural shelter. She was friendly with people, but wildly aggressive to other dogs. Even the sight of another dog had her barking, lunging and snarling as she tried to attack. If unable to bite the object of her fury, she would spin and bite herself. Truly a disturbing sight. If fact, Katie had been adopted out to a person who promised to keep her separate from other dogs but it didn’t work out because she got so wild at just the sight of another dog. She was returned to the shelter.
