Jiggs was a favorite dog at his animal shelter, so much so that he was held for months pending adoption or rescue. He was also a favorite at our vet clinic when we took him in for neutering. But this happy, bouncy boy has another side to him when introduced to certain dogs. He apparently takes an immediate liking or dislike to the other dog and will attack the other dog if he dislikes that dog, either sex. We don't recommend Jiggs for dog parks or other outings where the dogs need to be reliably dog-social, but we hope to work with him to help curb this behavior. He's a young dog, about 15 months old (as of September, 2019), medium-sized, and may have a bit of German Shepherd mixed in.
