Feb 9th, 2020 - Male Pit Bull was on the loose in the neighborhood and at Clay Park, San Diego CA. A husband and wife were with their 3 Schipperke's and a Golden Retriever in the park when the Pit Bull came and attacked one of their dogs. The couple tried to save the dog, but it wasn’t until another man intervened and hit the dog with a dog toy (stick) that the Pit Bull released the other dog.The smaller dog was killed. It was 14 years old and the couple had rescued it 4 years ago from SD Humane Society.Additional Info: A male from the apartment complex told us he was attacked by the same dog earlier in the evening and the dog had bitten through his pants leg before he was able to get away. We were also told that by the owners of the dead dog, that a young boy across the street from the park had the Pit Bull chase him and his smaller dog.The Police and the SDHS will be looking for the owner of the dog.
