The pack was spotted around Clearview, Bellview, Scheidy’s, Fairview, Victoria, 329 in Egypt, and more.
The original dark brindle dog has been around since May and caused no harm since then. The others, a solid gray dog and dark brown/black dog, do not have collars and are the aggressive ones. They've been traveling in a pack together.
