Dear Annie: Last year, my husband and I attended my cousin's annual summer barbecue. After we arrived, I looked for a place to tie up our dog in the backyard and noticed a few dead rats. They appeared to have been there for some time. I made mention of this to my cousin's husband, but he made no attempt to remove them even though they were only a few steps away from the barbecue pit.
I tied my dog several feet away from the dead rats. Later, when we returned home, our dog started scratching. This continued for several days until we noticed his fur was falling out. I believe he contracted mange from the dead rats.
