Property foreclosures are going up and authorities are beginning to find abandoned animals in/around the property. I saw a report of a place in Oklahoma where about 20 horses were abandoned when the owners left--the authorities did not get out to inspect for 2 weeks. Some of the horses were so weak/malnourished, they had to be euthanized.
People can keep an eye out and stop some of that. One of my dogs would have been left that way had a neighbor not told my DIL, who took the dog in.
