Why fence posts are a problem for injured animals
Fence posts have been used to keep animals out of homes.
But many of the posts are falling apart and need replacing.
The Department of Agriculture said last month that it had approved a fence to be built at the post office in Fort Smith, Arkansas, but it is unclear how long that project will take.
The department said it was still reviewing plans for another fence that will connect the post offices with a parking lot.
The USDA has also ordered fencing for the post in Greenville, South Carolina, but has not announced when that project is expected to be completed.
Some animals have been killed or injured while being held at the posts.
The Humane Society of the United States said in December that three dogs had died after being held in the posts in Alabama and Tennessee.
The dogs had been released by the USDA to a local shelter and were taken to a veterinarian who euthanized them.
The agency said it is reviewing the report to see if it can improve the safety of animals held in fences and if additional fencing can be put in place.
