More than 5,800 postal employees were attacked by dogs last year, and the pandemic was partly to blame, says the U.S. Postal Service.
E-commerce surged when shoppers were stuck at home, meaning more packages being delivered to residences.
And more people, including children, were at home to open the door for deliveries, giving pets more opportunity to escape.
Plus, there were simply more dogs, as "pandemic puppy" adoptions soared last year.
Why it matters: It's National Dog Bite Awareness week and the postal service wants to remind dog owners to secure their pets. This year’s theme is “Be Aware: Any Dog Can Bite.”
Houston ranked first in dog bites, with 73 carriers attacked. Chicago, Los Angeles, Cleveland and Denver rounded out the top 5 for most aggressive dogs, according to USPS.
What to watch: In the era of Big Delivery, reports of dog attacks could be expected to rise among Amazon, UPS and FedEx delivery personnel, too, though a UPS spokesperson says the company hasn't seen an increase yet.
The bottom line: Both UPS and the Postal Service say if a driver encounters an aggressive animal, they will not deliver the package, and you'll have to pick it up from their facility.
