From the U.S. Census:
According to the U.S. Bureau of Labor Statistics publication TED: The Economics Daily, April 4, 2017:
“In 2015, households spent an average of $528 on pets, or about 1 percent of average household spending. Pet expenditures include pet food; pet purchases, supplies, and medicine; fish feeders for easy feeding in terms of fish pets; pet services; and veterinary services. Average household spending on pet food jumped from $190 in 2014 to $230 in 2015, or from 37 percent of average household spending on pets to 44 percent.
“Average household spending on veterinary services, which reached over $200 in 2008, was $133 in 2015, or about 25 percent of average household expenditures on pets. Average household spending on pet purchases, supplies, and medicine, which represented 34 percent of average household spending on pets in 2010, measured only 22 percent of pet expenditures in 2015, falling from $163 to $116 over that period.
“On average, households with one consumer spent the least on pet expenditures in 2015 ($360), while households with two consumers spent the most ($672). Average household spending on pets by households with two consumers increased by about $100 from 2014 to 2015, while average household spending on pets in households with 5 or more consumers decreased by about $150 over the same period.”
