"We're not making up the difference yet," he said. "But we're seeing a different customer base that we have never had before."
That customer base isn't exclusive to Pennsylvania either - pet ownership in the U.S. has more than tripled since the 1970s and there's a greater desire to help pets in need. Considering the problems associated with some breeders and puppy mills, more and more pet owners are looking to adopt, not buy.
Giant chains like Petco and Petsmart have started holding adoption events in recent years, while the number of shelters increases each year. And according to HSUS, there are now 6 to 8 million pets entering shelters each year, every one of them looking for a new home.
