PORTLAND — FetchDog, a dog accessories catalog and Internet site co-founded by actress Glenn Close and her husband David Shaw, was sold to catalog company Potpourri Group, while its former affiliate, Vets First Choice, received $4 million in funding.

FetchDog, known for its high-end dog toys and accessories, as well as its blog and charity work with dog shelters and other non-profit groups, was launched in 2007. The company received much publicity for its connection with Close, as well as Shaw, who founded Westbrook-based Idexx and currently heads investment firm Black Point Group.

The Chelmsford, Mass.-based Potpourri, founded in 1963, owns catalogs such as “In the Company of Dogs,” home decor and gift catalog “Expressions’’ and horse enthusiast catalog “Back in the Saddle.”

Potpourri did not return calls seeking comment.

In 2009, FetchDog helped launch the company that became known as Vets First Choice.

The company, which was spun off two years later, provides home delivery of veterinary medications and food. It allows veterinarians to provide prescription medication and food directly to customers overnight, as opposed to having clients get the medicine from a drugstore or online retailer. It targets the $6 billion market for veterinary medications and diets.

Vets First Choice, now the largest online veterinary partner-pharmacy and marketing services company, received $4 million in financing led by Polaris Venture Partners.

Existing investors, including Borealis Ventures, Harbor Light Capital, Shaw and Black Point, also participated in the funding.
