“Our mission here is to get as much out of the animal as possible,” said Jake Dickson, the owner of Dickson’s Farmstand in the Chelsea Market, where Ms. Wiseman shops for her dogs. “Both in terms of profitability, but also philosophically — doing honor and justice to that animal.”

Every Wednesday, 6,000 pounds of meat arrives at Dickson’s from farms in the Hudson Valley and in Schoharie, near Albany — four steers, and up to nine pigs and seven goats or lambs, are all broken down by hand. Fresh meat lands in the display case and is also turned into charcuterie, while trimmings are churned into ground meat and sausage.

“The dog food is kind of taking it to the next step,” said Mr. Dickson, 31, who demonstrated the “nose to tail” sustainability aspect of Farm to Bowl, his new dog food operation, by spreading out an array of animal parts on brown butcher’s paper. The paper quickly turned pink as it soaked up blood from hearts, tongues and livers. But the meat mélange also included a generous slab of New York strip, which, if it had not been faintly oxidized, Mr. Dickson said, would have sold for up to $34 a pound.

Like other butchers tapping into this niche dog food market, Mr. Dickson said that while offal and other cuts were perfectly safe for humans, he used to throw them away, largely out of cosmetic concerns or because of a surplus. Nowadays, he grinds them up, roasts them and combines them with seasonal produce.

The product is sold fresh in one-and-a-half-pound, $10 packages as dog food. He sells about 100 a week, and according to the company’s Web site, the packages last seven days refrigerated and longer frozen. At one meal per pouch for a medium-size dog, Farm to Bowl is expensive — after all, a 34-pound package of Purina Puppy Chow can be had for $23.
