PASADENA, Calif. – Gourmet hot dog, sausage and burger concept Dog Haus announced its restaurants will start using all natural, vegetarian-fed pork, chicken, turkey and beef raised without antibiotics or hormones. In addition, Dog Haus hot dogs and sausages will now be nitrate and nitrite free.

The growing chain currently has 26 locations in six states with more than 450 additional restaurants planned in the next several years, including expansion to the East Coast. 

"There is an ever-growing public interest in not only paying close attention to what we regularly consume, but where those ingredients come from, how animals are raised, and what effect these elements have on us," said Dog Haus partner Hagop Giragossian. "Dog Haus has been deeply committed to creating food that not only tastes phenomenal, but allows our guests to have peace of mind about its uncompromisable quality."

The chain offers its customers certified humanely-raised, hormone- and antibiotic-free Creekstone Farms Natural Premium Black Angus beef, premium Idaho Duroc Heritage pork and hormone- and antibiotic-free, vegetarian-fed chicken and turkey. 

Dog Haus was founded by Giragossian, Quasim Riaz and André Vener in Pasadena, California, in 2010.
