The company, which is the largest independent pet franchise in North America, is adding to its portfolio.

Pet Supplies Plus and Wag N’ Wash ended the year with 115-plus new store agreements in development. With more than 640 stores in 41 states, Pet Supplies acquired the self-wash, grooming and natural pet food franchise, which has some 15 locations in February last year.

One of the new developments is the first dual-branded multi-unit agreement. This will include two Pet Supplies Plus stores along with one Wag N’ Wash location.

“As pet spending continues to rise, franchise candidates are seeking to invest with our strong growth brands featuring the lowest royalty fees within the pet industry and best-in-class corporate support,” said Chris Rowland, CEO of Pet Supplies Plus and Wag N’ Wash. “From our full-service, legacy brand to our up-and-coming dog wash and grooming franchise, we offer simplified business models to grow alongside the rapidly growing service category.”
