PUPSI began in 1993 with a 500 square foot space. Cary, a facility measuring 500 sq. We were primarily training dogs at that time. Daycare wasn't available, but boarding was not an option. Dogs who were in training would be allowed to "socialize," which is an important aspect of dog training. This principle still holds true at PUPSI. People loved the tired dogs and wanted to know if daycare could be offered. As PUPSI grew in popularity, so did our clients. Eventually, these clients started to ask for grooming, boarding and other services. PUPSI eventually expanded.
