Pet Spa offers a full-range of pet-styling services, as well as small-animal daycare. The shop's innovative design lets owners view their pets being washed and styled, while the pets in line enjoy a friendly, cage-free environment. Pet Spa also features a small boutique carrying a wide range of pet styling products, as well as clothes and leashes. In business since 2003, the shop is owned by long-time Somerville resident Theresa Sammon.
