Certain Pacific islands whose maritime settlers did not bring dogs, or where dogs died out after original settlement, notably: the Mariana Islands, Palau, Marshall Islands, Gilbert Islands, New Caledonia, Vanuatu, Tonga, Marquesas, Mangaia in the Cook Islands, Rapa Iti in French Polynesia, Easter Island, Chatham Islands, and Pitcairn Island (settled by the Bounty mutineers, who killed off their dogs in order to escape discovery by passing ships).
Amongst apprenticeship programs and other hands-on training activities, Petco pet stylists who are trained from within the company are required to attend and pass Petco's comprehensive 12-week Pet Stylist Apprentice & Certification academy program. In addition to hands-on grooming training with a Petco-certified pet stylist mentor or instructor, all participants receive instruction in health, safety protocols and grooming salon operations. At the end of the program, candidates must pass a technical skills assessment in order to become a Petco Certified Pet Stylist.
Pets with special needs: Our salon safety protocol is maintained to the highest safety standards. Express service is available for pets who prefer to be hand dried only. For pets with flatter faces (also known as brachycephalic), your stylist will recommend this option as this will greatly decrease the amount of time your pet will spend in the grooming salon, and may be a better option for the health of certain breeds. Please note that we cannot accept wolf hybrids at this time, due to vaccination limitations.
