Each shop needs a complete Google Business Profile: the pet store category, grooming as a service, accurate hours, shelf photos and products listed by species. If you deliver, set service areas that match where you really go, and link to a page that lists them.
Owners often search from home for delivery rather than a visit: "pet food delivery indiranagar", "cat litter home delivery andheri". One well-written delivery page plus your profile's service areas usually does more than a set of near-identical area pages that Google treats as thin.
Searches mix Hindi, English and regional languages: "kutte ka khana", "billi ka khana online", "paas mein pet shop". We use these phrases in your profile description, posts and delivery page where they read naturally, and stores with branches in several cities get a profile and delivery page for each.
