I have been sending Junior, my 11 year old cocker spaniel here for grooming for years! They will always respond to my requests and appointment bookings promptly!
Not just that, they also update me on the condition of his skin, fur, ears etc, after each session and recommend me products (not asking me to buy from them) and ways to treat/care for junior myself.
What's more, they also have transportations to and fro your place if you don't have a form of transport for your furbabies:)
