The new arrival: registration first, groomer second
If you have just landed with a pet, resist booking a groom for day two. A relocated animal has been through crating, cargo and a strange new home; give it a week or two before adding a bath and a stranger with clippers. Use the time for paperwork. Dubai requires dogs to be microchipped and registered with Dubai Municipality; Abu Dhabi handles registration through its government services under ADAFSA oversight; Sharjah and the northern emirates have their own municipal rules, often stricter about dogs in public spaces than newcomers expect.
When you do book, say it is a relocation case, and a good groomer will treat the first visit partly as an inspection: coat condition after weeks in transit, skin dryness from the climate change, ears after the flight. With no word-of-mouth network yet, comparing several verified vendors and their AED ranges side by side substitutes for the neighbourly advice you have not had time to collect.
