Chennai to Coonoor With a Dog
Around 13 hours of driving, roughly 610km. That is a long day and most people split it over two.
Chennai to Coonoor and Coonoor to Chennai are one journey, so everything here applies whichever way you are pointing.
Getting there by road
Roughly 610km and about 13 hours, traffic depending. About 7 hours from Bangalore and 4 from Coimbatore. The climb from Mettupalayam has 26 hairpins in roughly 20 km, which is the single most reliable way to make a dog carsick in south India. Empty stomach, window cracked, and a stop at the base before starting up.
Railhead if you would rather not drive: Mettupalayam for mainline trains, then the road climb. Coonoor has a Nilgiri Mountain Railway station, though it is not practical with a dog.
Leaving Chennai
Coonoor lies south west of Chennai, roughly 610km by road. Chennai exits well on the main highways, and the heat is the real planning problem rather than traffic. Leaving at dawn matters more here than in most Indian cities, because the middle of the day is genuinely dangerous for a dog in a car.

Coonoor in one paragraph
Quieter and greener than nearby Ooty, with tea estate walks. Same Bandipur and Mudumalai reserve crossing applies on the drive, so travel in daylight.
The full Coonoor guide sets out the terrain, the restrictions and the hazards worth knowing before you arrive.
Veterinary access at the far end
Reasonable. Coonoor and Ooty both have private clinics, and the veterinary university campus at Ooty is a useful backup. Better than most hill stations on this list.
Worth ten minutes in Chennai rather than an hour of panic at the other end. Emergency vets by city.
Timing it from Chennai
Hot and humid for most of the year, which means heat risk runs far longer than the April to June window that applies further north. Skin problems are constant.
The northeast monsoon around October to December brings flooding in parts of the city, and with it water contamination risks.
Set that against Coonoor, where the advice is to go october to june and avoid peak monsoon. The overlap between those two windows is your actual travel season, and it is usually narrower than either one suggests on its own.
Doing this journey with your dog
At around 13 hours this is a long day out of Chennai, and most people split it. Plan the first stop before you leave, not when the dog starts complaining. Somewhere with shade and a patch of grass inside the first ninety minutes sets the pattern for the rest of the 13 hours, and it tells you early whether this dog travels well. The stop you improvise on a highway shoulder helps nobody.
