Size L fits good for my 3 year old german shepherd. She got used to wearing it very fast! Fast to put on and dog finally stays in place while driving in car.
This harness is so versatile and easy to use. I bought the medium/large size for my border collie/terrier/spaniel cross. There is plenty of room for adjustment so although my dog is on the small side it would adjust to fit a much larger dog too. The buckle fits my Vauxhall Zafira and the lead part is also adjustable so your dog can sit comfortably on the seat or the floor without the lead part pulling tight. It can also double as a walking harness. If I travel with my dog in the car I usually unclip the harness lead and clip her normal lead onto the harness. This makes it much safer as I can hold onto her as she gets out of the car. We can then walk to where we are going whilst she is still wearing the harness. I am delighted with this harness.
Purchased this about two weeks ago for Louis, our 8 month old Beagle hound. Louis absolutely hates harnesses but he seemed fine with this when used for walks...didn't get an opportunity to try it in the car as yesterday, he managed to chew his way through the fittings etc...so overall, a good product but certainly not chew-proof - and I was concerned as he had managed to get the plastic fittings off and was chewing them and could have swallowed them.
Just writing to endorse the reviewer who had great success with their collie. I too have an eight month old border collie who pulls on a collar and lead but not when wearing this harness. It is a pleasure to go for walks now. Good for the car too, fits my old Peugeot. Will be getting another as a spare soon. Excellent service from Zooplus too.
