Won't street walk anymore

My 5 year old standard schnauzer "Boris" has suddenly stopped wanting to walk in our street. He's fine in the garden and car to go to a field but outside our house he literally has put his brakes on and will not be led anywhere. I know he's not ill or in pain, he is still the same as always inside the home, just will not be led on a walk down our street. Nothing ha happened that I am aware of to scare him, has anyone else experienced this? Could there be something I am missing or maybe just a very stubborn bog. I've believed that you should never pull or drag a dog to force a walk as this can do more harm but is he starting to rule me and actually clever with nothing actually wrong? Any tips would be appreciated.....I am missing my walks😟
