How do I safeguard my poor dog from stray ones,during a walk  

We have the same problem here. I cant even take my children for a walk around the block, especially if my dog is with us. We have called animal control, they do nothing. These dogs have come right up on me in my own yard, after my dog. I told the police if it happened again, I would spray the dog in the face with hairspray. They told me if the dog was a threat to me, I could defend myself. So I was out there, one early morning, and the stupid dog snuck right up on us, scared the death out of me. I didnt have any spray, but my garden shovel was handy, and I whacked it right in the head. It will still come to the edge of my property, but now just stands there and watches me. It doesnt solve the problem of being able to walk with my kids, but at least they arent on my property anymore. Aerosol hairspray is very effective, for strays that will pounce on you or your dog.

I also have that problem.There are a lot of stray dogs in our area. If they see my dog ,they start barking and howling..so I cant take him for a walk.

Dogs are strange in that way. Two dogs can meet when on the lead and want to kill each other. Walk them in the park off the lead and they can be best of pals.

Of course the dogs will sense your fear and worry and that won't help the situation but then you have every right to be fearful.

A tricky problem for you.

Could you pop your dog in the car and drive to somewhere nice for a walk?
