How to protect pet dogs from wild coyotes?

I live in suburbia, which is next to a major highway, but I can hear coyotes howling at night. My wall is only a chain link fence 4 foot. Does anyone know how I can protect my dogs? I had never thought about it, but I saw that there were coyote attacks in a nearby town. What, in any case, I can do to protect within reason? I mean, I sure I could build a wall 10 feet high with a lid to keep them out, but I'm looking for something that can really afford to do, short of forcing my dogs to stay inside all day. I have three dogs, ranging from 20-35 pounds. Is there safety in numbers? Is there such thing as a coyote-repellent? In response, Please indicate if you have official knowledge or are brainstorming. Thanks!

Dusk and dawn are the times most danger. Do can build a career on the right side of the house with a lid? Or walk the dogs leash at night? There is a high wall called Roller http://www.coyoteroller.com/home Coyote but nevertheless seems necessary 6 feet. fence to wear. We have coyotes near where I live. Each year there are newspaper stories of small dogs and cats collected in homes near the mountain. I'm not in the danger zone at this time. But I've always tried to keep my dogs safe. There are samples of urine to deter predators may Coyotes http://www.predatorpee.com/Merchant2/merchant.mv?Screen=CTGY&Store_Code=LE&Category_Code=WU Wolf Urine supposed to work. You can also install the motion sensor lights to deter. I have not used any of the products. I lived on a ranch and used 6 feet. high dog pens with lids and kept dogs at night and brought inside after it was done. Make sure your women are sterilized in their case too.
