We want a dog fence to take with us when we travel that meets these criteria:100 feet total lengthportable. I can use stakes to anchor it in the ground if necessary.3 feet tall.Does not need to be sturdy. My dog won't actually test it.as light weight as possibleas inexpensive as possibleThose portable dog playpens or plastic child super yards could do the job but getting enough of them would be expensive. I was thinking about using PVC pipe to make fence sections for structure and then use rolled garden fencing anchored to those. Do you think that would work? Or do you have better suggestions?
