I need to dogproof the veg plot - what can I use?

[StripeyKnickersSpottySocks]

We've aquired a greyhound recently and she keeps crapping on the veg plot. No amount of telling off is working. Not so bad at this time of year but I will shortly be thinking about seeds, etc.

So I need to find some sort of stakes that I can easily push into the ground and then tie some rope between them. Or has anyone got any other ideas what I could use.

Dog is a greyhound but I don't think she will jump much, so something about 2ft high should do it.

Loads of thinnish straight twiggy sticks, like buddleia prunings, or something, just shove loads of them in close together, the twigginess should put him off as they will stick in his face before he really gets very near the middle bit, and then you can just pull them out on the bits you want to work on and then shove them quickly back in.
