Grape Growing Pruning

My vines stop producing?
Three years ago I had given grapes. Last year we had a late frost in spring and I was not expecting much, but I did not. This year, they produce nothing at all. I cut them each year and grow crazy. I can only figure Whats up. My dogs go spend time around because they love the shade. Urine Could have something to do with them do not produce.
if your plants grow well, and then the dogs have nothing to do with your problem, some grapes produce the best in two years, alternating,,, The weather here has been really damaging our garden and vineyards. spellls along the track dry and then too much rain, etc,,,
