I'm getting desperate for water to train in. The area where I live the soil will not hold water. I have a bowl on the front of my property that would make a nice pond but even after a downpour it is dry within an hour. Shoot, there is a small spring creek next to the pasture I train in that just disappears into a sinkhole. Do any of you have experience with pond liners? What I have seen on the web they are very expensive but I could put a couple of points out into this bowl and line it and maybe at least have a place where I could teach a young dog the basics. I figured the liner alone would cost me 6 grand but I need to get a new pup and start bringing along a new dog. I hesitate to get a new pup because I literally have no water closer than an hour and a half away. Appreciate any advice on pond building with a liner.
