We put in an iron fence in our backyard and we love it! We mainly put it up so that my 2 toy poodles could run around the backyard freely an not have to be watched all the time. The fence was put up about a year ago, with NO problems.....Now, and we are not sure why, but the dogs have now realized that they can squeeze through the bars......Is there anyone that can fix, or make something for the bottom of the bars so that my dogs can't get through the fence anymore??
