I have a chain link fence which has been in place in my yard for many years and is kind of stretched out. My new puppy, Sasha has figured out how to push her nose under the chain link where it hits the ground until she can get her body through and escape. I tried putting some cement blocks around the bottom, but it is not stopping her. Once she gets though she cannot get back in as it pushes the wrong way. Are there any stakes I can use to better secure the bottom of the fence or any other way to keep her in without replacing the fence?
