Our Ridgeback, Loki, lives up to his name. He is not a dog to be kennled. He will either break out of a fenced/ kennled area or hurt himself trying. The installation is very easy and will take a weekend of your time (or my husband's in this case, lol). We did have to purchase an extra spool of wire for our yard. There is a 30 day training guide.... our puppy caught on the first day attempting to chase a squirrel in the neighbors yard. Great purchase!
