I have a 4 pound Chihuahua, Gracie. Gracie is a firm believer in exploration and her own invulnerability. We recently moved into a new home with a metal fence and in no time Gracie discovered she could skinny out between the metal bars - even though the bottom 2 feet of fence also have coated chicken wire, which she just climbs!
My niece told me about your product and I ordered it and have loved it. Gracie likes it because it means she can stay outside longer and without being on a leash! She hasn't managed to get out since she's been wearing her harness. Thank you, thank you for saving her life. (I know that sounds melodramatic, but the street in front of our house is a main artery for our small community and it gets lots and lots of cars daily. She is not at all car cautious!)
