Doghook was purchased for my daughter's Goldendoodle puppy that is overly friendly when anyone enters the house. I saw this dog hook at our Vet's office and I thought it was a great way to help control a dog that greets everyone by jumping on them. With his size, it is difficult to get away. With the dog hook, he is contained in one area until he calms down. Dog hook is strong enought to hold our very large puppy and is helping us to begin to get some control at our door. Thank you Doghook!!!
