We have an 8 year old English Bulldog who has the usual bulldog issues with his hips. And he is now 73 pounds. He spends most of the day in two rooms upstairs, although he has the freedom to go anywhere in the house he wants to go. At this stage in his life, he does not go up and down the stairs often, usually only when he needs to go outside-twice a day. We gave him Detoxapet a few days, and the difference was remarkable! He not only went up and down the stairs several times a day, he RAN up and down the stairs. That was after only a few days on Detoxapet. We were sure there must have been another reason for the change, but we made no other changes to his daily routine: food, exercise, water, supplements. Nothing. He was not taking steroids from the vet. It had to be the Detoxapet. This is our sixth bulldog, and we will never be without Detoxapet from now on.
