You have a puppy. A puppy cannot go that long in a confined space without having accidents.
Try getting one of the secure pee pad frames that hold the pee pad securely in place so he cannot play with them. Exercise pens seem to work best for puppies that are left alone for hours at a time. However, the puppy is not learning anything while it is alone. If there is no pee pad available to him all he is learning is to pee where ever he can.
Until your puppy is fully grown and fully trained you are going to have this problem. Small puppies have small bladders. Food and water goes through them quickly. If he has to be on his own this long you have got to provide some sort of potty for him. Crate training does not work for a puppy that is left there with no supervision. If they have to go they have to go and no crate is going to stop that. |
