At 4 1/2 months I don't believe your pup is fully trained. I think you need to keep up the constant supervision, frequent trips outdoors, a firm "NO" when you catch him going indoors, and crate/exercise pen use when you can't watch him constantly.
Cesar's books are really helpful. I read "how to raise the perfect dog" and found it really helped me understand the stages of life and learning of dogs. I may not implement every training method, but having a firm knowledge of the pyschology of dogs is a great help.
Good luck! Don't give up. Diligence and constant attention at this stage is required. |
