blog 1 - Potty training your puppy
You should know that a puppy cannot hold it for more than 2 hours per month. Thus, a 3-month-old puppy cannot hold it for more than 6 hours. It is therefore normal for the dog to wake you up during the night to go out to do its business.
If the dog makes a mess in the house, do not punish him. Punishment will only encourage the dog to hide to relieve himself next time.
The key to success is to always supervise the puppy and take him out as often as possible.
