Age Appropriate Training
To be successful, one must understand the limits that a puppy has. A Yorkie puppy can only hold their needs for a certain amount of time. To not allow your puppy to relieve themselves within this time frame, is setting the dog up to fail.
A 2 month old Yorkie puppy can hold its needs for 2 hours at the most. A 3 month old Yorkie puppy can hold its needs for 3 hours at the most.
This continues on until the dog is an adult, at which time the Yorkie can only hold on for a maximum of 8 hours.
