You should start it at the age of 5 weeks for Potty Training Your Puppy
5 Weeks of age – a Pup will usually potty after walking, eating, drinking and playing. Thus, go potty many times a day at this age. During this time of early growth, you are purposely measuring the time between breaks.
While decreasing the golden-opportunity for the pup at a regular rate. You must see the deed(s) done or crate (contain) the pup in a small safe potty area.
Remember, it is important to use a calm, soft potty word while the deed is in process. Do not distract pup from finishing the deed. Follow through with gentle praise and take pup inside for a carefully monitored visit.
1st break-immediately after waking (do not take the time to get dressed, it is too late!) and only after seeing the deeds done (give at least 5 minutes) Allow pup to stay with you for the short time before you leave for work.
2nd- If longer than 30 minutes set timer on stove and take pup outside to exact spot of potty area (this should retain a scent pad of a small stain of urine or feces from before). Continue breaks-every 30 minutes, unless in a crate or contained in a safe potty area.
Continue until 3 failures at the 30-minute mark. Then set timer for 45 minutes. Continue breaks-every 45 minutes until 3 failures to make a potty at the 45-minute mark. Then set timer for 1 hour.
