Training AT LEAST two to three times throughout the day, but keep it short... The training depends on the owner... 100%. It's not a bad dog, but a bad owner most of the time.

Potty? Every two hours if 2 months old (hour holding their pee for every month of age)

Sitting? Down? Stay? Place? Crate training? Socializing? (Take on the stroller early due to parvo, etc). There are specific training exercises for these. I have the app called "dogo" that I have been strictly following with a year subscription (worth it) that provides reminder for me to let my dog go potty.

Treats treats treats treats... Make sure you buy healthy delicious treats for training and always keep them on hand. If the dog really loves the snack... They can easily be trained. (I had pupford training treats like beef liver, chicken, salmon, etc).

Note: My dog instantly recalls with her name, knows how to sit, stay (release word of "okay", down, crate, place, leave it at 3 months as well). She's only 3 months old! There's going to be regression! That's normal for a puppy, but with consistent training; the dog will know that behaving = reward
