I am sure that there are more YT members with experiences.. but I thought I would share mine

And i hope others would share theirs!
In terms of potty training...
I don't know how big your pup is.... but it might be worth it to get a playpen. I had a shower curtain underneath of playpen for any leak!! Then I put one peepad on one side. I left her in the playpen most of the time right next to me. I held her many times of the day for short time each. WHen she peed or pooped, I praised her. If she tried to pee elsewhere, I lift her up and put her on the peepad. WHen I changed to the new pad, I tried to rub the new peepad to old peepad, so there is some smell with new pad. I also took her to outside in warm days and if she pees or poops, I praised her. I think they can smell other dogs' poop and pee, they might have easier time to do it outside. But Haruka had hard time going outside for pee and poop in the beginning and waited for going home to do her business.. But then I decided to take her out very often for long time, she started going outside as well.
I used to dogsit two dogs often. My challenge was that I had to take them out 8 a.m, 6 p.m. and 11 p.m. everyday. It didn't matter snow days or rain days.. or stormy days. I just couldn't imagine doing that every day. SO I made sure that Haruka goes to peepad at home as well. It is easy... I just need to pick up the poop with toilet paper and flash! I changed the peepad every other day or so... because she goes outside sometimes too.. Now she doesn't use the playpen unless I have to leave her when I go to work... and she has the peepad outside in two separate rooms... It works so perfectly for me
In terms of biting... I think it is important to provide a toy that is helpful for your pup's teething. When she used to bite me, I would give her the hoof or kong. And when she decided to buy them instead, I pad her and said "good girl." When she bit me, I used to tell her "No" and made her to sit down.... She is really a good behaved girl now

It is not their fault that they are teething.. so we just need to make sure to give them something substitute to bite

hoof was great for me even it stinks !
