Welcome and Congrats! Cant wait to see some pics
What kind of food is best for puppies?
I feed mine Innova its a high quality food and Lola seems to like it
What kind of treats are good for the puppy? and for training?
Lola like her Bully stick which you can get from yt member "AMD" her website is
www.westbrookdog.com Lola also like her himalayan chew (it made from yak and cow milk, basically its cheese) and it last for a long time. Get for big chewers
What shampoo is good?
I really like using BioGroom, if you contact the company they will send you samples to try
Do you think a puppy litter box is good for the home?
I use the pee pads for Lola and they work well for her. If you decide on the litter system, be careful some dog like to eat the pellets and can choke.
Hope this help...good luck with the new pup and remember we're here for you
