Is my puppy's diarrhea and eye discharge from new puppy stress?
Stress can certainly cause diarrhea in dogs. If Dex is eating and drinking normally, we will often recommend a bland easily digested diet consisting of ½ cooked white rice and ½ cooked white meat chicken (boiled without any skin or bones). If he does well with a bland diet and his diarrhea resolves, then you can slowly transition back to his normal diet over a few days. Diarrhea that continues for more than a few days, or is associated with blood in the stool, vomiting, lethargy or a poor appetite is a reason for a visit to your veterinarian. There are anti-diarrheal medications that your veterinarian can prescribe and they may also recommend a probiotic to help resolve the diarrhea.
I have attached a couple of links below with more information for you.

If the green discharge in his eyes does not resolve in a couple of days, worsens or he starts squinting, I would certainly have your veterinarian examine his eyes to make sure he doesn't need any eye medication.
Good luck! I hope that was helpful and that he feels better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
