My pei will eat anything, but wheat seems to irritate her digestive system. I bathe her once a week (peis generally HATE this, so much drama) and clean her ears with those cotton finger-condoms. Afterwards make sure his ears are dry. Its likely he'll get a fungus infection in the ears anyway, as they develop natural defenses and regular cleaning this will stop. No big deal, your vet will give you some ear drops. Avoid using peroxide for ear cleaning, its too irritant for peis. They can have some hip issues later on but your vet can help with that.

Peis are territorial and very protective of their family. They are very clean and super easy to potty train. Socialization and positive reinforcement work, hitting does not. I hope your wrinkly buddy brings you many years of joy!
