Is it okay if my puppy only eats wet dog food and not dry kibble?

Most commercially available canned foods are still balanced diets. As long as Zoey is eating a food formulated for growing puppies, she should still be meeting all of her nutritional needs. However, being a small breed dog, she is naturally more prone to developing dental issues as she ages. Dry food is a bit more abrasive to the teeth, which will help to decrease tartar formation. You can try mixing a small amount of dry food with her wet food to try to tempt her to eat it. Otherwise, be sure to brush her teeth daily to maintain oral health. Be sure that you are feeding a high quality brand of food (Science Diet, Purina ProPlan, and Royal Canin are some of my favorites), and keep Zoey on puppy food until she is 1 year old. Anytime you change flavors or brands of food, mix the old and new foods together over 5-7 days for a slower transition to decrease the incidence of vomiting and diarrhea. Wet food should be just fine provided that you stay on top of brushing her teeth. :-) I hope that all goes well!
