How do I keep my dogs from chewing my planted trees and shrubs?

Fence around the shrubs/trees until they are of a size the dogs won't bother them. Are you sure it's your dogs?

Get the dogs something else to chew and plant large thorny holly bushes around the trees.
Cut up a couple of jalapenos and mix with water....spray area.
Train the dogs, make sure they get enough exercise, provide them toys to chew on and make sure they have enough to eat.
