Morkies are prone to allergies, so bathing them too frequently is not advisable. However, bathing your dog once every one to two months is perfectly acceptable, as long as you follow this golden rule: if it smells bad, its time to bathe it. You should always wipe down your dog before bathing, and after you’ve done so, you can apply some of your favorite natural remedies, such as coconut oil, apple cider vinegar, tea tree oil, etc.
