These natural homemade dog shampoo bars feature neem oil, which is especially helpful at repelling fleas and treating a variety of skin complaints.
Since neem has a fairly strong aroma, I also included some lavender essential oil to help mellow the scent and to add a calming note to bath times.
After washing your dog with a shampoo bar, follow with a diluted apple cider vinegar rinse (1 part vinegar to 1 to 2 parts water) to help remove any soap residue and to leave your dog’s coat clean and shiny. Rinse well.
Lavender infused vinegar is perfect for rinsing dogs with! You can find directions for making it in my Five Uses for Lavender Vinegar blog post.
