At the very least, it’s recommended to bathe your dog at least once every three months. You can wash your dog as often as every other week, with a gentle shampoo, it could be even more frequent. When in doubt, use your judgment — if your dog starts to smell, it’s probably time for a bath. Keep in mind that your dog needs their natural oils produced by the skin to promote hair growth. Plus over bathing can cause irritation and dryness. So just don’t over do it!
