Table salt, sea salt, Epsom salts or good old-fashioned ocean water can relieve itchy dog skin. However, they can also lead to dry skin so you will have to find the right balance to treat your dog's skin. More good news: salt baths have been reported to kill fleas by dehydrating the pesky critters. Although they may not completely resolve your dog's flea problem, a salt bath can be part of a treatment regime to combat fleas on your dog.
If you have a water-loving dog, a bath with salt water is really just a bath--no difference to your dog. Unless, of course, over bathing in salt water dries out his skin and makes him itchy, which is just what you are trying to avoid. Used carefully, salt water bathing can relieve itchy skin from allergies and even counteract parasites such as fleas, which will make your dog happy, happy. And if your pet is a good swimmer, a swim in the ocean is just as good as a swim in the lake, it’s just bigger and with more great stuff to explore!
Salt water can be used to treat itchy, allergic skin, on your dog, or skin affected by parasites such as fleas. You can make salt water at home, or head out to the beach if you live near the ocean, to get your dog his saltwater fix. Remember that salt water can dry skin out too, so find the right balance to relieve itchiness. Cool water may be more effective for relieving inflammation. Do not rinse all that good salt off afterward, as that is what will discourage fleas and relieve inflammation. Be careful, however, that your dog does not ingest salt water, especially Epsom salts, which can give him tummy troubles or dehydrate your pet.
