Which medicated shampoo does your dog need?

This is often the big question. Unless your dog’s skin/coat problem has been diagnosed, you may not know what the problem is. In that case, you could buy various medicated shampoos and then be disappointed when they don’t work. Plus, your dog continues to suffer. The problem isn’t with the shampoo. It’s because you’re not using the right product. That’s why it’s often a good idea to see your veterinarian and get a real diagnosis.

Once you have a diagnosis, your veterinarian will probably tell you what kind of shampoo your dog needs. She may even offer to sell you a product. This is when it can be in your best interest to buy the product online instead from a site like The exact same products are commonly sold online at a much lower price than you can buy them from your vet.

In some cases you may not need a veterinarian to diagnose your dog’s skin/coat problem. If your dog has a hot spot; if his skin is irritated from flea bites; if he has been scratching his skin because it’s very dry and itchy you can probably choose a good medicated shampoo without a trip to the vet for a diagnosis – unless there is also an infection involved.

Medicated shampoos may contain sulfur, coal tar, chlorhexidine, salicylic acid, benzoyle peroxide, ketoconazole, or other medicated ingredients.

Your dog’s skin is the largest organ in his body. Any illness that affects him usually affects his skin, too. So, it is important to pay attention to your dog’s skin and coat not just for themselves but as indicators of his overall health. If your dog is having skin and coat problems, consider other things that could be affecting him such as his diet, environment, genetics, stress, exercise (too much or too little), illness, and so on. Medicated shampoos can help your dog but you also need to look at the big picture of his life.
