What should I look for when buying a dog shampoo?

Dog shampoos are not created equal. Some contain ingredients that may end up irritating your dog’s coat and skin. Hence, there are several factors you should consider to make sure you’re buying the best dog shampoo for the unique skin needs of your dog. Some of main things to consider include:

  • Skin condition: The first thing to consider is your dog’s skin condition. For instance, if your dog has dry or itchy skin, we recommend choosing a moisturizing shampoo without artificial fragrances and chemicals that may cause further skin irritation. Also, consider shampoos with natural ingredients like oatmeal, vitamins, and honey that can help relieve itchy skin and promote healing.
  • Fleas and Ticks: If your dog is infested by ticks and fleas, you may want to choose a shampoo that’s designed to combat these parasites and protect your dog’s skin and coat.
  • Age: It’s important that you consider the age of your dog when choosing a dog shampoo. For instance, for a puppy, opt for a shampoo that’s specially formulated for use on their delicate skins. Typically, a puppy shampoo and conditioner is uniquely designed to be gentler and tear-free, so it won’t irritate your puppy’s eyes while bathing.
  • Odor: If your dog has a strong odor, it’s best to get a deodorizing shampoo to neutralize any unpleasant odor they may have picked out there. The best smelling dog shampoo not only eliminates unpleasant dog odors but also leaves your dog with a nice smell that’s not overwhelming.
  • Shine and Tangles: If your dog has a dull and lusterless coat and skin, you should look for a shampoo with vitamins, proteins, and minerals to nourish and restore the healthy shine. Also, if your dog’s coat easily tangles or is dry, you may want to consider a dog shampoo and conditioner to moisturize and replenish natural oils, which helps in detangling stubborn tangles and frizzy locks.
  • Convenience: To make bath time hassle-free and more convenient, choose a shampoo that comes with the shampoo and conditioner combined or a waterless shampoo that allows you to clean your dog easily while on the go. The dry shampoo also comes handy especially if your dog is averse to water.


Choosing the best dog shampoo for your furry friend can ensure you keep their skin clean, fresh, and healthy at all times. All the dog shampoos are safe for use on dog skin and coat. However, you need to make sure you choose one that has the right ingredients to best meet the specific skin needs of your dog.

The 6 Best Dog Shampoos: Reviewed for 2021 FAQs (Frequently Asked Questions) 

Can I use human shampoo on a dog?

No, it’s not advisable to use human shampoo on a dog. This is because human shampoo is specially formulated for use on human skin and hair. And since human skin has a different pH than that of a dog, means that human shampoo may end up disrupting the balance of your dog’s skin. Also, the ingredients contained in human shampoo may wash away the natural moisture and oil on your dog’s skin, leaving it dry.

How often should dogs get shampooed?

How often dogs should get shampooed will depend on several factors that include dog’s coat type, skin sensitivity, skin conditions, and how fast they get smelly or dirty. If your dog has healthy and normal skin and coat, shampooing them once in a month will be enough. This is because getting them shampooed too frequently could end up washing out the natural oils that maintain their skin and coat healthy.

However, if your dog has allergies, sensitive skin, or other skin issues, they should get shampooed more often such once or twice a week. However, it’s best to consult your veterinarian to help establish a bathing schedule that will work best for your dog’s unique skin needs.

Can I use dish soap to wash my dog?

No. It’s not recommended to use dish soaps that are not approved and safety tested for use on animals. Dish soaps are especially designed for grease and oil removal so using them to bath your dog can strip the natural oils that help protect and nourish their skin. This leaves your dog’s skin and coat dry and unhealthy.
