What is Medicated Dog Shampoo?

As the term implies, these are types of hair (or coat) care products that contain substances designed specifically to treat or manage a certain health condition of the skin and coat. These can include skin inflammation, irritation, itching, dry and crusty skin, and even hot spots, among others. They are basically shampoos that you apply onto your dog’s coat, massage onto its skin, and leave it on for a couple of minutes for the active ingredient to exert its action. Like any other topical medications, there are certain things that you have to observe. For instance, you’re only supposed to use these if there really is a condition on your dog that can be effectively managed by such a shampoo. Once the problem has resolved, you can stop using the medicated shampoo altogether.

Benefits of Medicated Dog Shampoo

If you’re wondering what good is it to apply medicated shampoos on your dog, then consider the following benefits.

  • Addresses a specific problem

Conventional shampoos are basically indicated for general hair care and grooming. Medicated shampoos have a more specific function. For instance, there are shampoos that are intended for the treatment of dandruff or even seborrhea. If your dog doesn’t have either condition there is no need to use the medicated shampoo. There are also shampoos that contain broad-spectrum antiseptics which can help kill a wide variety of microorganisms. While its broad-spectrum activity connotes a more general purpose, it can still be considered as addressing a very specific problem – that of microorganism-related skin and coat conditions.

  • Provides immediate relief from certain symptoms

Since medicated shampoos are topical applications intended for superficial problems, the effects can be immediate. Unlike medications that still need to go through the dog’s stomach and absorbed through the blood to reach the target site, medicated dog shampoos provide immediate relief to your pet’s symptoms such as itching and skin redness.

  • Safer alternatives to systemic medications

The main issue with oral preparations or even injectables is that their active ingredients do not only affect the problematic site; they also affect other cells that are susceptible to such ingredients. That is why the side effects of oral and injectable medications are more profound than topical preparations. For dog shampoos, it is very rare that you get a side effect since it only works on the outer surface of the skin. Unfortunately, if the medication does get into mucus membranes such as the eyes, the potential side effects can occur.

Popular Medicated Dog Shampoo Types

To further help you gain a more refined understanding of the type of medicated shampoo that is appropriate for your pet, you’ll need to learn some of the more popular types of medicated dog shampoos.

  • Antiseborrheic

One of the clinical manifestations of seborrheic dermatitis is dandruff that is so stubborn that no ordinary shampoo can ever get rid of it. Dandruff is almost always accompanied by reddish skin and scaly patches on your dog’s skin. While it is not known what exactly causes seborrheic dermatitis, experts agree that it can be caused by certain species of fungus-like Malassezia which are typically present in the oil produced by your dog’s skin. In some cases, an abnormal response in the dog’s immune system can facilitate the proliferation of these fungal species.

Antiseborrheic shampoos help by either killing the fungus that causes flaking in the skin or dissolving the various substances that stick these flakes onto the skin. These typically contain Salicylic acid, sulfur compounds, tar-based compounds, benzoyl peroxide, and selenium sulfide, among others. Some of these agents also serve as degreasers which can help reduce the severity of seborrhea.

  • Antibacterial

The skin is home to a host of bacterial species that are not really pathogenic as long as your pet’s immune system is able to strike a balance between the normal bacterial flora and pathogenic organisms. Unfortunately, in the event that your dog’s immune system is compromised, there’s a possibility that pathogenic bacteria will overwhelm normal bacteria. Additionally, in the presence of breaks in the skin even normal bacteria can turn pathogenic as they invade the deeper structures of your dog’s skin.

Antibacterial shampoos are especially indicated in skin infections that are caused by susceptible bacteria. Chlorhexidine, benzoyl peroxide, and ethyl lactate are just some of the active ingredients of medicated dog shampoos with antibacterial properties. These do not exhibit specificity to certain bacterial species and are generally considered as antiseptics, fully capable of killing a greater number of microbial species.

  • Antifungal

Like bacteria, fungi are also present on the dog’s skin. However, they often become pathogenic in cases of immunocompromised states. Fungal skin infections are best treated with imidazole-containing medicated dog shampoos. These substances interfere with the fungus’ ability to synthesize ergosterol which is a very important component of its cell membrane. Without this molecule, fungal species will not be able to mount an effective defense against immune system cells.

  • Antipruritic

Antipruritic dog shampoos are formulated specifically to help reduce the incidence and severity of itching. Traditionally antihistamines are provided to help relieve itching. However, there are now dog shampoos that contain colloidal oatmeal that works more like a magnet to pull the allergens from the surface of the dog’s skin. These allergens are some of the most common causes of itching because of the stimulation of pro-inflammatory substances.

  • Cleansing and moisturizing

While this type of medicated dog shampoo doesn’t actually address a very specific skin condition in dogs, they are valuable in providing deep cleansing of the pores to remove dirt and debris that may clog pores. This can help prevent canine acne as well as seborrhea. Since one of the manifestations of canine skin problems is dry, scaly skin, the moisturizing effects of this type of medicated dog shampoo are also useful. You might think that ordinary dog shampoos also clean and moisturize the skin. The difference is that the cleansing properties of medicated dog shampoos are not attributed to the presence of soap. Hence, they are generally safer and gentler to your dog’s skin.

Medicated Dog Shampoo Side Effects

Medicated dog shampoos are generally safe considering that they are topical applications. However, there will always be a few side effects that can be the direct result of the mechanisms of action of the various active ingredients. Here are some side-effects you should watch out for.

  • Skin irritation and itching – these can be observed with tar- and coal-based dog shampoos and those that contain benzoyl peroxide or salicylic acid.
  • Skin dryness – this often occurs with salicylic acid- and benzoyl peroxide- containing medicated dog shampoos
  • Shedding – some formulations of medicated dog shampoos are highly concentrated that it can lead to light to moderate shedding
  • Allergic reactions – these occur if your pet is hypersensitive to any or all of the ingredients of the shampoo. Your dog may show skin redness, itching, and others.

Medicated Dog Shampoo FAQ

Q: Why should I use a medicated dog shampoo?

A:  The only time you should use medicated dog shampoo is when your veterinarian explicitly recommends that you do. While these may look like ordinary shampoos, they do contain certain ingredients that can produce localized side-effects. So why should you use a medicated shampoo for dogs?

First and foremost, it is highly specific for the management or treatment of a particular skin condition. Do take note that not all canine skin conditions have a specific medicated shampoo, so it’s best to always consult your vet.

Secondly, you get to see the effects almost instantaneously. If your pet is always scratching, you’ll notice the frequency of scratching to be somewhat reduced several minutes after shampooing.

Thirdly, the active ingredients included in the formulation of such products are all proven to be effective in their respective indications. Just make sure you understand the type of medicated dog shampoo that is ideal for the type of skin condition that your dog has.

Q: How can I properly use a medicated dog shampoo?

A:  Using a medicated shampoo on your dog is pretty straightforward with a few minor modifications to your regular dog shampooing routine. Depending on the skin condition of your dog and the type of medicated shampoo you are going to use, you can either apply it all over your dog’s coat or just on the affected area. Regardless, the procedure is essentially the same.

Wet your dog’s coat making sure that the water reaches well onto the surface of its skin. It is best to use warm water to help open up the pores of your pet’s skin.  Apply your medicated dog shampoo and massage it well onto your dog’s skin. Leave it for about 5 to 10 minutes or whatever manufacturer’s recommendation is. Thoroughly rinse your dog’s coat. Now some products may require you to leave the coat as is to allow for sufficient time for the medication to reach its intended targets before you eventually dry the coat completely.

Depending on your vet’s instructions, you may need to repeat the application several more times or give your dog its medicated shampoo every other day. It is important to adhere to your vet’s instructions.

Dog medicated shampoos are highly-specific dog care products that address certain skin conditions in dogs. They help relieve itching, dandruff, irritation, redness, and many more. This can help your pet feeling a lot more comfortable. That’s why it’s crucial that you know how to choose the best-medicated dog shampoo for your own hound.
