Consistent itching and scratching in dogs – a valid and common concern for most pet owners.
It's normal for dogs to experience some kind of skin irritation at one point or another.
But in certain cases, dog itchy skin problems can be severe and cause serious stress to your pet.
American Kennel Club says:
According to a Nationwide Survey of pet insurance data, for the tenth year in a row, allergic dermatitis was the top reason dogs were brought to the vet.
This condition can make your dog show signs of allergic itch, like frequent scratching, recurrent ear infections, and skin changes.
In addition to speaking with your veterinarian, the below list has five things for dog itchy skin that you can do to help relieve your pet's discomfort and stop that irritating practice.
All dogs are different, and the same goes for their skin too.
What works for one dog may not help another: for some, just a simple home remedy for itchy skin or switching to a medicated dog shampoo may suffice, while other cases may require stronger treatments.
Having a few tricks up your sleeve means you can soothe your itchy dog and help him feel comfortable again.
Why Is My Dog So Itchy?
Dog itchy skin can be caused by various things, some of which have been extensively researched in scientific studies.
These studies show that the most common cause is dry skin in dogs.
1 Seasonal Changes
It's more likely in extreme weather seasons, like the hottest months of summer and coldest months of winter, but there are other causes, too.
If you live in an area with consistently low humidity, you may have noticed that your dog's skin is very dry.
This can affect anywhere from a small area to a very large part of the dog's body.
The best way to avoid dry skin on dogs is to keep them well-hydrated.
Veterinarians warn that some of the causes of a dog's dry skin (of which dog itchy skin is one of the symptoms) may be very serious and dangerous to a pet's health.
Usually, if your dog's itchiness is severe and doesn't go away, you'll need to do tests at your local vet clinic to rule out any serious health conditions.
“Dry skin might not seem like a big deal, but it can actually be a sign of a much larger problem in your dog. Dry skin is a symptom associated with a wide range of conditions, from allergies and parasites to serious medical disorders like Cushing's disease and hypothyroidism.” – AKC.org
Of course, the first and most common, obvious cause of itching in dogs.
These small insects have become synonymous with the bites, rashes, and frustrating itch on dogs that comes along with such an encounter.
Dogs are especially susceptible as they are lower to the ground and closer to vegetation which is where fleas tend to wait in ambush.
The itching is known as flea allergy dermatitis and is usually caused by the fleas' saliva (Baker et al. 1975).
The saliva gets on and inside the dog's skin after being bit by the flea resulting in a hypersensitive reaction.
Extreme (and sometimes painful) itching usually occurs, along with a bite “bump” and some signs of dermal irritation around the wound.
The inflamed response so characteristic of flea bites can form in as little as 15 minutes from being bit to as delayed as 48 hours from being bit.
Since every dog is different in both anatomy (size, height, and weight) and physiology (how each individual responds to stress), the reaction time will vary.
But, make no mistake, it will appear sooner or later.
Surprisingly, one of the more common species of fleas that can be found on dogs comes from cats (Durden et al. 2005).
The cat flea has been shown to bite more dogs than the more logical dog flea or the more typical generalist/carnivore flea.
It is theorized that since more cats (both feral and domestic) are allowed to wander outside the home, then they have a higher potential of spreading cat fleas onto dogs who hang out in areas where they once prowled.
Today’s veterinarians have at their disposal a veritable arsenal of tools to fight and protect against fleas.
The problem with fleas is that they can reproduce at such a fast rate that it’s not just a matter of dealing with a single flea, but you must also deal with its buddies and all their eggs.
The first step would be to give the dog a quick bath to remove detritus and debris from its coat and skin.
This will make it tougher for fleas to hide.
Are there any scientifically proven solutions to fleas?
Yes. There are topical creams such as selamectin.
Studies have shown that it's one of the most effective killers of fleas (McTier et al. 2000).
It is adulticidal (will kill mature fleas), ovicidal (kills flea eggs), and larvicidal (kills flea larvae).
This step must be repeated for a few days until comb counts reveal a very low to completely nil flea count.
You'll need a long-term flea preventative.
Slow-release matrix collars allow substances and compounds to be stored within them and will slowly release these over a period of time.
These can be stored in dog flea collar treatments and have been shown to keep 95% of adult fleas and 99% of flea larvae off the dog for up to 8 months.
Finally, clean your home after a flea encounter.
Research how to eliminate fleas on the dog and around your house.
The process may be time-consuming, but it's absolutely necessary once you encounter fleas on your dog (they are sure to be in your home or backyard as well).
Here's a video guide on getting rid of fleas around the house and on your dog quickly and effectively.
The more dangerous parasite that's on every pet owner's mind.
Unlike fleas, ticks have become synonymous with disease and death in both dogs and humans.
While some may claim that it is merely Lyme hysteria, the fact remains that Lyme disease is very real and is transmitted by ticks.
If the answer to your question, “Why is my dog itching” happens to be ticks, it will likely cause a bit of panic.
Besides Lyme disease, ticks are also a vector of a host of other diseases.
Southern tick-associated rash illness (STARI), Rocky Mountain spotted fever (RMSF), ehrlichiosis, and tularemia can also be carried by ticks.
Besides the rashes and itching that are indicative of their presence, they can also bring with them fever, chills, aches, and pain.
The uninformed may say that deer ticks (known to carry Lyme disease usually) are only found in the cold deep woods or some remote back-country; however, there is scientific evidence to suggest that disease-carrying ticks can now be found in temperate zones and urban centers, and much more commonly in the US (Shaw et al. 2001).
This is a cause of considerable concern, as the range of ticks is effectively widening to include areas where they were not normally found.
Much like fleas, ticks easily find their ways onto dogs due to canine's proximity to the ground and brush, as well as dog hair providing an easy attachment point.
While it may be logical to think that the majority of ticks would be concentrated on the legs, shoulders, and muzzle of the dog, it has been observed that ticks are pretty much evenly distributed over the entire body.
However, studies have shown that flea larvae are usually found in the dog's ears, which are moist and sheltered (Kosch 1982).
They feed off the host, the dog in this case, and infection management and treatment would greatly benefit from understanding not only the life cycle of the flea but also the ecological condition in which they thrive (Dryden et al. 2004).
Treatment for ticks is a bit trickier than you would think.
There are several species of ticks, and each can carry a different disease than the other.
There is no blanket treatment when it comes to ticks on your dog, and each case must be dealt with on an individual basis.
The main step to take would be to prevent getting your dog bit by ticks in the first place.
But if a tick has already bitten your dog, are there any scientifically proven solutions to deal with a tick bite?
Fortunately, yes – there are.
In the event of a tick bite, studies have shown that a combination of imidacloprid and permethrin has a far greater effect in treating tick bites than the combination of fipronil and methoprene (Otranto et al. 2005).
While this form of treatment may exist, the best way to reduce the chances of your dog acquiring a tick-borne disease is to regularly check your dog, especially after spending time outdoors.
Use a tick-removing tool to carefully remove ticks from your dog when you find them on him.
Speak with your veterinarian to see if there are any tick-borne diseases in your area and any areas where you may be visiting and exploring with your dog.
And while you’re at it, talk to your vet about tick preventatives.
There are several products in the market that were designed to ward away ticks.

4 Allergic Environmental Dermatitis
There are more sources of it than you may think.
Dogs exposed to mites in the environment often bring about an allergic reaction that causes them to itch uncontrollably.
This condition has been dubbed canine atopic dermatitis, or CAD, and has been studied extensively over the last decade (Hill et al. 2001).
However, while exploring this condition, researchers have noticed that it is not only mites that trigger cAD but also other allergens such as house dust, pollen, mold spores, and different antigens.
If you suffer from allergies, you know how frustrating it can be to deal with.
Now imagine that same feeling, only you are not able to convey it to anyone besides scratching.
This is how dogs with canine atopic dermatitis feel.
Are there any science-based treatments for this?
Yes. Dextromethorphan, an oral medication, has been shown in studies with dogs to have significant effects on decreasing licking, chewing, and biting of themselves (Dodman et al. 2004).
Used in conjunction with some slight canine behavior modification, the use of Dextromethorphan has been observed to be an effective means of managing the effects of cAD.
Furthermore, an AVMA study has observed that Triamcinolone acetonide topical solution (TTS), a topical spray, can be used to decrease the inflammation that often comes with this form of canine dermatitis (DeBoer et al. 2002).
With few and no more than mild side effects, TTS is an effective short-term way to decrease inflammation, itching, and scratching that allergen-based dermatitis brings to the life of your pet.
5Canine Nutritional Dermatitis
What many pet owners still do not suspect.
Where allergen-based dermatitis in dogs is inflicted by the external world, nutritional dermatitis occurs when a dog's system is afflicted by something he has ingested.
Other symptoms of canine allergies can include:
Food allergies are not unique to humans.
Dogs can also display sensitivity to different types of foods, and in turn, this causes what is known as nutritional dermatitis.
There is no broad-stroke definition or list of foods to avoid, as nutritional dermatitis can be triggered by different foods, depending on the dog.
While there are labeled hypoallergenic dog food brands, none of them are actually 100% hypoallergenic for dogs.
I recommend you read this article from our DVM to understand why they aren't.
Instead, because we can't avoid feeding dogs food altogether, we need to understand what causes the allergic reaction in dogs and then block it.
We know that allergic reactions usually trigger a histamine release in dogs which causes inflammation, redness, swelling, and itching.
So, battling nutritional dermatitis in dogs is a matter of managing or preventing histamine release.
How do you manage or prevent histamine release in dogs?
One of the best ways to do this is by using conjugated linoleic acid (CLA), which has been observed in studies to significantly inhibit the effects brought upon by the release of histamine (Bloom 2008).
This is one of the most effective ways to deal with nutritional allergies and topic dermatitis in dogs.
Alternatively, the oral intake of probiotic Lactobacillus rhamnosus strain GG reduces the allergic reactions brought upon by this form of dermatitis (Marsella 2009).
This has been observed in many human trials as well.
Moreover, there are other benefits of giving probiotics to dogs, all of which are related to significant health improvements through the canine's gut flora and microbiota.
That would be your cue to get to the veterinarian immediately.
If you're dealing with itchy dog skin, there are five proven methods to help you both.
5 Remedies to Treat Your Dog's Itchy Skin
1. Try Baking Soda First
A natural itch remedy for pets is baking soda.
Baking soda is great because it's versatile and is usually something you already have on hand.
It's very cheap and an easy option if your pet is suddenly attacked with severe scratching.
People have been using baking soda to relieve itchiness for centuries.
For bug bites or concentrated areas of irritation in your dog, you can make a baking soda paste with water, which is very simple.
After that, just put a thick layer of this paste over the irritated areas on your dog's skin and let it sit for about 20 minutes.
Hang out with your pooch so he doesn't try to lick the mixture, rendering it ineffective.
After waiting, rinse it off with water. There should be no more dog itchy skin after that.
For dogs that have itchiness problems all over their bodies, prepare a slightly warm bath.
Add one cup of baking soda to the tub and mix it into the water.
Place your dog in the water and let him soak for a bit.
Make sure you pour the water over his entire body for the best benefit.
You can gently massage the coat.
2. Hydrocortisone Cream Is Often Effective
If the itching is due to a bug bite or allergic reaction, hydrocortisone (HC) cream can be a good solution to relieve your dog from itchiness.
HC should not be used on a regular basis for something like dry skin on dogs, as a tolerance can build up, and its effectiveness will be reduced.
Hydrocortisone is a very popular product for various skin inflammation and itching conditions in dogs, and it's often used as a dog ear infection treatment.
This cream can be purchased over the counter, and you can use the same kind as humans do.
However, there are certain brands of hydrocortisone cream that are designed specifically for dogs and are available for purchase.
All you have to do with the cream is to put a small amount on the affected area of your pup's skin and rub it in gently for a few seconds.
Be aware that your pooch may decide to lick off the cream and can still scratch the area.
Stay with your dog to keep him from licking off the cream for now.
When you're using any type of topical treatment for dog itchy skin, it's always a good idea to keep an eye on them and try to encourage the dog to leave the area alone to let the medicine work.
It also may be dangerous for pets to consume those products.
3. Brush Your Dog Regularly
It's also possibly the cheapest method on the list.
If your pet has dry skin and dandruff trouble, a great brushing session is in order.
Knocking out all your dog's loose fur will let your pet's skin receive better airflow, reducing scratching.
Brushing also removes dander, a common allergen and irritant.
The brushing action will spread your dog's natural oils throughout his fur, making it less likely for him to have one specific irritated area.
Many dog owners found this to be the reason for their dog's skin irritation and itchiness, and it would often go away after a good grooming session.
Brushing your Fido regularly will also stimulate his skin and increase blood flow to the area.
This can help the area clear itself out and heal.
Brushing one spot will remove any knots and tangles that have built up, that may have been causing irritation.
Finally, most dogs love being brushed, especially when they're itchy.
When brushing your dog, you always want to be gentle.
Brushing too hard can pull fur, break the hairs, or even scratch the skin, leading to further problems and itchiness.
4. Give Him an Oatmeal Bath
For dog itchy skin, one of the first things to try is oatmeal.
The reason for that is due to oatmeal being very naturally soothing on the dog's skin and coat, and it's also easy to find.
Simply prepare a slightly warm bath for your pet using oatmeal.
You can use regular oatmeal from the grocery and grind it up at home, or buy oatmeal specifically designed for bathing.
Either way, pour the oatmeal into the tub and then let your dog soak for a bit. It'll be an instant relief for your dog's itchy skin.
If you need more convenience, try using an oatmeal dog shampoo or even an effective pet conditioner for dogs.
This is also a good choice for dogs with chronic itching problems.
Using oatmeal-based products not only provides your pup with relief but it also helps you know you aren't using something they may have a reaction to.
Alternatively, you can also make your own homemade dog shampoo.
It's pretty simple, and many owners choose to do it themselves.
It saves you a little money; you also know what type of ingredients you're putting there and that they're safe for your canine.
However, other commercially made dog shampoos that are safe, organic, and natural may be a better option since they also use specific ingredients to treat itchiness and dry skin problems in dogs.
Make sure you know which type of dog shampoo your pet needs.
5. Try Antihistamines as a Last Resort
For really severe itching, over-the-counter antihistamines may be the only solution.
This is going to be something like Benadryl.
Costco's brand Kirkland sells the most popular and cost-effective antihistamines that many owners use for their dogs' and cats' allergies.
Benadryl for dogs is considered a medication that may affect your pets in different (unpredictable) ways.
Thus, it's best for you to contact your veterinarian before administering a pill or liquid of Benadryl.
Although Benadryl is generally safe for dogs, the correct dosage is crucial.
The most common dosage for something like Benadryl is .05-1 mg per pound of dog's body weight, according to PetMD.
This means you may need children's varieties of the medication since most human Benadryl tablets are stronger and bigger. You can also break a tablet in half as needed.
Only give your dog a dose of Benadryl every 8 hours.
This medication is likely to make him a bit sleepy and loopy; keep an eye on the dog to make sure he is doing fine and stays safely indoors.
