Could My Dog Be Allergic to Something in My House?


Your house should be a safe place for your dog. But your house can be hiding numerous allergens that your dog can become allergic to.

Could my dog be allergic to something in my house? There are many dog allergens found in homes. These include dust, dust mites, mold, cleaning products, air fresheners, laundry products, rubber toys, and even other pets. Changing or removing the source is critical to the health of your dog.

Our dog, a border terrier, called Alfie, has had many allergies and we have gone to great lengths to eradicate the sources of his allergies.

It takes a lot of time and patience to pinpoint what your dog is allergic to, but it takes a lot longer if you don’t know how to tackle the process in the best way. I’ll give you the best tips below to get you there in record time.

What Are The Main Dog Allergens Found In Your House?

  • Dust: Dust can be as much as an irritant to your dog as it can be for you. Dust can so easily enter the eyes and throat of your dog causing allergies in the eyes or the respiratory system. Consider investigating this further if your dog suffers from watery or irritated eyes, or frequent periods of sneezing.
  • Dust Mites: Dust mite allergy in dogs shows up as skin irritations. Atopic dermatitis is a condition that gives rise to a breakdown in the skins’ protective barrier. Your dog will exhibit the behavior of frequent scratching. The face, abdomen, armpits and between the ‘fingers’ of the paws are all common areas to notice this scratching behavior.
  • Mold: Intense and frequent scratching or gnawing at various body parts can be a sign of mold allergy. If skin sores appear or hair loss, then consider mold allergy as being one possible source.
  • Household Cleaning Products: If your dog is allergic to cleaning products in your home then this can be one of the most difficult allergens to spot. Allergies to cleaning products can show up as coughing, sneezing or skin irritations. Changing to more natural cleaning products can help identify these products as being the source.
  • Air Fresheners: Whether you use plug-in air fresheners or the spray varieties, both types can cause allergic reactions in dogs. Itchy skin, eye irritation or lumps appearing on your dog’s body can point to this allergy.
  • Laundry Powders and Conditioners: If your dog constantly licks the same parts of its body, or if the skin has hives, then these are possible symptoms of these types of allergy.
  • Rubber Toys: Latex is a fairly common allergy for dogs. Latex is one of the main ingredients in rubber toys. The symptoms are very similar to many other dog allergies, so the easiest way to test is to remove all rubber toys and see if the symptoms ease off and then disappear.
  • Other Pets: One of the less obvious allergies for dogs is being allergic to another pet in your home. Your dog’s eyes can possibly a clue to this allergy, especially if they are red, watery or appear puffed-up. Sneezing is another clue to this allergy. It’s rather like hayfever for humans, so the symptoms are very similar.

In addition to the above, there are various other possible allergens that may or may not be present in your own home.

Just like with humans, dogs can be allergic to cigarette smoke. Typically, your dog’s eyes will be affected first and could be in the form of red or watery eyes. Sneezing could also be associated with this allergy.

Just like with humans, dogs can be allergic to cigarette smoke.


If you believe that cigarette smoke is causing your dog any discomfort then do the right thing, and smoke somewhere away from your dog, and preferably outside.

Pollen isn’t exactly a household allergy, but it is once it gets inside your home. Flowers brought into the house, or windows left open in summer can be certain to allow pollen into your house. Air purifiers work wonders in helping dogs with pollen allergies.

Mold isn’t pleasant or safe in any home. If you have a room where mold is a problem, then take a look in your hardware store for mold treatments. Many of these solutions are very easy to use and could save you and your dog from ill-health.

Ways to Reduce or Eliminate Dog Allergens in Your House

There are certainly some simple and affordable ways to reduce your dog’s allergy issues associated with your home.

Airborne Dog Allergens:

For airborne allergens resulting from any of the following, your best and easiest solution would be to purchase an air purifier. Amazon has an excellent range for every budget right here: Air Purifiers

  • Cigarette Smoke
  • Mold
  • Dust
  • Pet Dander (microscopic particles released from animals’ skin)

A positive side effect of having an air purifier is that it can also help similar allergies for the humans in the family also.

Dog Allergies Associated to Household Cleaning Products:

Most household cleaning products were never formulated with dogs in mind.

Your dog is going to be walking on the floors you have cleaned, licking surfaces that you may have polished and eating from his dish where you may have been spraying cleaning solutions earlier in the day.

While we all tend to believe that commercial cleaning products are better than homemade alternatives, you may like to reconsider that false belief.

Baking soda, vinegar, and lemon juice can work miracles around your home, and your dog will certainly thank you for your efforts.

Keep some of your old bottles from your commercially made cleaning solutions and then make your own cleaning products to fill them up with. The video below gives some great details for doing this.

Dog Allergies Associated With Dog’s Toys

There are a few sources of dog allergy that you can simply replace with something that is safer.

Dog’s that are allergic to Latex (rubber) are highly likely to have been fine with rubber toys for a number of years. Over-exposure to rubber over a course of time can begin to trigger allergic reactions that had never been present before.

Fortunately, this is an easy one to fix by simply disposing of the rubber toys and replacing them with other dog-safe materials.

Almost all dental stick chews are also allergy free. Nylabone and antlers are also safe bets.

Replacing dog toys is one of the easiest dog allergy threats to tackle yourself with little effort or expense.


We all like to feel safe and happy in our homes, and we should all aim to ensure that our dogs also have those same comforts.

Dogs can’t tell us when they feel unhappy or unwell, but their actions speak louder than words.

All dogs scratch, but when the scratching becomes too commonplace then it’s time to think about dog allergies.

Your dog spends a lot of time with you, so their allergy is likely to be something that is around you all the time. Think of the most common allergy triggers first as it’s highly likely that one of those is the issue.

I haven’t covered dog food allergies in this post as I have saved that for another post, but aside from dog food, always be mindful of the allergens within your four walls.

One thing to take away from this post is that dogs can develop allergies to things that never caused any issues for them in the past. Exposure over time can increase the chances of a dog allergy taking hold.

Likewise, once a dog has become allergic to something, it can increase their chances of becoming allergic to other allergens. The sooner you can combat your dog’s allergy, the better.

Regarding household cleaning products, do take a look at the video in this post. Making your own cleaning solutions is not only healthier for your dog, but it’s healthier for you and your kids too. Not to mention saving you money at the same time.

As always, speak to your vet if you have any concerns about your dog’s health.
