What Material Can Dogs Not Smell Through?

Dogs cannot smell through airtight, vacuum sealed containers, despite the fact that they often have quite amazing senses of smell. Puppies have the ability to smell inside of, outside of, inside of, and even under objects.

While many things can be odor-resistant, some items can be a little harder to protect your dog from smelling. Plastic containers, which are used to store food, are the biggest culprit. Plastic can absorb odors and make it impossible for your dog to process other scents. Bleach and other chemicals can also overwhelm your dog’s sense of smell, making the materials in these containers unhygienic and potentially dangerous.

Mylar bags

To avoid giving your dog a rotten smell, you should buy a vacuum sealer to seal the bags. However, finding a vacuum sealer for mylar bags can be difficult. Luckily, the internet is one of the best places to look for these products. Listed below are some of the most helpful vacuum sealers for mylar bags.

Mylar bags have a shelf life of about five years. Unlike paper bags, these can be reused over again. When buying mylar bags, be sure to choose the best quality material. A good-quality bag will have no scent, even when used for storing nuts and dried fruits. You’ll have to ensure that the material is snappable since dry fruit can be chewed through.

Vacuum-sealed containers

When storing food in a vacuum-sealed container, it is vital to use a scent-proof bag or jar. These materials protect your food and help keep the flavor within. Unlike humans, dogs cannot smell through a vacuum-sealed container or plastic bag. However, scent-proof bags are not entirely foolproof.

While the human nose cannot detect vacuum-sealed items, trained drug dogs can. The police officer’s statement that vacuum-sealed containers are not dog-proof may be intentional misinformation. Studies published in 2019 showed that dogs can detect cancer cells from blood cells in plastic tubes. This shows that dogs’ sense of smell is far superior to humans.

Mason jars

It would be best if you never used Mason jars as storage containers for your dog. Mason jars are not vacuum-sealed, so odors and air can escape. In addition, dogs can sniff through walls, which is why police departments use K9 units for drug detection, search and rescue, and people-finding. But if you want to protect your dog’s health, you can buy vacuum-sealed bags that block your dog’s nose entirely.

Another alternative to Mason jars is Weck jars. These German-made containers have rubber sealing rings and are made for canning. However, this method is not approved by the USDA. Weck jars come in different sizes, and you can buy a lid. The lids can be removed if you use them in the microwave. If you choose a lid that is not airtight, you should always wash your hands thoroughly before touching the food inside.

Ziploc bags

Most people think dogs can’t smell through Ziploc bags, but the opposite is true. They can detect smells through plastic, but most dogs can’t detect these scents. It’s not just plastic that doesn’t let dogs smell. Even coffee can smell through a Ziploc bag, and dogs trained to sniff for drugs can detect them. Ziploc bags do not completely smell proof, and untrained dogs won’t even bat an eye.

Since dogs have an excellent sense of smell, they can detect drugs. Usually, they will detect drugs and marijuana, but they can also detect anything with a minute smell. This is why it’s essential to use Ziploc bags that are watertight and airtight. Besides, you can also train your dog to smell through ziplock bags and other plastic containers. In addition to drug detection, you can use Ziplock bags to detect explosives and other substances.


Dogs can smell through various types of material. Some of these materials are made of multiple layers and contain different smells. Citrus fruits are one such example. Unfortunately, citrus essential oils are much stronger than the fruits themselves. This makes them more offensive to animals. Fortunately, there are other materials that dogs cannot smell through. Here are some of them:

Air fresheners

A dog’s nose is susceptible. It can detect one molecule out of every trillion. However, that doesn’t mean dogs can’t smell through air fresheners. Some research suggests that dogs and cats can’t smell through air fresheners. The adverse effects of air fresheners can be felt immediately, while in others, they can take a few days to appear. Dogs may experience lethargy or even vomiting.

Air fresheners aren’t the only solution. There are many ways to diffuse the scent, including using plug-in units. Plug-in units use fragrance beads, which disperse the scent more evenly than oil or water. In addition, plug-in units can be easily plugged into any wall or ceiling, allowing them to last for hours. Other types use water, which is ineffective at getting through the walls and floors.


A dog’s nose is more powerful than a human’s, which means it’s sensitive to environmental scents. Dogs also use scent to communicate; some of their behavior may have something to do with this sense. For example, if your dog has an itchy paw, you may find that it likes rolling in the grass to relieve itself of the itchy feeling.

The grass is a ubiquitous snack for dogs, which is thought to be a relic of their ancestors’ hunts. In the wild, wolves often ingest plant material into their prey’s stomach, and dogs can smell it through the grass. Unfortunately, the material is also complex for dogs to digest, so grass may not be a good option for dogs trying to eat a balanced diet.


Dust is a common allergen. It is not a health risk to your dog but can cause allergic reactions. House dust contains many different allergens, including fungi. The most common cause of an allergy to house dust is dust mites. These creatures live in homes with high humidity levels. The humidity level should be about 75 percent or higher. The dust mites will die if the humidity level drops below 50 percent. In dry climates, these allergens are not a problem.
