Most dogs are averse to peppery scents, like black pepper and cayenne pepper, which is why some people use them as canine deterrents.
The popular seasoning worldwide might make your food taste good, but it doesn't smell very good to your dog. The spicy aroma of black and cayenne pepper can irritate your dog's nose and throat. It can also cause them to sneeze and wheeze if inhaling some fine peppery particles.
Sneezing: Because black pepper is spicy, it can irritate your dog's respiratory system, which may cause sneezing as your dog tries to rid the irritant from their airway. Sneezing isn't usually serious and should be relieved in a minute or two.
Black pepper is another seasoning where moderation is key. Although a small amount of black pepper is generally considered to be safe for dogs, large quantities of black pepper can cause stomach upset in dogs.
Pungent herbs like rosemary, mint, and basil are enough to make a dog crazy. Despite their distaste, these scent aversions can come in handy when reinforcing good behavior–especially when you want to keep your dig-happy dog out of your garden.
Unwanted Scents
Dogs tend to avoid scents that make them uncomfortable. For example, most dogs hate the smell of ammonia-based cleaning solvents, vinegar, and chili peppers. If your house smells strongly of scents that are unpleasant to your dog, the dog may feel uneasy and act aggressively.
When a dog is exposed to cayenne pepper, the animal's reaction can cause the spice to spread, leading to more irritation, which could last for days or weeks, said Carlo Siracusa, associate professor of clinical behavior medicine at the University of Pennsylvania School of Veterinary Medicine.
Dogs can eat peppers cooked or raw, as long as you don't add any seasoning or cook them alongside ingredients like onion or garlic, which are toxic for dogs.
Hot Spices & Citronella oil
Hot spices like cayenne pepper are good options for deterring chewing.
The discomfort that capsaicin causes to your dog can lead to a variety of different symptoms. When dogs feel this type of heat, they may cough or sneeze, drool, or foam at the mouth. The heat may also cause your dog to paw at their face and pant. Some cases will cause the eyes to water.
Not only can inhaling black pepper lead to respiratory problems like lung irritation and asthma, it can even cause death, especially in children. So always have black pepper in your food and drink, where it is meant to HELP your breathing, not take it away.
If you can immediately flush the affected areas (eyes, nose, mouth) and relieve the discomfort, you may not have to take your dog right to the vet. However, if after a few minutes of flushing, your dog does not seem to be getting any better, you may want to take a trip to the emergency vet office.
Vinegar. Just like citrus, dogs cannot stand the smell of vinegar. It seems that a dog's heightened sense of smell is not keen on acidic smells, vinegar being another very acidic substance. It is worth noting that dogs are more repelled by the smell of vinegar than they are by lemons and oranges.
Something that is generally very effective is vinegar – dogs seem to hate the pungent, acrid smell of vinegar, and its application in a few strategic locations may do the job.
Hot peppers like poblano peppers, jalapenos, and chili peppers are a big no-no for your dog. That burning sensation that some people love about eating hot peppers isn't something that translates well to your dog. They will hate it.
Salt can be toxic to dogs, so it's never a good idea to share any salted foods with your dog. Pepper can also cause stomach upset in dogs because it irritates their digestive system. Ultimately, there's no good reason to share salt and pepper with your dog.
Don't think that by hiding pot in coffee grounds, or masking the scent with Bounce fabric softener or vanilla extract, you're gonna be okay. Police dogs are trained to cut through these scents. Petroleum and cayenne pepper don't work either—a dog may jerk back after smelling it, but humans will recognize the reaction.
To stop dogs from chewing and licking furniture, you can try applying some homemade bitter apple spray to the items. It is a great non-toxic deterrent that will prevent your dog from further chewing or licking. Of course, it is unpleasant for them, but it's also harmless.
Now a study has found that dogs can do something just as remarkable: sniff out stress in people. The dogs were able to smell changes in human breath and sweat, and — with high accuracy — identify chemical odors people emit when feeling stressed.
In recent times, research has shown that: Dogs can recognize emotions in people's facial expressions. They're able to distinguish emotional facial expressions from neutral expressions, and they can tell happy faces from angry ones - just from photos of faces. Dogs can sniff out human emotions by smell alone.
If a dog is stressed or frightened, a large amount the the anal gland secretions can be expressed all at once, leaving a very strong fishy or musky odor behind. Whenever a dog sniffs another dog's rear end, it is this smell they are investigation.
As there is limited scientific data related to canine smell preferences, the purpose of this study was to verify dogs' reactions to selected scents, which can also be appealing to humans. Our study shows that dogs were more likely to interact with the scents of blueberry, blackberry, mint, rose, lavender, and linalol.
