For dogs, citrus scents are the enemy. Citrus scents like lemon, lime, oranges, and grapefruit–especially in high concentrations often found in household cleaners or essential oils–can cause irritation to your pup's respiratory tract, so keep any fresh citrus fruits out of your dog's reach. You know–just in case.
Vinegar is another household item that dogs stay away from due to its strong smell. You can use vinegar straight from the bottle to sprinkle or spray.
You can use vinegar to keep dogs away from your lawn by spraying it around the perimeter of the area you want to be canine-free. Dogs don't like the strong smell of vinegar and thus will be deterred by it.
Diseases. Improper air flow, affecting olfactory skills, could be caused by diseases such as nasal cavity tumors, local injuries, or specific infections such as canine distemper or parainfluenza.
The methodology of observing the dogs freely exploring the experimental area allowed us to determine the smells that were the most attractive to them (food, beaver clothing). Our study shows that dogs interacted more frequently with the scents of blueberries, blackberries, mint, rose, lavender, and linalol.
Many (but not all) dogs hate the smell of citrus, so using citrus smells like citronella, lemongrass, lemon, and even bergamot can repel some dogs from an area. You can use these smells in scented candles or sprays to see if it keeps your dog away from an area where you don't want them peeing.
Sound or Noise Phobias
Many canines suffer from the fear of loud sounds such as thunderstorms and firecrackers. Scientist claim that sound phobias pass through genetics, for example herding breeds are more sensitive to sound.
Cynophobia is an extreme fear of dogs. The name of this phobia comes from “cyno,” the Greek word for dog. Children and adults with this disorder go out of their way to avoid dogs.
Most typically, we find dogs that are afraid of loud noises, such as thunderstorms and fireworks, but also they can become fearful of children, men, riding in cars, going down stairs and such, or esoteric things, such as butterflies or flickering shadows.
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. Another popular – although sometimes controversial – option is cayenne pepper or strong chili powder.
Since dogs have a very good sense of smell, the lavender oil should always be diluted, otherwise, it is too potent for any dog to enjoy. Although most dogs seem indifferent to the aromatic smell of lavender, some dogs appear to actually like it a lot even though it is quite rare.
In an experiment, dogs were surprisingly accurate in detecting sweat and breath samples from people who were stressed. It's long been widely believed that dogs can detect extreme emotions by smell.
Eucalyptus oil is used in aromatherapy to treat breathing problems (4). The smell of eucalyptus can be very overwhelming for dogs in both positive and negative ways. But all these benefits are for humans.
Key takeaway. Dogs sniff people's crotches because of the sweat glands, also known as apocrine glands, that are located there. Sniffing these glands gives a dog information about a person such as their age, sex, mood, and mating probability.
Introduction. Dogs can smell many things. Their sense of smell is so finely tuned that they can smell termites underground, rats hiding in tunnels, and snakes slithering in the bushes.
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.
Not only will a vinegar and water solution eliminate urine odor if your dog has already peed on the rug, but it will also deter them from urinating on the same carpet again. The acidic smell of vinegar is known to repel dogs from peeing on area rugs as they do not like the smell of vinegar.
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.
