I don't personally know of any studies on perfume and horses, but scent is definitely an important factor with them. An anecdotal illustration for you: my stallion, when he was a yearling, was handled a lot by my husband when I was pregnant. After my baby was born, he was upset by the changed smell on my husband, and would act out when handled. The solution was for my husband, who was a smoker, to smoke heavily before getting to the barn so as to mask the new scent.

Stallions in particular appear to be very scent-sensitive, as I jave seen in several other less easily described instances. For this reason, my stallions do not share halters with other horses, especially mares. Some women feel that their changed scent while on their menstrual cycle may cause difficulties with the stallions they handle. Many stallion owners/riders/trainers will use Vicks to block scent so that the stallion is not distracted by the scent of mares.

Mares also use scent to help recognize their own foals. A useful method (which I have not had occasion to try) to get a mare to accept an orphaned foal is to bring back the scent of amniotic fluid and/or placenta. Another that I have heard of is to block scent until the mare accepts the foal. I know there is a product designed to change scent on cattle for this purpose.

I think a study on perfume/scent and equine recognition of people would be quite interesting. It may help understand why horses sometimes immediately take to one person while evading another.

thank lydia for your answer and for sharing your experience with me. its will known that formones are one of the basic ways of contact in animals . but we still need this kind of study in horses and birds .

Applied the spray or shampoo( perfume) directly on skin can cause skin reaction in most animal, some time nausea or even airway irritation and some types of perfume have calming effect on pets.

some people have reported death cases in horses and donkeys after smiling direct perfumes

there were a previous reports and data from owners refers to significant changes and cases of abortion specially in pregnant mare in last stage of pregnancy

clinical signs were: abortion, nervous signs, nausea, vomiting, death to mare and baby foal in some cases specifically with direct smiling or contact to perfumes, gasoline, cars oils and chemical agents.

I think these perfumes may be cause a kinds of anaphylactic shock or stress to the animal which stimulate a series of changes leading to secretion of dexamethasone or prosatglandin F2 alpha which leads to abortion at the end or death in sever cases.

as any way, I agree that these project needs to more studies for understand whats really happened.

my best wishes.

it may has positive or negative effects

Conducting research on how perfume affects Rover is tricky, for the simple fact that dogs can't easily convey their emotions upon encountering a certain scent, explains

Dogs and cats can also have allergic skin reactions to perfumed shampoos, sprays, and lotions. These can manifest as redness of the skin, itching or biting at the affected area. Cats are especially sensitive to the respiratory effects of inhaling perfumes.

I think it depends on animals types , some animals are more sensitivity than other animals , like dogs , cats and horses.

Its has been shown to have calming effect on pets.

its depending on types of perfumed and the additive in its most perfumed are alcoholic or watery also some mixed with other compounded all these may effect on specific animals type and can lead to hypersensitivity or allergy also some perfumed act as pheromones lead to attract some species of insect or parasite to animals

It depends on the species of the animal. Some of animals are more sensitive to the perfumes like pets, horses and some kinds of parrot and love birds.

Horses have a much better sense of smell than we humans. ... They aren't as good at scent recognition as a dog, but they are able to identify predators and other horses by their smell. The horse's long head means that it has quite a large nasal cavity.

The main sources of animal musk are the secretions of civet cats, beavers, and musk deer. Perfumers also use a natural animal product called ambergris derived from sperm whales and pygmy sperm whales that we will discuss here, as well.it became clear that there are different opinions on whether perfume should be worn around horses. It was mentioned that it could be dangerous if worn around some stallions although there was no evidence that I could find to substantiate that suggestion. It was also mentioned that perfume can be attractive to bugs and biting insects. Horses, like people, have allergic reactions. Perfume can be an offending allergen not only to you and others, but to your horse. I always tried to have as few foreign scents at the barn as possible. I never wore perfume or hair spray; however, I did wear deodorant!

Depend on the species of the animals

Ithink it depends on animals types ,

Depend on the animals species

Animals such as dogs and cats are allergic to special perfumes that the breeder has sprayed at home

Experts say that letting lions, tigers, and leopards smell new scents keeps them mentally and physically active. Before discarding your old perfume bottle, consider donating it to a zoo. Certain animals, including lions, tigers, and leopards, are attracted to unique perfume scents.
