Dolce & Gabbana introduces a $100 dog perfume line, modeled after the designer's own poodle.

• The alcohol-free fragrance mist for dogs created by the Italian fashion house, priced at £83 ($105) on its U.K. website, was inspired by Fefé, the pet dog of brand-owner Domenico Dolce.
• According to Dolce and Gabbana, the scent has a blend of "fresh and delicate notes of Ylang Ylang, Musk, and Sandalwood" and is packaged in a green lacquered glass bottle with a 24-carat gold-plated paw on it.
• Some animal welfare organizations and experts have raised concerns about perfumes potentially affecting a dog's sense of smell.

Some animal welfare organizations have raised concerns about the high cost, over $100, of Dolce and Gabbana's luxury perfume for dogs.

The alcohol-free fragrance mist for dogs created by the Italian fashion house, priced at £83 ($105) on its U.K. website, was inspired by Fefé, the pet dog of brand-owner Domenico Dolce.

The product page on the company's website states that the scent has "fresh and delicate notes of Ylang Ylang, Musk, and Sandalwood" and is packaged in a green lacquered glass bottle with a 24-carat gold-plated paw on it.

Fefé can be applied to a dog's body by avoiding the nose area or by spraying it onto a pet owner's hands and then brushing or rubbing it into the dog's fur.

The Safe Pet Cosmetics program has certified Dolce and Gabbana's new product as suitable for animal use.

Some animal welfare organizations and experts have raised concerns about the fragrance, warning that perfumes can disrupt a dog's sense of smell.

The RSPCA in Britain cautioned against attributing human traits to dogs, which can create confusion about what dogs and humans enjoy.

"Dogs use their sense of smell to communicate and interact with their surroundings, including people and other animals, according to RSPCA Senior Scientific Officer Alice Potter. To ensure their well-being, it is advised to avoid strong-scented products like perfumes or sprays, especially those that dogs find unpleasant."

A product like Fefé, if present for more than a few minutes, could negatively affect dogs, according to Donald Maurice Broom, professor of animal welfare at the Cambridge Veterinary School.

Broom stated via email that a dog's world is full of subtle odor information about other dogs, humans, food, and potential danger. A strong odor would mask much of this, resulting in negative effects on the dog. It would be like the dog trying to distinguish visually when kept in a blindingly bright light.

The professor pointed out that exposing dogs to sweet-smelling oils like lavender for a brief period can be calming for them. Additionally, oils such as ylang ylang, which is included in Fefé, can also have a positive effect on dogs.

Some "lightly-scented products" that do not use aversive scents or interfere with a dog's sense of smell can have a calming effect, as noted by the RSPCA's Potter.

Potter advised that while owners may want to give their dogs gifts to show their love, it's always best to choose presents that are enjoyable and beneficial for the pet, such as a new toy or tasty treats.
