Pet odors are often caused by natural oils, sweat, and waste products from animals like dogs and cats. These odors can be more noticeable in certain areas of the home, such as carpets, furniture, and bedding, where pets frequently spend time. Regular grooming and cleaning can help reduce these smells. Additionally, pet odors can be influenced by factors such as diet, health, and hygiene. For instance, a dog's diet may affect the smell of its skin and breath. Keeping pets clean and maintaining a tidy living environment can significantly minimize unpleasant odors.
