Our Natural Bug Repellent for Dogs has been specially formulated to provide protection against all types of biting flies, fleas, ticks, mosquitoes, and other insects that pester your pet. Canines are especially sensitive to citrusy scents, so our repellent excludes essential oils such as citronella or lemongrass, which may be irritating. Our blend also excludes essential oils that are toxic to dogs such as clove oil. Active ingredients include essential oils of rosemary, thyme, peppermint, cedarwood, and geranium. Water and glycerin are the only other ingredients. We do not use any chemical dispersants in our formula. Not greasy, with a light feel when sprayed on skin. Spray on clothing and gear without staining or damage. Our insect repellents are all DEET-free, soy-free, vegan, and cruelty-free. Not for use on cats. Our Natural Bug Repellent Spray for Dogs comes in two sizes: 8 oz (aluminum bottle) and 16 oz (post-consumer recycled plastic bottle).
