A great set for the pet lover in your life! Each set contains a 4oz bottle of pet shampoo and a 4oz bottle of deodorizing pet spray for in between washes. Both products are safe for sensitive pet skin. They are scented lightly to avoid any irritation. The pet spray is only scented with essential oils, as it is designed to be sprayed on the coat and not washed off. The shampoo is a very gentle formula, as it can be used on human babies. The spray is also very gentle and is infused with aloe vera to protect your pet's skin and coat.
