This item is Fantastic for Spring Summer and Fall Seasons and for all year in the warmer climate states. The combination of 9 Essential Oils were carefully selected and measured to create the best safety & effectiveness for pet use and to create a more pleasant smell. For use on PETS and PEOPLE!.  My crew Loves this brew and I have not had any issues with my pets, but it is always possible for cettsin pets to be sensitive to certain things just as people have allergies, so I suggest you do a light trial first, then apply as directed. The oils used are listed on the label, but the measurements of those oils are not. We always suggest not trying to make these things yourself as measurements can be crucial. Currently making these in 4 oz fine mist sprays that helps this product go a long ways, but I can make 8 oz bottles upon request. Call or text for requests. 1-608-477-2192
