Our Cocker have this year the grass mites caught quite bad, so we were looking for a natural solution. I must say that neem oil has really helped, even overnight, the bites have improved significantly. BUT, and this should be borne in mind that stuff stinks terribly (after onion somehow). That's really just what strong noses or people who your dog is not quite as close as we come because it's a really pungent smell, which remains a long stick. Was funny that we have received the product without packaging or package insert, or the like ... that came over a bit weird, but there are worse things.
Conclusion: Good product with good effect, but extremely smelly, problematic ordering process
