Dear Ann,

Defendex shampoo does not contain ivermectin which should be avoided in collies because they can have a very permeable blood brain barrier and ivermectin can get into the brain. You can use DEFENDEX shampoo but only a small amount because it is so concentrated. I usually dilute it first and apply to the coat so that the amount used is limited. If you should notice any abnormal response (possible allergen) do not let it stay on the coat longer but rinse it off. Be sure you rinse it off well at the right time.

Please let us know if you have any other questions.

Best regards,
