Excellent product I have used with all my dogs.
I live in a somewhat rulal area and I have never been troubled by fleas on my dogs.
I highly recommend this product and frequently encourage my friends and family with dogs/cats to do the same.
In the past I have purchased a year's supply at the Los Angeles County Fair but year I was unable to attend.
Thank you so much for carrying the product and I will continue to purchase from you as long as I have dogs.
