"I love BioSpot Shampoo. After using Frontline for 6 months regularly, our Great Pyr ended up with tons of fleas while on a trip to the lake. I needed something fast when we got home, ran to the store and bought this product. Its amazing! I bought a large bottle thinking I would need it all, however I still have enough for 2/3 more shampoos if needed! Not only does it work wonderfully, but it doesn't take a whole bottle, which is amazing with a Pyr. It lathers great, works instantly, and rinses clean - amazing! It also smells clean and leaves his hair soft! I liked the shampoo so much I started using the monthly treatment - also works wonderfully!"
