TropiClean Natural Flea & Tick Shampoo Max 20 oz.

The 20oz bottle has lasted me almost two months with weekly baths for my two dogs, which is way better than the tiny bottles I used to burn through. Suds up nicely and rinses clean, and I haven't spotted a single flea since we started using it.

Our lab mix picked up fleas at the dog park and one bath with this stuff had them dropping off before I even finished lathering. I like that it's a 20oz bottle with natural ingredients but still strong enough to actually work, and his coat didn't dry out at all.

I was skeptical about a natural flea shampoo actually working, but after one bath my lab stopped scratching completely. The 20oz bottle goes a long way since you only need a small amount lathered in, and it rinsed out cleaner than the medicated stuff I used before.
