I'm a professional dog groomer who is well known for being "holistic". I wasted so much money over the years trying to find the one flea shampoo and spray that would eliminate fleas safely and not put a pet's health in danger. I found "Vet's Best Spray On Flea Shampoo" and "Flea & Tick Spray" at a small holistic food store. I twisted the lid off, gave it a sniff, and put it immediately in my basket. This stuff smells so good, if you like that cinnamon spice scent. There are no offensive fumes that burn the pets eyes. I was so happy when I found the product to actually work. I use the spray on shampoo first. Once the groom is complete I use the spray. Mosquitoes are bad in the south and this product uses essential oils to repel them. Perfect for before walks on both me and the dog! This product kills fleas on contact. It does not repel fleas. . It's pretty important when I'm getting paid to de flea a dog that I do it right and most importantly, do it safely. I found pesticide products have horrible side effects such as vomiting, loose stool, and even neurological side effects. I like that I can use this product on my client's dogs and feel confidant that it will not only work, but it wont put me out of a job by hurting a dog! Trust me you should get both the spray on shampoo and the spray for a full arsenal defense against fleas and mosquitoes! Last but not least I'd like to add that it's rare to find a flea product that works on cats that is safe to use. Cats are so sensitive to flea products, and they are the worst to get fleas. I"ve used the spray on my cat, careful to lift the hair and aim for the skin. Follow the directions to a T and your cat can safely be treated.
