I have tried these type of products, I tend to think of them as repellents, at best, they also keep people away from you and your dog because they stink (just my opinion) 🙂
Consult your vet for recommendations on adequate flea/tick control products.

PS: There are a lot of reviews for the product at the link you provided.
I have not used this specific product. It might very well be a lovely dog shampoo.
