Vet Review | Currently under review | Coming soon | I recently completed a small clinical trial using Flea 4X topical product for dogs in my veterinary clinic. And I must say that the initial reports on efficacy and safety has been excellent. With the main ingredient being the tried and tested fipronil, this product is very effective in controlling fleas, ticks, chewing lice and mosquitoes. It is also labelled to control mites that cause sarcoptic mange in dogs as well. This product is a wonderful generic alternative to the Frontline product that has been out for years. Clients have loved the economic savings of this product over similar topical flea and tick preventatives. It is manufactured exclusively in the United States, as well as having the trustworthy and reliable 1800petmeds label on the packaging. It is also water proof for those canine patients who spend a lot of time outside and/or swimming during the summer months. Clients are reporting back to me quick flea and tick killing that lasts up to several weeks in treated pets. I highly recommend this product to those canine guardians seeking out an effective and economic alternative to similar products on the market. |
