Vet Review

Within the past year there has been an exciting development in the battle against fleas and ticks.For years, veterinarians have relied on topical medications for control of fleas and ticks, however many formulations are greasy, as well as some sensitive pets may have an allergic reaction to contact some of them. Many clients also worry about the exposure of humans to topical flea and tick pesticides. That is why the exciting new product from Merial known as Nexgard has been such a welcome addition to our flea and tick treatment and prevention options. By using a the ingredient, afoxolaner, Merial has come out with a new product that most fleas and ticks are certainly susceptible. Dogs also LOVE the soft, beef flavored chewable, even without meals. It has also been shown to be safe at up to 5 times the recommended dose.The only down side to this product is that the parasites must bite the dog to be affected, and in some cases this may take up to many hours for this to occur. However, studies as well as clinical experience with this product show that is it very effective in preventing Lyme, Anaplasmosis, Ehrlichiosis and Rocky Mountain spotted fever. This makes it essential as part of any year round parasite prevention program in our dogs. The only rare side effects I have seen are mild digestive upset. I therefore give this product an overall rating of a 4.5, with an ease of use of a 5 out of 5.

This is one of my favorite and most effective products in preventing tick infestations on dogs of all sizes, as well as preventing the tick born diseases such as Lyme disease, Rocky Mountain Spotted Fever, Ehlrichia and Anaplasmosis. When some of the topical products have failed in some patients, I have found this collar quite valuable in significantly cutting down on tick burdens in these dogs. The effects are long lasting for up to 3 months preventing ticks from even attaching to dogs, and thus cutting down on tick exposure to humans as well. The only problems in terms of efficacy I have even seen with this product is when animal guardians apply the collar too loosely to their pets, which can cut down on its efficacy against ticks.. In order for this collar to work effectively, it must be fitted snugly against the pet's neck, where one is just able to get two fingers under the collar. If the collar is applied too loosely I have occasionally seen pets ingest this collar, leading to serious systemic reactions. The only other downside in using this collar is if the pet spends a significant time swimming during the warmer months. The collar's efficacy is cut down significantly if it is submerged in water or exposed to drenching rains. However when properly fitted to a dog's neck, this is one of the most effective products in preventing tick infestations on the market.

There is an outstanding new comprehensive internal and external parasite control product called sentinel spectrum, which combines 3 excellent worming medications that treat and prevent a wide variety of parasites from heartworms, intestinal worms ranging from tapeworms to whipworms, as well as controlling flea infestations. That is 6 types of parasites controlled with one pill. That is a wonderful benefit of this product, along with the tastiest beef flavored tablet. The only down side to this product in my experience and opinion is that it does not kill or repel fleas, but breaks the flea life cycle by preventing adult fleas from laying eggs, as well as killing the eggs. Adult fleas still may bite your dog, which may cause allergic dermatitis in some sensitive animals. I have also seen occasional pet vomit on this product, which is usually avoided by giving with a meal. A wonderful benefit over topical parasite control measures is that by combining all of the wonderful ingredients into a pill formulation prevents exposure of the humans in the household to chemical pesticide residues. I give this product an overall rating of a 4, with a taste of 4 and ease of use of a 5.
