Vet Review

The non-greasy, non-odor formulation is a definite plus when used on sensitive patients, especially cats.I find that advantage kills fleas and larvae more quickly than some of the other products out there, often resulting in quicker relief of flea allergy dermatitis symptoms in dogs and cats. Overall I have found it quite safe and have seen the fewest topical or rare systemic reactions in my practice over the years. The main disadvantage I have found is that in heavy flea infestations that the efficacy may wear off in less than one month, necessitating some vets to recommend more frequent off label use of this product every few weeks. It also does not control ticks as well on dogs and cats. I find that advantage works most effectively when combined with good environmental flea control at home.

The fast-acting nature of Advantage XD is one of its standout features, as it starts killing fleas within 30 minutes to 4 hours, providing rapid relief for cats. Its long-lasting formula is another major benefit, offering protection for up to two months per application, which is twice the duration of many other flea treatments. The active ingredient, spinetoram, is derived from natural soil microbes, making it a preferred option for veterinarians concerned about using harsh chemicals on sensitive pets. However, as with any topical treatment, some cats may experience mild skin reactions like irritation or hair loss at the application site. Despite this, Advantage XD remains a top choice for its effectiveness and ease of use, though in cases of severe infestations, veterinarians may recommend additional environmental flea control measures.

As most exterminators will tell you, the battle with external parasites and pests is an always evolving battle, as over time, parasites will develop partial resistance to products that had once worked almost perfectly in the past. This has been my experience with some of the older flea/tick formulations and has been reported by my veterinary colleagues and clients alike on occasion. While the older products are mostly still effective, companies are always researching new formulations to stay one step ahead of the development of resistance in the parasites. One of the latest formulations, Frontline Gold takes advantage of newer technologies and now has added an additional insect growth regulator, Pyriproxyfen, to its original formulation, to help enhance the efficacy of the Frontline plus product. The Frontline product is thus able to kill the next generation of flea larvae and eggs even more effectively by breaking the life cycle of the flea. The likelihood of flea immune resistance to this new triple action formula is thus significantly reduced. Given the increasing global warming seen in recent years, the expanding and increasing flea populations in heavily infested areas, however, do require a truly holistic approach by the animal guardian in treating the home, environment and yard for optimal flea control, as it is important to keep in mind that much of the flea life cycle still occurs in the home. While many clients find the more easily applied, self-puncturing tube dispensing method(often only requiring the use of one hand) to the old product, other clients find it difficult to see if all of the product has been dispensed from the colored tube. This new product, however, is quite effective, with only rare topical irritation at the site of the application an only rare complication. With that being said, I give this product an overall rating of a 5, with an ease of application of 4.
