Vet Review Belonging to the latest generation of flea/tick parasiticides(known as Isoxazoline medications), these palatable, beef flavored chewable tablets kills fleas quite effective, with most adult fleas being killed within 8 hours. One of the downsides, as compared with Vectra 3D is that Credilio does not repel either fleas or ticks, and has no effect on biting mosquitoes, which are the main vectors that transmit heartworms to dogs. Credilio and products of its class are one of the most effective products against several species of severe disease transmitting ticks, including ones that transmit Lyme Disease, Ehrlichiosis, Rocky Mountain Spotted Fever and Anaplasmosis, which have been increasing in incidence in recent years. As with other members of this drug class, we have also used this drug in treatment and prevention of both demedex mites and scabies mites, although this is an off label use. Giving with a full meal reduces risks of digestive reaction. Overall the tablet is well tolorated, but occasional diarrhea, vomiting or digestive upset is seen. I would look to one of the other products like Vectra 3D, if there is a history of significant neurologic disease or seizures. I give this product an overall rating of a 4 out of 5. In recent years, the company Bayer has developed a revolutionary flea/tick collar for both dogs and cats that is highly effective, especially in flea control, as well as providing moderately effective tick control. The most exciting aspect of this product is that it provides BOTH repelling and killing of fleas and ticks for up to 8 months!! While it is somewhat expensive, it is actually cheaper than purchasing 8 months of Revolution, Advantage or Frontline. In many areas of the country, this protection will last the entire flea and tick season, by just properly applying the collar. Another major advantage over collars developed in prior years (i.e. Preventic collar) is that Seresto is water resistant, and can be worn with confidence, even by dogs who frequently swim. The collar also has no odor, as well as a powdery, soft feel, in addition to leaving no greasy topical residue, like many of the other topical flea and tick products available. The collar is safe if chewed and/or even eaten by the pet, which was a problem with the old Amitraz based collars such as the Preventic collar. The Bayer company has also made it radioopaque, in case an overzealous pet did ingest the collar, so as to allow radiographic tracing and/or location should it possibly get caught up in the intestinal tract. The collar also has unique technology, in that the release of the active ingredients is triggered by friction of the movement of the pet's hair and body heat. The cat collar even has a break-away apparatus to allow for the pet to safely detach from the collar should it get caught on something outside. The reflectors on the dog product also allow the dog to be seen during the hours of darkness. While the collar is very safe for most pets, I have occasionally and rarely seen reactions in sensitive, geriatric or chronically ill pets. These typically involve transient itching, redness and hair loss at the site of adherence to the skin. While most of the time this will resolve on its own in a week or two, occasionally pets will develop enough irritation where the collar may need to be removed. The major rare systemic reactions seen in sensitive pets are mild lethargy and decrease in energy, but even more rare is the development of neurological symptoms, including weakness and/or seizures. I don't recommend that it be used in pets with a history of seizures and/or neurological sensitivity or reactions. While it is amazing for killing and repelling all stages of the flea life cycle quite quickly, it can sometimes take up to several days for the maximal effects to be seen with tick control and prevention. I, therefore, give this product an overall rating of a 4 out of 5, with an ease of compliance and efficacy of a 4.5 out of 5.
