Before flea season hits hard this year, you might want to check with Frontline's customer service. Their representive came into our vets office while I was purchasing my K9 Advantix. I was having to purchase one for under 10lbs and one for over 10lbs. Mine weighed 11 lbs and one was 5.2 lbs. I was asking about the frontline due to it being for under 20lbs. Another client said she split the dose between her two minature pomerians. He told her that was something she should not do due to it compromising the effectiveness of the product. He also stated the company had more calls that flea season, that the product was not effective against fleas. When questioning the customers, several said they were spliting the dosage. I stayed with the K9 Advantix because of the lower weight dosage. But had to apply every 28 days instead of 30 for it to keep its effectivness. We live in the woods and go weekly to the farm so they are exposed to alot of those pesty creatures!!! Alot could also depend on where you live. Fleas don't really exist is CO. Our guys loved living there, especially the outdoor golden retrievers!!! I saved alot of money living there with 4 dogs and 2 cats... |
