It just is a fact that you can't just go solely by the dosage recommended. Key word being "recommended".(their CYA)
When the testing is done exclusively on one type and size of dog, and the parameters for different size dosages are set forth by 'calculations' derived from that one size/type dog testing? The pet owner needs to know and understand that the dosage recommended may be too much or too little for their particular pet.
Some product dosage amounts there is leeway, others deadly.
It's just a guideline, a poor one, but a guideline none the less.
THIS is what I would be more concerned about regarding this product as expressed by our very own government agencies.
"Spot-on treatments are not monitored by the government once their registration has been approved. Unlike drugs approved by the FDA, the officials said, flea and tick treatments do not undergo post-market surveillance."
They did the minimal testing on Beagles, calculated the dosage for all other size and weight dogs and released it to the public with no scrutiny of any other governing agency to ensure it's safety for all other size and breed of pets.
Sooo, if you own a Beagle, there's good news that what ever the dosage recommended is on the label it will be the correct dosage for YOUR dog! :B:B
