Merial Animal Health has launched Certifect, a new POM flea and tick treatment for dogs.

The product was launched at a series of presentations by the survival and bushcraft expert, Ray Mears (pictured right) last week.

The connection between Ray Mears and a new flea and tick treatment for domestic dogs became clear as he recounted his experience of contracting Lyme Disease in the UK. Indeed, by the time he'd finished describing the crippling pain he'd suffered and the industrial quantities of morphine and tramadol he'd needed, most vets in the room were probably ready to place an order for a tonne of the new product.

But to dismiss it as just a polished marketing exercise would be wrong. According to the Health Protection Agency, cases of Lyme disease in people have risen from 296 in 2001 to 953 in 2010. It is thought that because the disease is difficult to diagnose, it is likely to be significantly under-reported. In addition, a study by Faith Smith from the University of Bristol last year found that of 3534 dogs examined, 810 (22.9%) were carrying at least one tick.

So, what about the new product? Well, it's essentially Frontline Combo (fipronil + the insect growth regulator, S-methoprine) but with added amitraz. At the low dose contained in Certifect, Merial explained that amitraz doesn't demonstrate acaricidal properties itself, but instead potentiates the effect of the fipronil and causes ticks to detach or fail to attach. It also causes ticks to move around more than they do normally, thereby exposing them to more fipronil.

Merial says the acaricidal effect of Certifect can be seen two hours after application, and that more than 90% of ticks are eliminated within 24 hours. After treatment, Certifect prevented 94.5% to 100% of ticks attaching until day 29, thereby reducing the risk of disease transmission. In terms of integrated flea control, think Frontline Combo.

Certifect can be used on pregnant and lactating bitches, on puppies from 8 weeks weighing more than 2kg, and on dogs which live in households with cats.
