Great product, easy to use


Received promptly thank you


Excellent service and quality


Did not work on a greyhound of around 32 kilos. Since used another product and that worked....

On 22 Aug 2017 Pet Drugs Online responded:
Hi sorry to hear the flevox was unsuccessful, some products are more effective on different pets. The flevox is a tried and tested product but only kills adult fleas and not the eggs and pupae so it will take some time to control the fleas. Glad to hear you found a product that was effective
Best wishes Shirley


Used every 8 weeks and my dogs never have flees. Just the same ingredients as more expensive brands.


Great delivery, good price very easy to follow instructions.


Good price and fast shipping


Fantastic value and works great


Cheaper than frontline and just as effective


This product is easy to use.
