After going to the chemist to buy flea treatment for my dog I was advised to search the internet as their prices were in the region of £30.00 I searched the internet and came upon petwell. I was always told that if something is to good to be true it usually is. However in this case that theory is wrong. I was dubious prices were less than half compared to the chemist and a leading pet shop. I decided to take a chance. I received my dogs frontline in 4 days. Then I bought 6 months supply. I have 2 dogs and a cat and I now buy all my frontline from petwell. 100% happy and my pets are too
