I was using Frontline Plus for my dog from past 4 years but all of a sudden it seemed that the treatment was not working anymore. There were fleas all over my Scarlet. I am a regular customer at BudgetPetCare and have never experienced the bitter side of it. They also have a free veterinary service which I thought would be the right thing to do. I talked to their vet about the situation and he guided me through very well. He explained me that due to continuous use of any particular treatment, the parasites become immune to them. I just need to change the treatment and he suggested Advantage for my Scarlet. I am so happy to see that my pooch is finally free from fleas. I tell you, BudgetPetCare is the most reliable seller I have known so far!
