I learned about this site through a Facebook group. I had no idea a site like this existed, I was always under the impression that you had to take your dog in yearly to get a prescription for good flea meds. look no further, I just received my second delivery, and though customs does take about 2 weeks, the product is as expected and works great. thank you Pet Bucket for helping me take care of my pets without costly vet visits to renew standard medications.
