Petwell have been supplying Lypex for my little dog Timmys chronic pancreatitis for a couple of years now. The cost is so much lower than the vets and the service is always prompt. An order once went "missing" (definately a courier problem) and I contacted Petwell for help as I was running desparately low and my dogs continued good health relies on daily Lypex so I was beginning to panic. Petwell were brilliant, they sent out another batch by special delivery and gave me a discount voucher for the next batch. They also emailed me to check that all was well with Timmy. I wouldn't dream of using any other supplier.
