I don't usually write reviews but feel compelled to do so following our experience of using Tails dog food. The first two bags we had appeared okay but after a couple of meals of the third bag our dog was taken seriously ill with diarrhoea and vomiting. We initially thought he must have picked something up whilst on a walk so after three weeks of treatment on special diet and antibiotics from the vet we started on the tails food again. This time our dog started having diarrhoea after about 3 days on the Tails diet so we went back to the vet who started the same treatment again which lasted for about 4 weeks this time before we put him back on the food he was on prior to the Tails food. I have been in touch with Tails and at first they appeared to be taking it seriously and asked me to keep some of the food as they would want to test it to see if it was contaminated. However, they never followed this up and after waiting three weeks since my last email to them I have decided to write this review in case anyone else has had unexpected illnesses with their pet. This has been a very distressing and costly process, but luckily our dog has now recovered and is back on the food he was having prior to me falling for the Tails marketing of having bespoke food for your pet. I'm hoping Tails will now take this seriously and have the food tested and warn other dog owners of potential problems with their food.
