Ive been doing a bit of research too ive now got 2 labs both 12 months old and our origional dog Daisy is on royal canin and our new one is on some pants stuff that the people we had her from gave us . having the 2 i wanted to get them on the same but the royal canin is quite expensive even with our discount from the vets. So i found pero and asked for some samples wich arrived on saturday of the lab life food its more than there other foods but with the fact that labs can become over weight if not closely kept in check and the whole joint thing i thought the little extra would be worth it. I must say they wolfed it down gave them no tummy trouble after ,and smelt not too bed either . From the makers its free delivery and 15 kilo is 30 quid ive estimated it will feed both of them for about 3 weeks. Im going to order a bag and see how we go, Did any one check out the link someone put on here yesterday about the addatives put in to dog food that was causing real health problems unreal you just dont know food claims on bags is really misleading , having looked further into this ive found that even Royal canin has 2 preservatives in it that are banned from human consumption because its been linked with cancer !!!!!
