This might be of interest to owners of dogs who have frequent tummy upsets. I have a black lab, now aged 20 months, who up until she was 18 months had frequent loose stools with the occasional firm one. I changed her biscuit four times during that time. I searched the Internet for possible causes and some help. All l could find was "try grain free" and it did help a little at first but then soon reverted back to loose. The vet recommended the GI biscuit and wet food but the end result was the same, and it was very expensive. I asked the vet about raw diet but she was very against it. In desperation l decided to experiment by cutting back the biscuits from 300g per day to 100g which l feed in the evening along with 125g of wet food, 125g of cooked veg eg. Broccoli, cauliflower and carrots and a sardine in olive oil. In the morning she has 1 1/2 raw chicken wings, jointed. It has now been three months and she has not had a single upset. Plus her coat is exceptional, beautiful and glossy and the slight occasional dandruff has gone. I think cutting back drastically on the biscuit has been the key.
