hiya, i have 2 beautifull girl labs when we got Daisy last year little did we know the trouble we were going to have with her tummy . She too had been fed by the breader on bakers but she had the runs before we even fed her . first thing she did was a pile of slimmey greenish poo in the garden I put it down to nerves and a new enviroment but it continued, I didnt want to feed her bakers as i had heard it was bad for them so we bought what i thought was a good food eukanuba puppy she didnt improve i thought as she already yhad the runs changing her food competely wasnt going to make much difference . This went on for a week till we were told about jwb so i attempted to change her on to that over the period of a week still we had the runs I took her to the vets to see if there was something else that it could be, our vet was great she told us about trying just rice and chicken for a few days she gave her stuff to stop the runs she checked her for worms took blood samples we did all the right things . Nothing was medically wrong with her she had just had a poor start by being fed bakers which had caused her to aquire a food intollerance other than the runs she was normal , our last attempt was to put her on Royal Canin hypoallergenic ,she was on this for a few days when we noticed things looking better and within a week she was pooing normally we used this on the advice of our vet as its not something a young pup should be on for too long as its not callorific enough for there growth , in total she was on this for 5 weeks after that we weaned her on to Royal Canin labrador junior sticking to the same brand and doing it slowly meant her runs did not come back . food intollerance in young dogs when they havnt had the best food to start with is quite common it can take a while to get them back on track . Watch what else you feed as well no raw hide chews often they are made from pork hide which can be an upset to an already sensetive tum just stick to the food so that you can elliminate any other factors . I ve had some real traumers about food in the last few weeks when we took on another lab at christmas i did a bit of research into food and was amazed at how many are made by the same few companys and how many of them contain bad addatives and things you would rather you didnt know about such as diseased dead animals from abatoirs its scary if you research . i guess make sure your pup has been given the all clear from the vets and try feeding a food such as Royal Canin hypo its based on soya protien it really worked for Daisy then you can gradually get her on to something better for her age hope all goes well with the pup let me know how you do if i can be of any other help please ask .
