Hi. One and half weeks ago I rehomed a rescue 1 year old lurcher cross. He seems to have horrid tummy problems, with a constantly runny rear. On advice from Pets at Home I started feeding him chappie dried and tinned mixed. It didn't clear so tried adding the old favourite of my mums, mixing with rice and chicken and in the last 3 days have changed to Burgess dried complete for greyhound and lurcher, introducing it slowly with chicken and rice. He's still runny. Am I expecting too much too soon etc blar blar. Thanks.
