Can anybody help please! What is the best food for a whippet. Lilly is 2 and a half now and is still suffering with an upset tummy! It was ok for a while but now seems to be back. We've been to the vets constantly. Poo tests come back showing nothing is wrong, so do blood tests. The only thing that works... while she's on them, is Tylosin, but as soon as she's off them it comes back within 3-4 days. She's on Royal Canin Gastro Intestinal wet food from the vets. I put a spoonful of cooked mince in it so she will eat it. We treat train with Pooch and Mutt puppy development mini bones. To stop her being sick in the mornings (bright yellow bile) I give her 3 Lily's Kitchen Bedtime Biscuits at 9.30pm (which seems to work). She's always ill at night around 2am then has to go out every hour from then until 6am. She can do a normal poo in the day then be ill again in the night. Her last meal is 6.30pm. She seems a happy healthy dog apart from this. She is naughty and eats things on walks though. I've tried to train 'leave it' but she's very strong-willed. I've been told a raw diet may help. Any thoughts and help welcome. Many thanks, Sandra.
