I need help with what to do about my puppy's food. 9 month old spaniel, lots of energy. He needs food without any chicken or gluten. On Arden grange from the breeder but had to be removed from that due to the chicken/gluten issues. moved onto Wildways which was brilliant for several months but he was still showing problems related to his rather niche medical issue and we think it's the chicken.
So I searched to find a non-gluten, non-chicken kibble. I thought Millie's Wolfheart would be the answer and he's been on that a few weeks. Good news, his medical issue seems to have calmed down, so we do think chicken was the issue, but he is having awful digestive issues on it despite introducing it very gradually. I phoned millie's who were helpful and they suggested moving off the gundog mix onto agility mix but we are seeing the same issues. I think he now needs a new food because he is having lots of strained runny poos despite being on the lowest food amount, he's losing weight.
I'd prefer kibble if possible because I have no freezer space but willing to try a tray type food if it's the only option. I'm a bit unsure what this involves though (is it just open a tray and chuck it down, how many trays do they need a day?) and whether it needs supplementing?
