Hello just joined the site and have been enjoying researching dog foods. My 3 year old active male terrier has always eaten premium quality kibble, both grain and non grain, poultry, fish, game, all types etc without any issues, reactions, or intolerances/allergies. He's very healthy and a good weight. Recently I was looking into changing kibble for cold pressed having read alot about its qualities. So over quite an extended period of time I tried small bags of Gentle original, Guru Surf and Turf and Full on Feast and Walker and Drake. Both grain and grain free examples. Actually have spent a small fortune on trying cold pressed as I ended up not using a lot of the food! This is because the mystery is, that although my dog clearly loves eating all the food with relish, it just does not seem to agree with him as despite changing all the foods by gradually feeding a small quantity increasing each day and weighing the portions, sadly with all these cold pressed foods he throws up clear bile a couple of hours after mealtimes (not the food just thick bile) and keeps dry retching throughout the day. Other than that he is fine and not causing any other problems, stools very good and consistent too. Each time I transitioned back to kibble after trying a different food, the retching/bile stopped immediately. So have resolved to keeping with kibble which is a pity as I thought cold pressed would work. I'm just wondering if anyone else has experienced these symptoms with cold pressed food, I scrutinised the ingredients in all 3 brands compared to his previous kibble as thought I may recognise something different but just don't know what was in them that he reacted to. Maybe it's just the way the cold pressed is made that doesn't agree with him for example the different texture? Incidentally the mystery somewhat thickened when my sister had some Nutravetal cold pressed food (poultry) she gave him to try recently and the retching/bile was completely absent with this food, finally! So again I cross checked ingredients against the other cold pressed foods but didn't spot anything that stood out of the ordinary that was in the others and not Nutravetal. I did notice the Nutravetal cold pressed food has a very different texture and consistency to the other foods with much harder pellets which don't break up and less 'dusty'. Could that solve the issue I wonder if it's just the texture afterall? I have decided to stick with kibble as Nutravetal protein levels are much lower at 21% on the poultry variety which is a pity (could that perhaps be a factor too as others had higher protein levels? ) as it did seem to agree with him. Am reluctant now to try other cold pressed brands with higher protein so have finally given up altogether after all my efforts and now back on Eden Country Cuisine which he has always enjoyed and is loving his mealtimes.
