Hi Max and Lucy,
What is the protein source in the vet diet? its probably chicken look for a limited ingredient kibble that has chicken, but they normaly don’t have chicken in LID formula’s as dogs can be sensitive to chicken or try a new protein source he hasn’t really eaten before he was probably sensitive to an ingredient in the food he was eating when he was pooing blood, google the food he was eating at the time & read what the ingredients were & try & work out which ingredient he probably is sensitive too & avoid it.
Have a look at “Natural Balance” LID formula’s, NB is really good for dogs with Intestinal problems, IBD IBS the NB has limited of ingredients what you need, then when your dog is doing really well you can start adding 1 new food to your dog diet & try & work out what he can & can eat,.. I added the new food to only one of my boy meal at first, this way I saw the difference in his poos if there was a problem with the food I added when he did his 2 poos a day..
https://www.naturalbalanceinc.com/dog-formulas/special-category-limited-ingredient-diets look at the “Potato & Duck” LID formula, Sweet Potato & Fish & the Sweet Potato & Bison Formula’s as these formula’s are very similiar to the vet diets & they do not have the Garbanzo Beans, some of the other Natural balance LID formulas & their Chicken Small Breed formula has Garbanzo beans, Lentils & Garbanzo beans cause bad gas/wind pain…
My boy has IBD & was on a vet diet & I changed him to Taste Of The Wild Sierra Mountain Roasted Lamb & had no problems but I did it very slowley over a 14 day period I’d do the same when you find a limited ingredient dog food..
also once you do find a limited ingredient food that agrees with your dog then just start adding healthy cooked ingredients to his diet what ever your cooking cook extra & freeze in section in freezer, that’s what I do & for Lunch Patch gets a cooked small meal..but first work out what foods he can & can’t eat…..
