Hi,
“I am thinking of changing his food, but I don’t want to upset his stomach”,
his intestinal tract is already upset, if he was doing really well on this Purina Pro Plan Sensitive stomach formula, his poos would be nice & firm, he wouldn’t be drinking & drinking water & he wouldnt be licking his bum…
DRINKING heaps of water- if his poos are soft/sloppy & not firm then he might be dehydrated, something in this formula might be dehydrating him like too many soluble fibers…your dog mighten have problems digesting his foods, your dog might be OK & can digest foods, he might digest his food too quickly like Patch does, so he doesnt need these type of ingredients that are high in soluble fibers that digest in teh small bowel, this could be the reason for drinking excess water??
Licking bum area or rubbing bum on ground/grass could be food sensitivities, something in this Pro Plan formula he’s sensitive too….
or his anal glands are full & need emptying, his poos mighten be firm enough & his anal glands are not naturally emptying now, this happens with Patch when he eats a grain kibble that’s higher in soluble fibers, maize/corn gluten meal, barley, oats, rice, & his poos aren’t firm enough to empty his anal glands…
Have you seen the Purina Poo chart??

I really think alot of his Intestinal problems is to do with FIBER, Soluble fiber & Insoluble fiber & he cant handle too much soluble fiber ingredients as they digest too quickly in the small bowel & he might be like Patch & digests his food quickly anyway, so when they eat foods that are higher in soluble fibers this is when their poos are sloppy & are not firm.
He needs a dry food that has more insoluble fiber & less soluble fiber & alot of grain free formulas have more insoluble fiber ingredients & less soluble fiber ingredients..
Potatoes- Fiber from potatoes comes in both forms, soluble and insoluble, the “insoluble content is higher”. This is probably why dogs with IBS or IBD do really well when they eat a kibble that has potato in it…
He’d probably do better on a Large Breed grain free kibble that has potato?? or a grain kibble that has potato in it…
Make sure the next kibble you try has at least 2-3 meat protein meals as 1st & 2nd ingredients, so there’s less fiber in his diet & more meat but not too much meat 25%-34%, the Purina Pro plan Lamb & Oatmeal Sensitive Stomach doesnt have much meat protein in it, it has more plant proteins which = higher soluble fiber ingredients….
Have a look at Victor, a few people say their dogs are doing really well eating Victor dog food..
Look at the Victor Select formula’s, Victor uses the Montmorillonite clay.
