Candle, you are just like how i used to be. I did same exact thing you are doing, i was accidentally feeding my last dog crappy dog food. I adored my last dog, but, i just had no idea how crappy dog food can be.
RULE OF THUMB---------IF YOU CAN BUY YOUR BRAND OF DOG FOOD IN A HUMAN GROCERY STORE==> IS ABOUT 99% CHANCE IT IS CRAPPY DOG FOOD.
Pedigree is one of the worst of all dog foods.
Your vet might tell you "It's fine dog food", but, sadly, many vets don't know/care much about dog nutrition.
Pedigree is mostly a bag of corn (which is indigestible to dogs, it's just a FIBER, just a filler, and many dogs are allergic to corn)
with some byproducts (that is like, hooves, beaks, claws
)
wheat (also a filler, and many dogs are allergic to wheat)
corn gluten (like rubber, is a filler)
and no meat at all in the whole entire bag.
dogs are designed to eat MEAT. And Pedigree has almost NO meat at all in entire bag, instead, it is just a buncha corn and bones ground up,
Don't feel bad, i did same thing, who knew? Who knew ppl can sell such crap to us?

You can NOT find one dog nutrition expert to say anything good about Pedigree.
If you do decide to swap out Tucker's dog food, you can donate the leftover Pedigree to the local dog pound, they'll be glad to have it.
IF YOU DO DECIDE to stop feeding your dog "Pedigree" dog food, here's how you can swap it out:
(this is super slow transition since Tucker's colon has been inflamed)
After a day of fast/liquids only for Tucker's diarrhea,
and then a day or two of the bland diet,---IF NO DIARRHEA HAPPENS,
then you may want to try
to add in
A FEW kibbles of a better dog food,
like just 5 or 6 lil kibbles of the new brand
JUST A FEW KIBBLES into his pototo/chicken mixture...
and then after a few days of only about 6 kibbles in each bowl,
then---if no diarrhea develops-------------then begin to add about 15 kibbles
for a day or two, (going real slowly, since Tucker's colon might still be inflamed)
and then, after a day or two of 15 kibbles into each bowl,
then---------- make his bowl be about 1/3 kibble, 2/3 potato+chicken
then after a another few days of that mixture,
then advance slowly to about 1/2 kibble, to 1/2 'chicken + potato bland diet'.
and then, after another few days,
if no diarrhea,
then try 2/3 kibble with 1/3 of his bland diet.
then, after a few days of that,
then, try 3/4 kibble with 1/4 bland diet....
might be worth a try??
