My dog suffers from diarrhea occasionally and constipation occasionally.

OK, that's much better than "sensitive digestion" :-). Could the
diarrhea be at all stress-related? From what you say later on,
it possible that it might be cat-poop-intake related.

The vet he has had most of his life, a personal friend and a good vet, said
that anything fatty can give him pancreatitis, and is basically dangerous to
feed him.

That's true of all dogs, although some breeds are more prone to
pancreatitis than others.

I feed him Pedigree kibble, with some canned Pedigree dog food
mixed in.

Now, you KNOW we're going to tell you that Pedigree isn't a very
good food, right? :-) Usually I'd say "if it ain't broke, don't fix
it" but in this case you might consider trying a higher-grade food.

I mix enough for the two dogs (#2 a 70# Lab/Rott mix), and as of
late, have been spooning his dish with more kibble and less meat from the
can. That is seeming to help.

OK, you're being observant and adjusting as necessary; that's
great.

You do realize, though, that canned food is more for the owner's
benefit than for the dogs'? It "looks" meatier and therefore tastier,
but that's all psychological. It's mostly water and as a result is
relatively more expensive than kibble. You might well actually end
up saving money by feeding a higher-grade kibble and cutting out
the canned food altogether.

I have used pumpkin on him when he gets bound up, and it releases
him promptly.

Good. As I think I said before, pumpkin is high in fiber, so it's
actually good for both diarrhea AND constipation, just like eating
bran regularly is for humans. So you might want to consider supplementing
him with a tablespoon or two a day on a continual basis and see if that
makes any difference in his elimination problems.

BTW, while I'm giving you several different suggestions here -
try a higher grade of kibble, supplement with pumpkin, etc. - I am
definitely not suggesting you try all of them at once! Try one thing
for at least one month - two would be better - and see if that makes
any difference. Then adjust as necessary. If you change too many
dietary things at once, it would be asking for problems with ANY dog.

One problem which I have not found a control over is him getting into the
cat's nuggets outside. Must be the cat is going now where they can't get
to, because he'd take that over a piece of raw liver.

Ohhhhh yeah. Kitty poop is candy to dogs - they find it delicious in
part because of its high fat content, for what that's worth.

I feed them about half a portion in the morning, around 6AM, and a
full portion about 6PM. Neither has had weight fluctuations, and
the vet says they are both trim, and not obese.

Two meals a day is good. Not being obese is very good. Corgis tend
to be eat-till-you-burst dogs and can easily get overweight, so you're
obviously doing something right.

We do have table scraps all the time, but I am reluctant to give it
to them. I might be passing up perfectly good food for them.

Personally I think it's a better-safe-than-sorry kind of thing,
especially since you know that one of your dogs has issues with
diarrhea to start with. (My first Briard was very prone to stress
diarrhea and I'm the veteran of more trips outdoors in the middle
of the night than I like to think about! :-() I'm not going to say
that I've never put table scraps in my dogs' food - I definitely
have - but I'm careful about what I give them, it's an occasional
thing, and leftovers never make up more than, say, 10% of any given
meal. And with your Corgi's history, I'd be especially careful -
as I said, better safe than cleaning up diarrhea from a white
carpet. (Yep, BTDT...)

Just trying to become better informed.

:-) As we all should be. I too have learned a lot here. Good for
you for asking questions.
