SARAH: What is the difference between founder and laminitis?
DR LYDIA GRAY: I think that's an excellent question
and I get that a lot.
And I know people think it a lot,
but they think it's a stupid question maybe,
and don't want to ask it.
But this person did, so brave on her part.
So laminitis is generally accepted
as the acute situation.
And founder is chronic laminitis,
especially once some mechanical changes
have occurred in the foot.
Like the rotation or the sinking that you hear about.
So-- and it's not even that simple.
Because laminitis-- there's three stages.
There's the developmental, so some insult or injury
happens to the laminae in the foot.
And you don't even know about it, but it's cooking,
it's stewing, it's building.
So that's the developmental phase and that
can be a few hours or days.
And then you enter into the acute phase.
And that can be from the first time
that signs appear to about 72 hours, which is three days-ish.
After that, you enter into the chronic phase.
And so that's from 72 hours on, or it begins
when physical changes occur.
So maybe your veterinarian takes radiographs
and you see the bone in the foot,
the coffin bone pulling away from the hoof wall,
so the sinking.
Or even worse, the whole coffin bone just sinks to the bottom.
So this is a rotation and this is sinking.
And we tend to think of those physical changes
in the foot as founder and then the development
in the acute stage as laminitis.
Although they are used interchangeably and that's
not wrong, but if you want to get down to the nitty-gritty,
that's how it's described.
SARAH: Is it fair to say all founder started as laminitis--
DR LYDIA GRAY: Yes.
SARAH: But not all laminitis becomes founder.
DR LYDIA GRAY: Yes, I like that, I'm going
to steal that for next time.
SARAH: That's awesome.
DR LYDIA GRAY: It's good.
