[pyrnet] Glucosamine allergy?

["Susan Irving" <sirving@rogers.com>]

Has anyone's dog experienced any diarrhea from glucosamine?  I started
putting it on the dog's food a few days ago because Jasmine is seeming a
little stiff lately (she's just turned 4.) She is OK, but Seamus has the
runs, and it is just liquid.  There has been no other change in diet so I'm
assuming it is probably the glucosamine.  I have heard that some humans find
it hard on the digestive system, and am wondering if perhaps Seamus is
allergic to it. Anyway, I'm taking him off of it for awhile to see if there
is a change. Just curious to see if anyone else has had the same problem.
