Thanks, was in such a hurry I spelled it wrong!!  LOL

Talked to doc on phone and we have to wait another couple of days to see if it passes first.  Then we will do tests.

Hubby grabbed one of my horses smz's and gave it a try last night, and already is up and moving some, so he took another this morning.  Probably NOT the right antibiotic, but I know people who take them often, so it shouldn't hurt him any.

Actually Gardia is sensitive to Trimethroprim which is one of the antibiotics in SMZ's.  BUT he has to take the correct dose for them to work completely and isn't.

If you do not know where he may have caught it you may want to have your water tested if your on a well.  We lost a litter of pups last year to 4 micro's and Guardia was one of them.  Ended up it was our well and had to have it shocked.
