Has anyone tried Lax'Aire?

The Vet gave me it to use for Cocos Constipation. She cried in the Pan last night but didnt go. i hope she goes by tomorrow or I will have to call the Vet again. I cut back and her Dry food and am giving her more Can Food. She is on C/D and has been for over a year and a half. Will the Lax'Aire help her? I just started her on it.

The one time Wally seemed constipated, I gave him some Petromalt (same type of product as LaxAire). If I recall correctly, it took about 24 hrs to work.

for Coco

Thanks,
I hope it will help her.

I've tried Lax'Aire but it didn't work for Buster. He was very chronically constipated and needed stronger medicine though to get his BMs going.

I do not think it works to well for Coco. She went last night but had tried to go for 3 days before that. I wonder if the C/D has anything to do with the Constipation? I gave her more canned C/D.
