I just read this as I have b een very busy and not online for a couple of days. Lots of love and prayers for Sparky and I do hopr he will be fine after you see the vet. I have heart problems like Sparky and couldnt take Lasix after a while; My doctor changed me to Hydroclorothiazide and even after several years now I find it very effective (and cheap) Lots of love and Pets to both doggies!
