Hi Jackieboy, I, too, read your posts, and I think the others gave you good advice. Apparently, none of them have had the same experience as you are having - just as the problem I am having with my dog's sneezing at certain times of the day, yours is an unusual problem. When the poster said you could save money by collecting the urine in a baggie, I'm almost positive he/she didn't mean to tell you that you were trying to avoid going to the vet.
You had already said you panned to see the vet. I think the whole thing is just a misunderstanding. Good luck!
