That sounds terrible. I hope things work out okay.
I just read about something terrible in the Thailand news:

Sometimes the problem is that they run out and don't get replaced!
That's why i got some from http://www.dogwastebags.com.au/
Almost 700 bags for 30 bucks, delivered.
They are the also the degradable kind of dog waste bags.
This site sell them
http://www.dogwastebags.com.au/
They deliver all over australia.
And I'm sure that these are the same bags that I've seen in parks around my home.
