Well,Sister I thank you for that...we are almost SURE it is poison of some type....but the weird thing is that the other 2 dogs are fine.....she can't get into the garbage, or anything else. Almost down to somebody tossing something over the fence....and it seems they 'can't do' a tox screen on a dog.....labs are backed up with human stuff. NO flea bath, flea collar, etc...I won't DO flea collars. No bath for at least 6 mos....
