hello both of you, (btw mutgirl my dog is still limping-10 weeks), sorry raider i'll get back to subject. when i did the pads, i bought a box and 4 samples. same result as you have, every day the same tar. raider you said you want to get it tested, the 1st time you mentioned it i was going to write you may be to test the powder inside before use. i did not because i do not want people to think i am negative. when i read the post from kelly, who did it for 2 months and still the same tar, i was glad i did not spend more money. so i will be following your stories, johanna
