sorry that i got worried with this whole nipple thing.....
well friends, i did what many of you told me, i cleaned/wet it and then peeled it off
to my surprise it was like a shell of an egg. it was nothing!

i was so relieved! it was just crusty material, like many said probably an infection of sorts....
**the reason i was worried was because i saw a hole when about to peel it; i now know that it was because most of Tiggy's nipples are recessed......most of her nipples do that pop out...unlike my Chestnut, who's nipples are 3-4 centimeters pronging out!
thanks again everyone,
i know i panicked a bit
but i get so worried over every little thing for my doggies
wish Tiggy luck in her surguery(next week) for Leggs Perthes and quick recovery, thanks so much everyone!
