Could be that the dog has OCD, in which case, keep her from chewing on it even if it means physically restraining her head with a head cone. Could be that the nipple was already causing her discomfort and she started chewing on it to alleviate that discomfort. Take her to a vet.
i really dont know thats wut im trying to figure out
Probably not--but keep in mind you're not supposed to "hoover" it--nipples are a tender area.
No
nope
no you don't!!!! dont be a pilock!!!!
See your doctor, as there should not be any bleeding.
Yes the nipple will get loose, as you must remember the baby when sucking milk must have a soft nipple
The phrasing of the question sounds like it was written by an immature adolescent, but as nipple sucking constitutes sexual foreplay, it could be illegal if you are a legal adult.
No, you cannot get any STDs from sucking on a person's nipple. However, you can get STD's through breast milk.
sucking reflex
Absolutely not. Only puberty can do that or surgery.
Rooting and sucking reflexes
it will probably feel weird at first. but it is just a sucking sensation on your nipple.
