If she's chewing on her feet & developing sores from that it could be an allergy. I found this great site yesterday as my poor little boy started doing this. His dad is taking him to the vet today to get him checked out & determine what kind of allergy (food or environment).
Check it out.
For sure that is a "lick granuloma"… could be nervous habit or it could have just started as a bite or little itch.. that she kept working at and working at until it is what it is now... I too would suggest a Vet visit....
But if a nervous habit, again would have to ask what her daily routine is like?
sleep, play, stay outside n sleep for an hour than walk around the block twice, sleep again, then i play with her for about5 more hours, then its good night
Have you notice any time that she seems uneasy or stressed? Did you notice any bites she might have gotten from bugs or spiders? Especially if she is outside? I believe that you need to take her to a Vet to get these healed up… and it could very well be bug bites that she was itching and now is just "worrying" them to big open sores...
we dont have any red ants in the area that we chain her up in. but there are some around my garden which is way in the back yard. but i do take her to this pond in my neighborhood where there are lots of bugs
I would take her to the Vet… these will not go away by themselves
