Poor Dixie I am so sorry to hear she is hurting so much and the swelling has come back.

I am sure that the vet has already thought of this but what came in my mind is that a grass seed had got in there, especially as it begins between the toes. From what I have read, and seen once on tv, they can go really deep and sometimes can be very difficult to detect but it does show very similar effects to Dixie`s.

I hope the two antibiotics do the trick and she begins to get better very soon.

Keeping her in my prayers.
