I just came home and found Dixie's paw twice the size it was this morning when I left for work. I called the vet again and they want to see her back at 5:45 Eastern time. I think there must be something embedded in her foot and it looks like now it may be infected. I have used a magnifying glass and can't see anything. Please say a pray that the vet can see what is going on this time. It breaks my heart to have her hurting. Thanks.
