Hi Maria-
It's highly unlikely it has spread in 2 weeks; however, it is important that you get her to a new vet the first of the week so this can be taken care of. Don't ignore it as the only thing it will do is get worse and you don't want Susi to suffer! Please pick a new vet tomorrow and take her in. If you call your old vet's number, they should have left a forwarding number or contact information. It would be highly unusual for a vet to pack up a practice and leave town without assigning their practice to someone else. If they did, I would start from scratch and give the new vet as much information as you can. Good luck and let me know if I can help further.

Your veterinarian should ALWAYS be consulted first and foremost when your pet's welfare is at stake.
