A. If the growths are continuing to change in size or are becoming discolored, have discharge or are bothersome to your dog it is best to bring her back into the vet. It is possible the growths could be worsening and may need removal, or your dog may need increased palliative care to keep her comfortable. Be sure to alert your vet to the changes you have seen as well as how quickly it progressed so it can be monitored.
