Poor Mini! I see that she isn't spayed, and I would be very concerned that these two bumps around her nipples are mammary tumors. Dogs who are not spayed are prone to developing mammary tumors, and 50% of those tumors are malignant. They will be painful as well, causing her to not want to eat and possibly vomit. The best thing to do is have her seen by a vet as soon as possible. The vet will need to do biopsy of these bumps to diagnose if they are malignant or benign. Should they be malignant, they will need to be removed surgically, and her local lymph nodes will need to be checked to see if there has been localized spread of the cancer. Please take her into a vet.

With mammary tumors in dogs, 50% of them are malignant. You need to have Daisy Duke seen by a vet and get it diagnosed. If they are malignant, they should be removed surgically. I'd have her seen by a vet tomorrow.

If it is a lump I highly recommend taking her to a veterinarian. If it is a lump it can be a mammary mass and there can be a 50% chance of malignancy with them. If this is the case, chest xrays and removal and biopsy are necessary. Thank you for using Petco Pet Education Center, formerly Petcoach.
