My 3-3/4 lb. chihuahua had surgery on Thursday for pyometra. The uterus, fallopian tubes and ovaries were all removed. The case was quite bad, even though she hadn't shown any signs of illness until this Tuesday (2 days prior to surgery). She is now recovering, but I'm a little worried that she seems to have a bit of swelling in the tummy area, more so on the right side. Post-surgery, her belly did look very sunken.
Here are links to photos of how she looks now. The area I'm concerned about is around her bottom two nipples, especially the right nipple (left side of photos).
Is swelling normal from this surgery, or should I be worried?
Thanks for any information.
