Congrats on your new addition! The picture is a little blurry, but the area looks concerning. Did the breeder give any vaccinations? If so, she may have had a reaction to the vaccination if it was injected into the skin instead of under the skin. Another possibility would be that it is simply a skin reaction/infection from something else. I would recommend having your veterinarian examine the area to determine if it only involves the skin or if it involves any deeper tissue. They may need to take some samples to evaluate under the microscope to determine if the skin infection is bacterial, fungal or even parasitic (like mites). Then they will be able to determine the best treatment to resolve the area. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
