Why does my 8-month-old dog have worsening skin bumps and spots?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 8 months and 6 days old | 60 lbs

My aunt left on a cruise yesterday. I am watching her female 8 month old dog (she is large) a few weeks ago I noticed little bumps on her inside ear area, asked about it but she said it was garden thorns? I also noticed some little marks on her undercarriage. Today was my first full day watching her letting her out etc. and i noticed the undercarriage spots look worse. The pup is not acting stressed or scratching. But I don’t like how it looks. Side note she is in heat.

Hello. This looks pretty typical for an allergic dermatitis that has lead to a skin infection. Ideally, this should be addressed by your veterinarian. They can discuss possible causes (food allergy, contact allergy, flea allergy, etc) and prescribe medications which may include antibiotics for the raised lesions and allergy therapies.
