Why is my 5-month-old puppy's skin rash spreading and what can I do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 4 months and 16 days old | 6.3 lbs

My 5 month old puppy has an unusual rash on his back, forehead, face and now his neck. It was just a small half dollar size dry pimply patch on his back but has since spread now down his back, under his neck and on his face. It doesn’t seem to bother him and I say this because he’s not scratching at it. The rash is more red and blotchy under his neck. What could be causing his skin ailment and what can we do to help him rid whatever it is?

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. I suspect it could be bacterial skin infection or allergic skin problem. Please, take your Charlie to your local vets for an appointment as he will likely need treatment with skin ointment with antibiotic and/or anti-inflammatory agent.
