My dog has bleeding, sore bumps on her lip. Is it serious or acne?

Hi there my female dog who is Boxer/German Shepherd. She started with a bump on her lip but over the last two weeks she has gotten allot more and they bleed and look really sore. I don't know what has/is causing them or how to get rid of them. I can't afford a trip to the vet either unless it's something serious. I hope you can assist me in finding out what is bothering my sweet baby. Thank you so much for your time.

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Aurora is adorable! Even though these could represent cancerous nodules, it could likely be something like dog acne. The cause of this is usually exposure to perhaps a dirty water or food bowl so a good way to prevent exacerbation of this or to prevent it from happening is by making sure her water and food bowls are clean. Sometimes, this resolves on its own by keeping her food and water bowls clean. However, if it does not resolve on its own in the next week or so, have her evaluated by your veterinarian for therapy which may include steroids and a topical antibiotics and diagnostics if on further examination, it appears to be something other than simple acne. Good luck!
