Is my 10-week-old puppy's pink lip mark from teething or chewing?

It may just be a little boil that formed due to a mild infection or even trauma from his tooth. If it isn't bothering him then I would just keep an eye on it for the next 2-7 days to see if it resolves on its own. Most of the time these do. If it doesn't then have your vet take a look to see if treatment is needed.

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any scratching.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. From the photo, this area does not looking concerning to me. However, if you are concerned and/or if this area bothers your pet, I recommend having him evaluated by your veterinarian. Your vet can examine this area and determine if it is a normal variation in his skin, or if it could possibly be a mass. You can also monitor this area for ~1 week to see if it changes in size/shape or feel. I hope this is helpful!

That lesion looks very inflamed. It’s possible it’s a reaction to something he chewed on but an infection is also possible. I recommend to have him examined by his veterinarian to rule out something more severe like a tooth root abscess. He may also get medication to help heal the lesion. Best of luck.

It looks like depigmentation. It is nothing to worry about and also nothing you can do about. It may stay like this, it may progress and more skin on Hazel's chin will become pink rather than dark/black.

Poor guy. Yes this does seem to be a localized reaction and it could be to just about anything that has been newly introduced or even something Mork got into that he is having an allergic reaction to. I wouldn’t suspect this is caused by brushing his teeth too hard because this is his lip area that looks irritated. It’s best to visit your vet for some medication to help combat this reaction, especially if this area is bothering him and not improving on its own within a few days. I hope that Morks skin clears up soon! Best wishes and take care.

Hello, thank you for your question about Bear. Based on Bear's relatively young age and the photo that you have provided I would be suspicious that Bear is experiencing a mild bacterial or viral infection in this area. Puppies are often more susceptible to viruses such as the papilloma virus more than adult dogs, this virus typically forms cauliflower like growths in/around the mouth, but certain forms can be more mild and not lead to these signs. It is possible that Bear has a bacterial infection, these are usually fairly benign and self limiting. Another possibility is that Bear is experiencing sensitivity or an allergy to something in his environment leading to this lesion. Some dogs are very sensitive to certain types of food bowls or toys, and can develop these lesion secondary to this. I would recommend having Bear evaluated by your veterinarian so that they can examine the lesion and Bear's mouth. They can discuss the need for additional diagnostics such as an impression smear or gentle sampling of the area. Depending on these findings they can then make recommendations for necessary treatments such as antibiotics. Hope this helps, good luck!
