My puppy has a white bump on his lip. Should I worry or see a vet?

No need to worry too much yet. In such a young dog it is highly improbable that anything too terrible is wrong. In all honestly, it is very hard to make a diagnosis of dermatologic issues without actually feel the lesion, and / or collecting some diagnostic samples. At first glance, they look like eosinophilic plaques (otherwise known as rodent ulcers), which are actually much more commonly seen in cats. Since you are seeing these lesions on both sides of the mouth, it's also possible that this is something anomalous but normal in your dog. Another possibility is that your pup could have bit onto something that cause some irritation, and it is now causing something wrong symmetrically. If the areas aren't getting large and are not bothering your dog, my advise would be to leave things alone for the time being to see if there is any change. However, it wouldn't be wrong to take your dog to the vet now to have him checked over. Hope this makes sense!

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.

Based on the appearance of this lesion and Baldrick's young age, I would guess that it's most likely either an epulis (https://www.petcoach.co/article/epulis-a-common-oral-tumor/) or an oral papilloma. The challenge with any lump or bump is that the only surefire way to diagnose the issue is with a biopsy. Both of these lesions are benign, but oral papillomas are contagious to other dog due to their viral origin and epulides can grow significantly if left in place. While this issue certainly isn't an emergency by any stretch of the imagination, I still think it's worth taking Baldrick to his vet in the coming weeks to have it checked out. I hope that everything goes well!

I'm glad to hear that Colette does not seem to be bothered by this mass! The only way to definitively determine the type of mass present (benign or malignant) is through a fine needle aspirate and/or biopsy. Without determining the type of mass, I can't say if this is something that should be monitored for changes or if it should be surgically removed. Since it has noticeably grown in just the past few days, your safest bet is to take her to the vet to have the mass evaluated. I hope that all goes well!

This looks to be a histiocytoma. I don't think he needs a vet visit just yet. Often these will go away on their own. I would only be worried if it doesn't go away in a month or so OR if it grows larger OR if it starts to bother him. Please read this information: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952066 Of course, if you are worried, a vet visit is never a bad idea.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Judging from the pictures, it appear that Butta has a small pimple like mass on the muzzle. This could be a pimple, insect bite or viral papilloma. I would recommend keeping a close eye on this and if it worsens, I would take him in to be examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

The photo is a little fuzzy so its hard to say. It may be an oral papilloma, which is due to canine papillomavirus. Typically these resolve on their own, but many more may pop up over the next few weeks on his lips and in his mouth. It could also be an inflamed hair follicle or a skin infection. If its not resolving over the next few days to weeks, or if it seems to be getting worse or causing him discomfort, please take him to your vet to be evaluated. Here is an article on canine papilloma virus. http://www.pethealthnetwork.com/dog-health/dog-diseases-conditions-a-z/oral-papilloma-virus-dogs Thanks for asking PetCoach!
