Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Jojo. These could be canine oral papillomas, which are small benign tumors of the mouth causing by the papilloma virus. Without seeing her in person, I can't say for certain, so I would have them checked out by a vet. If they are canine oral papillomas, treatment is usually not needed unless they become infected or she develops a lot of growths. I hope this helps!

Given this lesion's location, appearance, and Hazel's young age, an oral papilloma is by far the most likely culprit. Unlike papillomas that occur on the skin, oral papillomas are spread in dogs as a virus. The good news is that oral papillomas usually go away on their own in several months without any treatment. However, it's best to keep Hazel away from other dogs at doggy daycare or dog parks until her lesions resolve. All of that said, it's absolutely reasonable to keep an eye on the lesion for a couple of months to see if it resolves. If the lesion grows or changes, if you notice more of them crop up, or if it doesn't go away in a couple of months, then I'd recommend taking Hazel to your vet for an exam to check things out.

I hope that everything goes well for Hazel!

Hi there and thank you for using pet coach to address your concern. If what you are seeing on the lip is indeed a papilloma, these will typically resolve on their own. They are typically not very painful and do not bother the dog most of the time. There are medications to try and help speed up the resolution of the papilloma virus infection, but if these very in their effectiveness at treating the papilloma virus. Most of the time these do not require treatment. I would monitor the bump for now and if it begins to worsen or many more begin to show up then I would have them examined by a veterinarian so that the most appropriate treatment can be recommended. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be happy to help you further.

My dog has bumps on her mouth. Are they warts? What should I do?

These look like juvenile warts (oral papilloma). Such warts are caused by a virus, they are self-limiting and and will go away by themselves eventually within a few months. They will need veterinary attention if they increase significantly in size or amount or start bleeding, get infected, or cause other problems.

My dog has a white bump on her lip. Is it a wart? What should I do?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Based on your picture and Rio's age it looks like a papilloma. It is virally induce and contagious. Most dogs get it from doggie day care or other close interactions with other dogs. Usually they spontaneously regress. Sometimes I'll crush them in the office and put the dog on a 10 day course of Azithrimycin.

Puppy has hard bumps on lip. Are they dog warts? Will they go away?

Hi. These growths look like papillomas or warts. Typically, these are caused by a virus that he may have contracted by coming in contact with another dog's saliva that had the contagious virus. This may have been through a shared food or water bowl, toy, or through playing. This virus usually runs it course and the warts fall off, but it can take weeks. Sometimes, your vet may have to surgically remove them. Your dog is contagious as long as the warts are present.

Should I worry about a small red blood filled bump on my dog's lip?

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!

My dog has a bump on his mouth. Could it be a wart? Is it serious?

Hi there and thank you for using Pet Coach! From the pictures you provided and knowing that Klaus is young, what you are seeing appears to be what we call a papilloma. These benign masses are caused by contact with the papilloma virus, usually picked up from another infected dog. The good news is that these masses typically resolve on their own and require no specific treatment. Sometimes these do not go away and need to be removed or are getting too large and become an eye sore or catch on objects and bleed. In these cases, sometimes we will prescribe an antibiotic such as Azithromycin which has been shown to reduce the size and even resolve some papillomas. Most of the time, however, these masses will turn gray or purple in color, shrink and then fall off. If you are concerned about the mass then I would get this examined by your vet. I hope this helps! Please let me know if you have any further questions or concerns. I am also available via phone or text consultation if needed.

My dog has growing bumps on her tongue and face. Are they contagious?

Hi there and thank you for using PetCoach to address your concern. What I am seeing in the photos appears to be what we call a papilloma. These are a result of the canine papilloma virus and it is likely that Georgia picked it up from another dog. It is possible that your other dog could get it but if your other dog is much older, it is less likely to happen. These bumps typically go away on their own but can take months to resolve. There are treatment options that may or may not work. Please follow the below link for more information on this viral infection. 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. http://www.veterinarypartner.com/Content.plx?A=465

My dog has bumps in his mouth. Are they contagious or serious?

Hi, thanks for using Petcoach! Thanks for the picture, it really helps in this case! Those bumps in his mouth are viral papillomas. They are very contagious from dog to dog. They take 1-2 months to incubate so I do not think they are from yesterdays play session. I would warn that dog's owner that their dog may get them. They are benign and will go away on their own. When I see a dog with them on appointment I crush a few of them to make them bleed and place the dog on azithromycin for 10 days. That tends to stimulate the dogs immune system quicker to help fight the viral infection. Blue should not play with other dogs until all the lesions are gone. I hope this helps and I wish Blue a speedy recovery! http://www.pethealthnetwork.com/dog-health/dog-diseases-conditions-a-z/oral-papilloma-virus-dogs
