My 7 month old pitbull has these three bumps on his lip. One is like inside his mouth and the other two are outside. They feel a little hard and they don't seem to hurt him. What is this? Will it go away on its own? Is this normal?

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.

    These could be papillomas (warts). Your veterinarian can confirm this with a physical exam. Papillomas, which are viral in nature, typically resolve on their own in weeks to months. They can be spread to other dogs, so limit or prevent contact as much as possible.

Hello, I recently noticed my dog has bumps around her mouth and I’m curious on to what they are, why they are there, and what I need to do for her.. I’ll attach photos below
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.

white bumps inside dogs mothb
Although I cannot say with 100% certainty without a hands-on exam, these bumps look like mouth warts or papillomas. A common cause in young and otherwise healthy dogs is a virus. This would be more likely if your pet has contact with other dogs such as at a dog park, doggy daycare, etc. If they are caused by a virus, there has likely been mouth to mouth contact with another dog, or the saliva of another dog on a toy, stick, food bowl, etc. Most cases of viral papillomas are self limiting, eventually resolve on their own - but are highly contagious. I would recommend that you have your vet examine her to make sure this is actually what ha going on.

Hello, my dog has had bumps on her lips since Thursday. They look like warts or a virus. Do you know what this is? Thank you.
Thank you for contacting Boop by Petco 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!

I discovered this on the inside of my dogs cheeks and one on his lips. He is a English cream golden Retriever 11 months old. It’s a white hard smooth looking bumps. It doesn’t seem to be hurting or bothering him. I don’t know if this is normal or not
These look like benign papillomas (warts). They are very common in young dogs and generally don't cause pain but can be severe in some cases. They are also very common in young dogs and are caused by a virus. They are self-limiting which means they generally go away on their own within 1-2 months without any specific treatment. Sometimes they do require cryotherapy for removal in those severe cases, which in this case it doesn't appear to be the case.

Take care.

Hello, Yesterday I was playing with my dog who is 8 months old. I noticed that he has these little white bumps all in his mouth. I have a picture of 2 if the on one side but the other side he wouldn’t let me get. He has around 10 or so all in his mo
This is Papillomavirus. This is more common in young dogs and the majority of the time you just have to let the virus work itself out of the system. If they start getting really bad we can try to treat. I wouldn't be too concerned about your older dogs especially if you were just playing with the puppy. It is very contagious but when dogs have a good immune system it is harder to get the virus, although not impossible. Thank you for using Boop by Petco

My dog was playing all weekend with a new dog friend! He's got a lump that is just on his upper lip ( snout area) I'm assuming it's just from them playing because there is a clear cut directly in the center. What may this be from?
Certainly it could be due to play, and dogs like to play with their mouths, especially when they're young and they're trying to figure out appropriate play methods with other dogs. If it's a wart-like growth, it may be a canine papilloma. These often show up on the mouths and feet of young dogs, and they are contagious between dogs. You can go to Google and look up images of these, so that you can see if this is what you're seeing on your dog. Papillomas usually go away on their own in about 2 weeks. If the lesion is still there at that point, I would get it checked by your vet.

My dog has white growths in his mouth. The big one has been getting bigger over time. The small one is new and there’s a second small one very close to it. What is it? Should I be worried?
This appears to be a papilloma virus wart. They are common in puppies. I suggest you leave it alone. It will probably go away by itself in a few weeks. If it doesn't you can take him to a vet for an exam. DO NOT apply anything to it.

hi, i noticed these raised bumps inside my 10month old Husky's mouth. He was playing roughly with other dogs yesterday. Could these be from the play or possibly from chew toys?
Hi, thanks for using Boop by Petco! 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

Our Bentley has what looks like two warts near his mouth. They are small, white with little black dots. One is near his whiskers and the other on his gum. My inclination is that it isn't the papilloma virus because he has had these growths for approx
There are a few differentials for the masses on Bentley's mouth. Papilloma virus, infected hair follicles, inflamed skin pores are the most likely. Papilloma virus (warts) generally affects younger dogs so if the other dog is older, it is most likely immune to the virus. Warts also typically take 2-3 months to resolve. These lesions typically resolve on their own and don't requite treatment. Hair follicle and pore issues typically look red and inflamed, plus they would generally not show up on the gums. Sometimes these do require treatment. When in doubt, take Bentley to see his doctor to have it looked at. Hope this helps.
