My dog has a white, growing lump on his nose. What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 7 years old | 30 lbs

My Chihuahua Beagle, Guster, is 7 years old dog with a growth on his nose. I first noticed it two weeks ago, and it has grown slowly over that time period. His nose is wet (the growth is not), and it is white in color and the size of a piece of corn. He is not is distress either.

I see what you mean about the growth on Guster's nose. This could simply be a benign growth, but it could be malignant. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call to make him an appointment. I hope this helps!

Is this bump on my dog’s nose a concern?
It looks like this lump could simply be a benign tumor, but that's impossible to say without seeing the dog in person. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I'd give your dog's vet a call to set up an appointment for sometime this week. I hope this helps!

My dog has developed a lump on his nose back in October but has since got bigger it's o the outer of his nose he is breathing through his nose as I've checked with a mirror
The lump on his nose needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Punky to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

Can you tell me what this growth is on my dogs nose? He's UTD on his vaccinations and is 3 years old. It doesn't seem to hurt him but it has grown in size. It doesn't feel like there's fluid in it.
Thank you for submitting your question regarding Milo. I recommend that he sees his veterinarian. He will need a procedure known as a fine needle aspirate. The veterinarian will use a small needle to take a sample from the bump. The cells will be evaluated under the microscope to determine the type of mass. A common growth is a benign mass called a histiocytoma. It is not usually a problem and will go away within several months. A mast cell tumor, on the other hand, can look similar, but is a cancerous growth. The cells need to be evaluated determine if treatment is needed. I hope this information helps.

Hi, so I'm really concerned with my brothers dog, about a week ago he had a very sore looking spot next to his nose, and now its grown quite a bit
Thanks for using Boop by Petco! This could be a benign or malignant growth. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!

My dog has a large lump on his snout right behind his nose. It seems to be very tender as he always makes a sneezing sound when I touch it. Any idea what it might be and do I need to get him seen immediately?
This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors (unlikely given his age).

Hello my dog has a bump just behind her nose it's small but seems to bother her then you touch it or go near it
This bump on Missy could be a cyst, a benign tumor, or a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Missy seen by the vet today or tomorrow to have the lump examined and diagnosed to it can be treated as needed.

I am concerned about the sore on my dogs nose.
Thank you for submitting your question regarding Chloe. I recommend that she sees her veterinarian as she appears to have a mass on her nose. She will likely need a procedure known as a fine needle aspirate to diagnose the mass. There is a benign growth known as a histiocytoma that is common in young dogs. Unfortunately, it has the same outward appearance as a cancerous growth called a mast cell tumor. The sooner a diagnosis is made, then a treatment plan can be formulated. I hope this information helps!

Small white bump on my dogs nose has gotten larger in the last two weeks. It just appeared about 3 weeks ago. It does not seem to hurt him, but I am not sure what it is. He is a Husky/great Pyranees mix, 1.5 years old
Since the growth is on the nose, it would be best to bring Quinn into your vet for care. Tumors, fungal infections, abrasions, burns, etc can all cause signs like you are seeing, and since some are more serious issues, should be seen and treated, especially if the area is growing rapidly in size. Your vet can take a scraping or biopsy from the area to check under a microscope and see what is going on.

My 9 year old springer spaniel has a small round, soft, black lump / wart below his nose that he's had about 3 months but has recently started growing. Any ideas? He's fine in himself
This lump on Harry could be a benign tumor or it could be a malignant tumor. Unfortunately, malignant tumors are always a possibility in a senior dog. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Harry seen by a vet in the morning to have the lump examined and diagnosed so it can be treated.

My dog has a large raised bump on his snout. It came out if nowhere and started as a small bump. It's been there about 2 weeks and hasn't gone away. He's behavior is normal. Still very hyper and active. But it is starting to worry me that it's not he
this lump/bump/growth should be ideally examined by your local vet to have a diagnosis established. Your vet may want to perform an FNA (fine needle aspiration) or a biopsy to sample the bump and determine its underlying nature. Differentials would include skin cysts, infections, benign or more malignant type of tumors (unlikely given the age).
