What is this sensitive white bump on my dog's back? Does he need a vet?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Male | 10 years and 5 months old | 6 lbs

My dog, Charlie, has an unusual bumb on his back. Almost like a large white mole. It appears he is sensitive around the area but not to the point where it generally hurts him. What is the bumb and how can I help him? Should I put some ointment on him? Does he need to see the vet?

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Charlie 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.

    This lump/growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infection or benign or malignant type of tumors.

    Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. What you are describing and based on the picture you have provided, this looks to be an infected mass or pustule from a skin infection. I would not worry about getting Tilly to an emergency vet clinic. I would recommend using a solution of betadine and saline mixed together to give a light brown color and use this to cleanse the area to disinfect it and clean it. If there are multiple pustules or bumps such as the one you have already described or this bump increases in size or continues to ooze pus, I would recommend having a veterinarian examine Tilly for further diagnostics and treatment recommendations. I hope this helps! Please let me know if you have any other questions or concerns.

I was wondering if you had any ideas on this white raised bump that appeared on my dogs back today. Seems to maybe have some pus too?

Just noticed this bump on my dogs back. It looks like a human wart? It is hard and small and white/skin color.
Yes, this does look like it could be a benign growth but unfortunately I cannot make a definitive diagnosis from a picture. 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 Charley's vet a call in the morning to make her an appointment. I hope this helps!

This bumps appeared on my dog. The one on his neck is a hard bump. The excess on the neck is like a soft patch. His collar is pretty loose and hes been in his bed from 1030am to around 6pm. I am not sure what to do as he seems totally fine otherwise.

Just noticed my dog has a red lump on his neck. It wasn’t like this yesterday. I did feel a bump when I was petting him a few days ago but today I noticed this red bump. Not sure if I should bring him to a vet or not.
I see what you mean about the red lump on Charlie's neck. It could be a cyst, a benign growth, or potentially a malignant growth if he's an older 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 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 in the morning to make him an appointment. Best of luck.

I have a senior Chihuahua about two weeks ago I found a growth on his right shoulder. It doesn't seem to be bothering him I don't know if it's a tumor or a cyst and I am really worried about him
In a senior dog, there is always a chance a lump 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. I would take Charlie into a vet on Monday. Best of luck.

I just discovered this bump on my dogs upper tummy. She doesn’t move when I touch it so I’m assuming it doesn’t hurt. I just have no idea what it could be.
