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!

Thank you for providing a picture of Joe's bump! It could simply be a wart or another type of benign tumor, but it could also be a malignant tumor. It's a good idea to get any bump that has been present for while checked out by a 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 bump 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 Joe seen by the vet in the next couple of days so the bump can be diagnosed and treated as needed. I hope this helps!

Any lumps/bumps that you notice on your dog should be checked out by your vet. Lumps are usually one of these things:

* abscess
* cyst
* tumor
* wart

There is no way I can tell you what it is just by looking at a photo but I have a suspicion it is a histiocytoma (benign tumor) or a cyst. The product you are using will not hurt but it will not make this go away. It is not urgent but you should get her to your vet for an exam in the next few days.

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

My dog has small bumps on his back with black hairs. What are they?

These bumps on Snoopy could be warts or another type of benign tumor. There is a chance they could be malignant, but it's not very likely in a dog his age. Any suspicious bumps 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 bump 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 Snoopy seen by a vet in the next few days to have these bumps examined and diagnosed so they can be treated as needed.

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.

What's this rough lump on my 10-year-old dog? Is it a skin tag?

Yes, this may just be a benign growth like a skin tag, but I cannot make a definitive diagnosis without seeing him 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.

My dog has a bump after grooming. Is it a wart or just a skin tag?

This looks like a mass. It looks quite benign such as a wart or skin tag, however it is impossible to know for sure without testing the lump. You could have the lump tested/removed or simply monitor it for changes. I wouldn't be overly concerned about it.

My dog has a small brown scaly lump. Could it be a wart or cancer?

Thanks for sending the picture! It appears to be a wart like growth with a small scab on top. These are common in small breed dogs. If it grows or changes rapidly, then I would still have her veterinarian check it out. Otherwise I do not suspect it will be a problem for her. You can try to clean the scab off for her. Good luck!

My dog has a back lump that changed shape and bled. Should I worry?

I agree it does look like a wart, but it is concerning it has changed shape and is now bleeding. I do think it should be checked out by a 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 Peanut's vet a call to make him an appointment.
