This may be the start of a small skin growth or it can be a small scar tissue from a scrap or wound. You can monitor the area for any changes. If it gets larger or starts to bother him then I would have it checked by your vet.

Since it hasn't grown and has been there for some time, it could just be a cyst or benign growth. The best thing is to have your vet do a needle aspirate to determine the exact cause. Once diagnosed, your vet can determine if treatment is needed.

Since it has been there for 3-4 weeks now it is unlikely to go away on its own. Since it is getting larger it is best to get it checked by a vet to see what it is. It has potential to be an infection, an allergy/reacion, ring worm or a growth.

My dog has a small bump on his leg. Could it be from an old scab?

This looks like a small growth in the skin. It could be a scar or reaction from previous injury or it may be a tumour. Tumours van be benign or cancerous. I would not panic overly about this as it doesnt look too nasty, keep an eye and get it checked if it is changing quickly. If you ate worried you could have it tested to know what it is exactly.

What's this tiny, painless bump on my dog's back leg near his hip?

This lump under Behr's skin is most likely something benign like a cyst or lipoma, however there is a small chance it could be something cancerous. At such a young age cancer is unlikely but not impossible. If the growth doesn't go away within a few days or it gets larger it would be a good idea to have Behr examined by a veterinarian. If necessary a small needle aspirate can be taken from the lump and looked at under the microscope to determine if it should be removed surgically. Thanks for using Petco Pet Education Center, formerly Petcoach and I hope the small lump ends up being a benign growth!

My dog has a hard bump on his leg. Why is he scratching and licking?

I can see the round, raised bump you are referring to. This can be a small growth, allergic reaction, bug bite, or a sign of a skin infection. I recommend having Kane seen by a vet, as this is clearly making him uncomfortable. Your vet can take a small sample with a small needle to determine exactly what is going on and rule out the conditions above. In the meantime, you can get Kane an E-collar or "cone" to prevent him from licking the area and making it worse.

What's a recurring red bump on my dog's leg that he keeps licking?

I would recommend that Spoko have this bump checked out. It could be anything from a skin tag or wart that gets irritated because he licks, to an infection or foreign body (something stuck under the skin), to a small tumor. After examination, a vet may decide to collect a small sample of cells to look at under a microscope to hopefully determine the cause so that an appropriate treatment plan can be created. While you wait for his appointment, try to keep Spoko from licking the bump; he may need to wear an e-collar/cone to prevent this.

My dog has a clear, blister-like bump on its leg. What should I do?

I can see the small, raised, slightly red hairless lump on Hazel's paw in the photo. This may be a bug bite, localized skin infection, or a mass (which is less likely in younger dogs). I recommend having the area examined by a vet to determine the underlying cause and begin the appropriate treatment. In the meantime, you can get Hazel an E-collar or "cone" to prevent her licking the area and causing further trauma and irritation.

My 8-month-old lab has a red bump on his leg. Could it be a tumor?

Tucker likely has a localized infection or perhaps a skin tumor. The good news is that its most likely benign. Rarely, young dogs can get a malignant tumor called a mast cell tumor so I would recommend to have the area examined by a veterinarian to be sure. The doctor may recommend to take a small sample of cells to make sure its nothing to be concerned about.

My Chocolate Lab has a growth on his hind leg. What could it be?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
