Should I worry about a growing black spot on my dog's stomach?

Hi, sometimes dogs can get blood blisters usually on their underside. If it's not bothering her, leave it alone. Iy may go away on its own or stay there. If you think she's bothered by it, she should see a vet about getting it removed. But it doesn't mean anything bad is going on. Good luck, I hope this helps!

This looks like it could be a cyst or a skin tumor like a hemangioma. I find that once a skin growth ruptures it tends to happen again, so I would definitely recommend making an appointment to see your veterinarian. They will probably recommend surgically removing this growth.

Based on the pictures, it does not look like a tick. It looks like a skin mass. Have your vet take a look at him to determine exactly what it is. Your vet may want to aspirate or biopsy to diagnose.

It is hard to tell from the picture what these could be. Sometimes growths of the oil glands in the skin can appear this way. Infection can also be black and crusty. Melanomas can also appear as black growths on the skin. I would recommend that you take her to see your veterinarian so they can take a sample to diagnose it so that you know what it is and what needs to be done about it.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely some local irritation. This may be due to allergies for example. It may be an allergy to something specific in the environment or something else like fleas or food. This may go away on its own if it is something minor. However, if this continues, I recommend you have her evaluated by a veterinarian for further assessment and treatment. Best of luck!

Poor Baby! Due to its dark color and it's changing nature, I would have your vet take a look at it. It could just be a benign blood cyst and nothing to worry about, but it could also be a malignant tumor that needs to be safe. If your vet isn't sure, I would have it surgically removed and sent to the lab for testing to be on the safe side. I hope this helps!

This mass certainly looks concerning. As it is growing, there is a suspicion that it is likely a malignant mass. I suggest you schedule an appointment with your veterinarian for an exam and a so-called Fine Needle Aspiration (FNA) where your veterinarian takes a small amount of tissue from the mass with a fine needle. This is usually not painful and will help determine the type of mass and whether it needs to be removed surgically.
