My dog has a pink, hard lump on her belly with a scab. Is it cancer?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | spayed | 3 years and 11 months old | 40 lbs

Piglet, 3.5yo, pugxlab, i noticed last week that she had a pink lump on her belly, it is hard and not attatched to her ribs or anything, i haven’t been home a lot since then but yesterday i notice it had gotten a scab on it and has gone a weird colour. Do you think it’s benign or should i go get tests? the shape or size hasn’t increased, i think it’s decreased in size very slightly

Hopefully it's nothing but any red, raised mass is concerning for a skin cancer called Mast Cell Tumor. Many other lesions though can look this way but I think it's always best to play it safe and have it tested. Aspirations of a mass are generally quick and easy and most pets tolerate them well. I hope this helps and please feel free to post any additional questions.
