What's this red bump on my senior dog's head with hair loss?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Female | spayed | 9 years and 10 months old | 68 lbs

Hello. I have a 10 year old yellow lab. She's very healthy, active and ideal weight. She's recently developed a bump on her head - it's a bit red and the hair around it has fallen out. It also appears that right at the base of the bump, it got infected and had some pus and bled. I've cleaned it and that part has gone away but not the bump. Can i send you a picture? I'm going through a divorce and really don't have the extra $250 to go to a vet if i can avoid it.

I am sorry that Aspen has developed a bump or lump on her skin. Thank you for providing pictures. From the pictures you have sent the "bump" appears to be a skin growth. There are several types off masses that can grow in the skin of dogs such as cysts, lipomas, and even cancers. Some are benign and some are malignant, so careful observation is important, as well as having a vet examine it if you are concerned. Since you only noticed the lump recently, I would continue to monitor it for growth, ulceration, changes in texture or color. Measure the mass with a ruler so you can compare its growth in a couple weeks time. Rapidly growing masses are more concerning. You can also try applying a cool compress and cleaning with warm salt water once daily if it needs it. If you notice any changes or rapid growth either take Aspen in for a vet appointment or post another question here on the forum. I hope that this answer was helpful and more importantly that Aspen feels better soon. Warmest regards to you both.
