Why does my dog have a soft, squishy lump on her head after a fight?

There can be several causes of a lump like this, including a seroma or hematoma from hitting her head on something, an abscess or infection, an enlarged lymph node or salivary gland (if the lump is lower toward the jaw), a tumor or cyst, among a few others. Since some of these issues need veterinary care to resolve, I would recommend that Fifi get checked out by a vet. After physical examination, the vet may recommend a needle aspirate and microscopic exam or x-rays to see what the cause of the lump could be.

Hello, sorry to hear about Sammi. It’s 50/50 chance of telling really what it is based on the description. This would fit similarly with a cyst or a mast cell tumor. Other sabaceous adenomas can also look as such. The base of it being red does concern me a bit more for a mast cell tumor. The best way to differentiate these is by obtaining a fine needle aspirate if the mass to rule out a mast cell tumor. If so, then you can be less concern and discusss with your primary care veterinarian if removal is warranted. Hope this helps and best of luck.

Well that's pretty odd! It could be a bug bug, a minor trauma outside while running around (so basically a big blood blister), or even the start of hives from an allergic reaction (but it would be an usual hive). A mass wouldn't show up so quickly. I would recommend monitoring Reggie closely for the next few hours to make sure it's not getting worse. If no changes, call your vet in the morning to schedule an appointment, but if keeps getting bigger or you notice any more changes in Reggie, head to an emergency clinic.

You are correct that this lump could be a fatty tumor, but given that he was attacked by a dog last week, it could be an abscess. Another possibility is a cyst. Given his age, it's quite unlikely Bugs has a malignant tumor. It's a good idea to have him seen by a vet :-)

This could be a seroma from an injury, a cyst, abscess or a tumor. Cysts and abscesses need to be drained by a vet. If your vet suspects a tumor, he will do a fine needle aspirate to determine whether it is a harmless lipoma, which does not need to be removed unless it is ulcerating or bothers the dog due to its location or size, or another tumor that needs to be removed. Please make an appointment with your veterinarian for an exam of the mass.

If it recently got bigger than you should have a vet take a look at the lump to determine the cause. She could have an infection, cyst, or a mass and your vet can do a needle aspirate to help diagnose and then determine if any treatment is needed.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach! This appears to be a fluid filled cyst from the looks of it. These can come and go at times. Typically there is no concern with these other than the fact that they are unsightly for some pet owners. This is something that could be removed under sedation if you would like it removed.
