My dog's lump sample was brown fluid. Is this serious or normal?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. 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 night!

This is likely just a cyst or possibly a localized infection. Since it isn't changing and your dog doesn't seem to be too worried about it, I wouldn't be too concerned. I would just wait for your vet to call you. If you haven't heard from them in a few days, I would call them to double check on the results. I hope this helps!

Typically a lipoma does not get any fluid. It usually produces fat cells that resemble oil droplets. if you got fluid and blood then I would have your vet check a sample to see what cells are there to find out what it was

The fact that this has been there for so long, and the straw color to the fluid suggests that this is likely just a cyst. They tend to fill back up after being drained, but are usually benign. You wouldn't be able to drain spinal fluid from your pets skin. You can have the cyst surgically removed to resolve this for good or keep having it drained by your vet, since they can use sterile methods to prevent it from getting infected. If the discharge is ever reddish brown in color, then it is likely an abscess and requires antibiotics to resolve. I hope that Cocoa continues to do well. Best wishes and take care.

It appears that everything in that bloodwork is within normal range. It is not unusually for bloodwork to be normal when there is a lump. The best way to diagnose the type of lump is a needle aspirate or a biopsy. A needle aspirate is a simple procedure that your vet can do to determine if it should be removed. I’m not sure if the lump is getting bigger or changing but, if it is, then she should definitely be examined soon. If it turns out to be a benign lump then you may be able to just monitor it without removing at this time.

It could be that Kuba had a cyst, which is why it was removed (they can grow back even after being drained). This new lump could be another cyst, a lipoma (benign fatty tumor), a benign tumor, or a malignant tumor. Because I can't see him in person, I can't say for certain what this lump is, and I would follow your vet's recommendation to watch it for now. Wait and see if it grows bigger, and if it does, then I would talk to the vet about getting it removed.
