My dog has a fluid lump on his head after surgery. Is it normal?

This is most likely a seroma which is just a fluid pocket. But a seroma can inhibit healing if it is too big. I would have your vet look at it so they can drain it. Your vet will be able to confirm that it is a seroma and that there isn’t any pus or infection involved. After it is drained you can put a warm compress on it for 10 minutes twice a day to help prevent the fluid from coming back. Sometimes it will return and need to be drained again. Also make sure you are keeping her confined as too much activity can also cause these to form post-op. I hope this helps!

The picture that attached looks like a fluid filled cyst (pocket of fluid). If so this is not concerning. Marley may scratch it and it could burst. Also not concerning but it may fill back up. The only way to cure a cyst is to surgically remove it. Discuss your options with your vet. Good luck and kisses to Marley!

Based on the picture it looks like Marley has a small cyst. Cyst will fill out with clear fluid but can also have different color fluid. Cyst are typically non cancerous and nothing to be concerned about. However you should never decide what a mass is based only on looks. Some cancerous masses can look like anything for example mast cells tumors. I would recommend taking Marley to a vet for an aspirate of the mass. The vet can look at the cells under a microscope and tell you what the cause it and if it should be surgically removed. hope that helps

Good on you for having Marley seen by a vet! Given that it's too small to remove at the moment, I would monitor the lump for now. If it gets bigger and stays bigger, then I would have him seen by a vet again. At that point, it may be able to be removed. Should the lump continue to swell and shrink and you are concerned about it, it's certainly ok to have Marley seen by another vet for a second opinion. I hope this helps :-)

It could be an infection, cysts, or a mass. Marley should be examined by a vet to determine the exact cause. Your vet can do a fine needle aspirate to determine if it needs to be treated. If it is just a benign lump, your vet may want to just monitor it for changes.

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.

Larger dogs or dogs that are playful after a procedure can develop a seroma at the incision site. These firm bumps under the skin at the incision and are not painful. Sometimes they can drain and be fluid-filled. They will go away completely as healing takes place, but it may take a little longer than the normal 10 days for healing. It is still there after 2 weeks, begins to ooze any fluid, or gets noticeably larger, then I would have it rechecked. It's unlikely to be a hernia, particularly if it resolves on it's own. For some dogs, warm (not hot) compresses applied a few times per day can be helpful.
