My dog had clear fluid from her mouth before dying. What was it?

Hi, I am sorry to hear that Mary passed away so suddenly. It must have been a real shock for you. I think the fluid you noticed is inflammatory fluid coming from the chest because of the presence of cancer. This is secondary to the presence of the tumour, sadly can’t be treated and does aggravate the breathing itself. I hope Mary did not suffer. Thinking about you at this difficult time.

Hello, I am so sorry to hear of Indie's passing. Clear fluid coming from the nose is a common post-mortem event that likely did not have anything to do with her passing. It is possible she had respiratory disease that could have caused excessive nasal drainage though. A veterinarian could perform an autopsy and try to confirm a cause of death. Dogs can experience heart attacks and strokes as sudden causes of death, even in young age. I know unexpected loss can be very traumatic, but please do not blame yourself. Thanks for using Petco Pet Education Center, formerly Petcoach. I hope this is helpful.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! As a breed, Cavalier King Charles Spaniels tend to be very prone to heart problems. Sadie was most likely to have passed because of a heart condition known as mitral valve endocarditis. There are other possibilities, but this is the most likely. It leads to congestion of the lungs and basically causes them to drown in their own serum. Without an exam before and after Sadie's death, it is hard to know for sure. I hope this brings you some peace. May you find comfort in your time of grief.

No leakage of clear fluid from a mammary tumor does not indicate that you have to euthanize her. Sometimes tumors can ulcerate (open up) and leak fluids, but usually the fluid consists of blood or pus, so I am unsure why the fluid here is clear, unless there is another component to the mass that is cyst like. Apply pressure to the area to hopefully stop the leakage, and if needed have your vet take a look at the area to determine if anything else needs to be done to manage it.

I'm so sorry to hear this happened. I would not say that blood is normal unless there was concurrent trauma. With drowning usually the fluid that comes from the nose and mouth is frothy, clear/white/grey and not bloody. If you want to get a better idea of what happened to him you could have your vet do an autopsy on him.

I’m so sorry for your loss. It’s not unusual for their mouth to be in a variety of different positions at death, and depending on their skin type and breed, some dogs will appear to have their eyes closed. So the way you found her isn’t terribly out of the ordinary. I am so sorry for your sudden loss. Let us know if there’s anything else we can help you with.

Oh my goodness, I am so sorry to hear this! I would be concerned that Maya either got into something toxic while she was out running around or she became overheated and died of heat stroke. There is also a chance she could have had an underlying heart condition that was never diagnosed. Finally there could have been some sort of trauma she encounter like being hit by a car. The watery blood that came out of her nose has most likely come from her lungs. This can be abnormal finding after an animal passes away under more traumatic circumstances. If this recently happened you could take Mays's remains in to your vet and request a necropsy be performed. This may help determine her cause of death. Much sympathy to you.
