Our wonderful greyhound has recently been found to have a tumour in her lung, she has also recently stayed at our vets as she has pneumonia. She is on antibiotics, anti inflammatories and an anti emetic, but worryingly, today she coughed up some mucus with fresh blood. What could it be?https://www.vetclickforum.co.uk/read.php?7,1582,1582#msg-1582Mon, 01 Jun 2026 10:49:18 +0000 Phorum 5.2.23 https://www.vetclickforum.co.uk/read.php?7,1582,15093#msg-15093 https://www.vetclickforum.co.uk/read.php?7,1582,15093#msg-15093
I was so sorry to hear about the sudden and sad death of your lovely labrador.
Without a proper autopsy, the cause of death is a matter of speculation, but by far the commonest cause of a sudden massive haemorrhage is warfarin poisoning. Warfarin is a commonly used rat poison which is usually lad as a bait mixed with oatmel, which many dogs find attractive, and labs will never pass by anything that remotely looks like food!

Another possibiloity if an aneurysm of a pulmonary blood vessel which ruptured, but that would certainly need an autopsy to confirm.

Recently, my 2 year old cream colored lab started coughing up mucous. Within 24 hours it was frank bloody, turning to clots. I notified my Vet immediately. I had her hospitalized at 2 different Vets hoping to get the bleeding to stop, Vit K, steriods, Oncontic fluids were given. Her xrays showed fluid buildup around the right lung.The heart shape was visable and everything looked intact. She continued with coughing blood. I am assuming that she developed respiratory distress. She died (after 4 days). I am NUMB - she was my everything!!

Her stools were clear of any blood. She was still urinating and drinking water, she ate some food until the last 2 days. Could this have been a poisoning? I found an old paint can in my yard with what looked like dog food in it. That same day, my golden retriever came in drooling. I took the can to my Vet to have it examined and am awaiting results. What kind of poison would cause a respiratory bleed or distress??? Does this sound like an anomoly? I am wanting to know the cause of her death. What causes lung bleeding. I am hoping it was an anomoly.

I would not consult to an autopsy. I wanted to bury her without any defects if possible. I loved her. My friend and I carried her (76lbs) up to a remote ridge in where she is at rest. It was all I could do out of respect and love was to repay her with providing her a spectacular resting place.

I am stuptified and filled with grief, as to what could have caused this. Would you please shed light on possible causes? I just can't understand how a poison could cause a right sided lung bleed. The toxicology tests are not back regarding the food in the can. I did find numerous vomit in the yard with abnormal pieces of meat. I did not feed her meat like I found.

What could cause an anomoly for a vessel to bleed in the lung and not stop bleeding? Could you please shed some light on this, as I would really like some closure. Thank you so much.

Has he been checked for a fungal infection such as Aspergillosis in his nasal passages? This can sometimes cause occasional bleeding when a small blood vessel is eroded. The usual antibiotics will not treat this condition.

I am sorry to hear that you have lost your dog, but I applaud your decision to have him put to sleep as soon as a positive diagnosis was reached. So many people find it difficult to make this decision, thereby inflicting further suffering, albeit unintentionally, on their pet.

My springer spaniel Patch aged 13 years developed a cough and was panting I took him to the vets and they prescribed heart medication for a heart murmur we were told to monitor his breathing and also check in case his gums turned blue in colour. the vet was quite hopeful that this could be kept under control with medication and asked to see him again in 2 weeks.that night his breathing got more frequent about 1 breath per minute and he then started to bring up blood in his mucous i took him to the vets and after an xray it was believed that his right lung was full of blood and that the probable cause was a tumor I made the decision to have him put to sleep as there was nothing that could be done for him,and i did not want him suffering any longer.the reason for this email is for other people to not hesitate if there animal coughs up blood,as the symptoms ,(as in Patchs case )came on very rapidly and i was fortunate to get him to the vets without to much suffering. Patch was a real character and an ex police sniffer dog that had a wonderful life and I hope that if this is published people will remember him and hopefully another canine or feline friend will be saved any pain and suffering and he will not have died in vain. thankyou once again for a helpful site. .Regards Tony]]> tony Ask The VetThu, 10 Jul 2008 18:02:56 +0000 https://www.vetclickforum.co.uk/read.php?7,1582,8843#msg-8843 https://www.vetclickforum.co.uk/read.php?7,1582,8843#msg-8843
Have you not had her to your vet?

Persistent vomiting can be caused by several things, and does need to be properly diagnosed and treated.
She may have swallowed something which is causing an obstruction, she may have an acute gastritis, or she may have ingested something poisonous.

I am so sorry to hear that your lab is terminally ill at such a young age.
With such widepread malignancies, and clearly no real quality of life, I think you owe it to him to bring an end to his suffering. Fortunately we are able to do that for our pets. I really do know how difficult it is for you to make that decision - I lost two of my own labs with cancer, one at 4 and the other at 6 years of age.

I got a 8 month year old dog, perfectly fine when she was at the humane society; we adopted her. She just started sneezing out blood today. Besides that, she has been coughing/yacking every 5 minutes off and on. We put her in the backyard since we dont want the blood staining the carpets etc.
She went into the backyard and started tearing up grass and then she started biting at her leg.
I doubt this is from allergies; the only different thing is i used this accident cleaner to spray after i picked up her dog poop (in the house)

I' am really worried about her can anyone help me out?]]> luke Ask The VetSat, 03 Nov 2007 23:44:31 +0000 https://www.vetclickforum.co.uk/read.php?7,1582,6464#msg-6464 https://www.vetclickforum.co.uk/read.php?7,1582,6464#msg-6464
There comes a time when we have to exercise the privilege we have of ending the lives of our pets when the quality of that life is no longer satisfactory.
You clearly realise that you are fast approaching that time, and I applaud you for it.
The last thing that I think one should do with an old and infirm dog is to subject it to tests and examinations which may well prove nothing beyond that it is terminally ill.

Use your judgement, and do what you know is the right thing.

It may be that he has ruptured a small blood vessel which has mow repaired itself. That can happen, and if so it is nothing to worry about. If it recurs, it should be fully investgated.

Is the blood bright red, or is it changed - looking like coffee grounds?
If the former it will be coming from the lungs or the throat, if the second, it will have come from the stomach.(it is always possible that it could have come from the lungs, swallowed and brought up again in a darker colour)
In either case, a number of alternative possibilities will need to be considered.

Coughed up blood can come from either the lungs, the throat or the stomach. A full work-up by your vet, including blood tests, is necessary to try to identify the source.

I echo Walter's comments. Even when you know it is for the best, it still takes courage to make the decision and still often leaves a feeling of guilt behind.

There is no doubt you did the right thing at the right time for Daisy. They say time is a great healer. It isn't, of course, such a wound can never be healed. But in time you will learn to live with her loss, and remember the good times you had with her.

Wel, we still don't know for certain that the 'tumour' is a tumour, as the vets at our practice seem to have differing opinions. However, very sadly Daisy has in fact deteriorated and although no longer coughing up blood she is coughing a lot and her breathing has become laboured. She has lost another 1.2 kg. We took her back to our vet this morning and she has prescribed prednisolone in a last ditch attempt. If she is not better in a few days we will have her put to sleep. A very difficult thing to do, but as I have said before I would never let any pet suffer, unless they were surely going to get better. It is particulaly sad as Daisy is only 6 or 7, not absolutely sure as she is a rescue. However she is such a wonderful dog, so gentle and not a bad bone in her body, as with most greyhounds.
