What caused my senior dog's coughing, seizure, and sudden death?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry about Chandelle! There are many possible causes as she was a senior dog. Heart failure, a seizure that caused aspiration or non-cardiogenic pulmonary edema, choking, a severe allergic reaction, twisted stomach or an internal bleed. With out an autopsy we will never know. Again I am so very sorry for your loss!

I'm very sorry to hear about the loss of your dog. It's possible that he may have had a stroke or blood clot secondary to his heart disease that traveled to his brain. Or, if he was regularly having collapsing episodes due to his heart (syncope), what you saw may have been one of these that was especially severe, as this is a common cause of sudden death in dogs with severe heart problems. If you want to try to get a more definite answer on what the cause of death may have been, you would need to have an autopsy done, called a necropsy in animals. Your veterinarian should be able to let you know where you can have this done, if it's something you want to pursue. Again, I'm very sorry for your loss.

First off, I'm extremely sorry Belle died suddenly! Please accept my condolences for your loss. Without seeing her in person, I can't say for certain what caused her to die, but it could be she was suffering from heart disease. That would cause a cough, and can lead to sudden death. If you want a definitive answer, you could take her into a vet for a necropsy (an autopsy for dogs). Again, I'm very sorry for your loss.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry for your loss! I do see pleural effusion (fluid) on the X-ray but I would also suspect a mass, which is likely the cause of the fluid. That could be why your Vet couldn't get any. Most of the white on the X-ray is likely the mass and only a small amount of fluid. I wish you the best!

Oh no, I'm so sorry that you suddenly lost Minnie Mae Pearl! How horrible for you, please accept my condolences for your loss. Please keep in mind I can't say for certain what caused her to pass away, but I can offer some guess. It is possible that she had cancer. It's common in senior dogs, and it can be festering for a while before the dog sudden becomes ill. They can't tell us when they are sick and are pretty stoic with pain, so oftentimes when we notice something is wrong, it's very late in the disease. That happened with my own dog last year. He seemed perfectly normal, and then one night he appeared to crashed. I rushed him into the clinic for treatment, and he had an abdomen full of fluid likely from a ruptured splenic tumor. He had shown no other signs of illness before then, and unfortunately I had to let him go, so I completely understand how hard it is to suddenly lose a beloved pet and feel devastated. Her death could have also been caused by liver disease, pancreatitis, or a number of other illnesses. I wish I could say for certain to give you some answers, but I can only offer my guesses and my sincerest condolences for your loss :-(

I am so very sorry to hear about Koko. Without having examined him it is very difficult for us to give possible causes, and your vet is definitely the person to ask for this information. Possible conditions that could cause the symptoms you describe could include tumors in the brain, stroke, a herniated intervertebral disk compressing the spinal cord, trauma, a tumor bleeding into the abdomen causing severe anemia and weakness, just to name a few. It sounds like Koko was suffering and you did your best to alleviate his suffering. I am very sorry for your loss.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Coughing and bringing up clear liquid could be coughing up stuff instead of vomiting. This is important to try to differentiate. Coughing up liquid is more consistent with heart disease. The x-rays are difficult to read as the image transfer through is of poor quality and to really assess the lungs you need good quality images, however the heart does look a bit enlarged and the lungs do look a bit 'white'. I cannot assess the liver on these radiographs as you cannot see them. An enlarged heart, white lungs (fluid in the lungs), and an enlarged liver is consistent with both right and left sided heart disease. I recommend you return either to your vet, or another vet, and get a specialist ultrasound of the heart (an 'echo') to determine if heart medications are required. Your vet can also listen to the heart to see if a murmur is present in the heart, or 'crackles' are heard on the lungs. Heart disease is very serious and needs medications to manage. Without these Lily unfortunately will essentially drown in her own lungs, if heart disease is the problem. I suggest a recheck as soon as possible to get this figured out. Best of luck with Lily, I hope she feels better soon.
