Why did my senior dog decline so fast and die suddenly? Is it normal?

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 very sorry to hear about your loss of Libby. Unfortunately as dogs get older they are more likely to have heart issues and organs that do not work properly. Without testing I am not able to tell you exactly why Libby passed. I know it is difficult to deal with a loss.

Oh no, how horrible for you to experience! I am so sorry for your loss! She could have had heart problems, cancer, liver failure, or possibly something toxic you didn't realize Bella got into during the day. Without seeing her in person, I can't say for certain what caused her to pass away, but I do recommend taking her into a vet for a necropsy. This is an autopsy for dogs, and it may give you some answers on what caused her to suddenly pass away. Again, I am so very sorry for your loss, please accept my condolences :-(

I'm very sorry Lizzy passed away today! Without seeing her in person, I can't say what caused her to pass away, but common causes of death in senior dogs include heart disease, organ failure, and cancer. If you want to know why she passed, you could bring her into the vet for a necropsy (an autopsy for dogs). Again, I'm very sorry for your loss.

I'm sorry to hear about Hurley's passing - she sounds like a wonderful dog. From what you describe, I would agree that lymphoma or a similar type of cancer is the most likely diagnosis. There are no toxins that would cause dramatic lymph node enlargement like what you're describing here, so the substance she ate on the beach was likely not related. And unfortunately yes, dogs with aggressive types of cancer can get very sick and go downhill very quickly from the time they first start to show obvious symptoms. So I would agree with your veterinarian that this is almost certainly what happened in your girl's case. It sounds like euthanasia was the right decision for her, although I know that definitely don't make it any easier. Again, I'm very sorry for your loss.

I am so deeply sorry for your loss, my thoughts are with you in this difficult time. It is of course difficult to know precisely what happened to Daisy without examining her, however, I would be concerned about two possible conditions. Bloat which is when the stomach becomes englarged and may rotate. This causes the blood vessels to constrict and affects blood flow to and from the heart. It is common in large barrel chested dogs. Another possibility is A foreign body obstruction, which occurs when something becomes lodged and Blocks the gastrointestinal tract, the bloackage can be complete and cause a rupture. Again it is difficult for me to know what could have caused Daisy to pass. If you need to know definitively, a local veterinarian may be able to perform an autopsy. Sending my deepest sympathies to you.

I'm so very sorry you lost Koda so suddenly! Yes, that can happen to older dogs where they pass away in their sleep. She could have had heart disease that caused her to pass, but without a necropsy (an autopsy for dogs), I can't say for sure what caused her to pass. Again, I'm sorry for your loss!
