Why did my dog die suddenly with bloody poop & weight loss?

Due to the blood in the stool the death was more likely from parvovirus or a severe case of intestinal parasites. Dogs that are poisoned often vomit and have seizures. Thanks for using Petco Pet Education Center, formerly Petcoach to help you get answers to your veterinary questions.

I am so sorry about Elsa. If Elsa was a puppy and just had on vaccine she was not fully protected. I would be concerned about Parvovirus at that point. Other then that it could be hemorrhagic gastroenteritis or even a foreign boy obstruction. It could also had been a type of cancer. Without more information it is hard to say definitively what caused this without more information. You can always ask for a necropsy and your veterinarian can send sample out to the lab to try to get an answer. Thank you for using Petco Pet Education Center, formerly Petcoach.

First off, I'm sorry that you lost your dog so suddenly. Please accept my condolences for your loss. I'm only guessing here, but if he wasn't vaccinated, it could have been parvo that caused him to pass. It could also be that he had a foreign body, a severe GI illness, or if he was fed a raw diet, the bacteria from the raw diet could have made him extremely sick. Again, I'm sorry for your loss.

Poor Boomer, I'm so sorry! For him to die so suddenly it must have either been a very serious infection that progressed quickly or he may have had an issue such as a tumour or heart condition that had worsened over time. It would be impossible to speculate any further into what caused his death. Most importantly it does not sound like he suffered, he was a good age and I don't think there would have been anything you could have done.

Hi there! I am so, so sorry to hear about Boo. Losing a pet is never easy, and losing them suddenly is even harder. Unfortunately, there's no way for us to tell for sure what happened to Boo without completing a necropsy (post-mortem examination and testing). From the symptoms you mentioned (bloody stool, seizure, lethargy), it could have been multiple issues, including a bacterial infection, gastric ulcer, viral hemorrhagic disease (a virus that can cause bleeding and seizures), parasites, or a clotting disorder. Rabbits are generally very good at hiding their symptoms, so if Boo got sick very quickly, you may not have noticed anything wrong. There was likely nothing that you could have done to prevent this if she was acting normally. My deepest condolences to you and your family.

Thanks for using Petco Pet Education Center, formerly Petcoach! I am so sorry to hear about your pup. These are very general signs that could have happened due to many different conditions such as ones affecting the heart or it could have possibly been due to internal bleeding. It is hard to know with just a brief description provided but those are some things that can affect a dog suddenly. So sorry to hear this again.

Hello. I am so sorry about your loss. If you are looking for a cause, only a necropsy done immediately after death could give any answers. Otherwise, Rocky's death could have been due to trauma, intoxication/poisoning, or massive GI infection/blockage/intussusception. Please accept my condolences on your loss & thanks for using Petco Pet Education Center, formerly Petcoach.
