What caused my dog to lose weight, vomit, and pass away suddenly?

Updated On September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Male | neutered | 67 lbs

My family and I noticed my dog losing weight so we thought maybe he needs to eat more. So we started feeding him more food. He gained a little bit back, but not much. So we thought that’s progress. But then one day I went out to feed them and I noticed he had thrown up everything I fed him the previous night. He looked really skinny too. I didn’t know what to do. We couldn’t afford to take him to the vet so we brought him inside and made him comfortable. He passed away that night what causedthis

I'm very sorry you recently lost Keylo! Please accept my condolences for your loss. Without seeing him in person, I can't say what caused him to pass away, but it could be cancer, heart disease, liver disease, or kidney disease to name some causes. I hope this helps, again I'm sorry for your loss.
