  Dogs can die for as many reasons and in as many ways as humans can. They can get cancer, be poisoned, have heart attacks, get hit by a car. The list is endless.My Lab â¦ rador retriever just recently passed away from lymphoma, a type of cancer.It was heartbreaking and I miss him very much.es, sometimes the dog will act out. If your pet is used to you, it will know something is different. Hormonal changes occur, and the dog can sense that. They may not know wha â¦ t is going on, but it knows something is!
