Can dogs smell death?

My grandma recently moved in with me due to health issues, although it was supposed to be a temporary situation. Heartbreakingly, she died on Friday (2 days ago). She went back to her house for a “vacation” and died in her recliner. Her dog is at my house and I have been a wreck, obviously. I feel like he can sense something, but I was planning to bring him to her house to let him sniff around. I’m hoping that will help him understand. He was originally my dog, but I gave him to my grandma during COVID lockdowns so she wouldn’t be alone. She’s had him for 3 years. He’s back to my dog again. He’s normally very clingy (Havanese) and normally will follow me around but it feels different right now. Maybe I’m just projecting cuz I’m so emotional.
