Can you go to the cemetery at night?
Some are public and you can visit any time when they are open (usually dawn until dusk). However, some cemeteries are on private property and you might be trespassing if you show up without having talked to whoever is in charge. This is why it is important to do some research before you embark on your graving journey.
Do dogs understand death?
Since they may not actually understand death as something permanent, sometimes a dog will wait patiently, believing that the deceased caregiver, will return. Still others believe that the dog may just be reacting to the grief exhibited by humans in the house as they deal with the death of a household member.
