Burying the dog in this spot was a necessary step in their mourning. It's important that people understand how devastating the loss of a pet can be. Some animals and their human companions develop powerful bonds that are based upon sharing and mutual respect. When the pet dies, it can be heartwrenching to the owner, and the grief can be as intense as it is when a human friend or family member passes away. The length of mourning depends on the individual.
Some people have less difficulty with the loss than others.
At times, professional counseling may be advisable for those who are having more difficulty processing their grief. Friends can help grieving pet owners by offering support and showing respect for the mourning process. Belittling the situation will only make it more difficult for those who grieve for their lost animal friends. Also, showing disrespect for their sorrow will likely ruin a friendship. One common well-intentioned gesture is to get a new puppy or kitten for the person who recently lost their pet.
