Just sharing my exp as a previous dog owner:
I adopted my dog when she was 8 years old. She passed away last year at 16 and yes, I was very sad when she passed on. It was tougher in the last 2 years when she had dementia. 8 years is not a long period but it is not short either. Since there is no one at home during weekdays, she will be left alone at home but I don't lock up her in a cage juz let the roam ard the house with the fans on. But ya, the heart pain is real when I had to make the decision to put her down especially when I see her old age body getting weaker and weaker day by day.
I still rmb on the day of cremation, the staff asked me 'Sir, can I have your permission to carry on with the cremation'? My heart drop and wept...
In memories of her, I still keep her bed, her clothing , her pics in the house and my phone wallpaper. Everyday, I will greet her good morning and good night when before I turn in to bed. You may think it silly but I also told her to jiayou whenever she is on the other side over the rainbow bridge as much as I will also jiayou in our world.
For pet owner, this is as good as losing a family member.
