My sister lost her dog during an already hard time
Hey everyone, my older sister suddenly had to put down her dog that she had for 9 years on Friday night. He started to struggle with breathing this week and was at an animal hospital for 2 days. My sister and her boyfriend wanted to come pick him up on that Friday because they were told that he was feeling better. But once they arrived at the parking lot, they got a call, informing them that he was suddenly feeling very bad again, so they had to make a choice to relieve him from his pain. He shed some tears when he last saw his owners before leaving the world.
Obviously, my sister is feeling devastated, just like the rest of the family. Timing couldn't be worse because our father was diagnosed with stage 4 cancer of unknown origin 2 months ago and his doctors expect him to pass away within the next couple of months. Would appreciate some advice on how to best deal with this situation now and what I could do to support my sister while we're already feeling down because of our father.
