I'm having a bad time.

Show photos of your Labradors, I would really like to get out of this bad time.

This is Kiara, my first dog. (GermanShepherd x lab mix) She was so much fun and I still can't believe what happened. Yesterday everything went relatively normally, she was fine and on the 20th of the following month she would be 3 years old. Yesterday after returning from school I went out and saw her. She was fine, to be honest, she was great. I fed her and took her to the garden while I did my homework. I don't know who or how, but someone mercilessly dropped an unknown pill into his water and when he took it he had convulsions and apparently tried to enter the house but when jumping one of the benches he fell and being so weak he couldn't get up... that's what the investigations that have been done so far about his death have said. I am really devastated and I don't know how to act in this grief.
