What is a word of mourning for pets?

1. The dog is dead. I just found out today. In fact, this dog has never been very lucky.

The puppy died today, which brought me so much pain.

My dog died today. I'm so sad for comfort. Although it's only been half a year, you are always with me when no one is at home.

A dog who grew up with him for 6 years died, and he didn't want to have a dog anymore, for fear of being sad.

When the dog died, he died in front of me. It's bloody and terrible. I kept crying and crying. I woke up in despair, and then I was so sad.

6. One dog died and the other buried his companion. Sometimes people are really not as good as dogs and are moved to cry.

7. Life didn't treat me well. My mobile phone is broken, so I bought a new one. The dog was run over by a car, and there is no dog at home.

8. How to treat neuritis in dogs? My dog is going to kill me.
