my dog died

Me and my uncles were going to my uncle’s ranch to get bull to where he had other cows to hang out with them.My dad told my uncle to get the truck connected with the trailer so, he went and got them connected. While he was doing that my dog had to do his business and I took him out. My uncle was getting the trailer to the bull, and my dog was doing his business. My uncle didn’t see him and he got ranned over. When I came out of my house I saw him laying there dead. I was about 8 and I started crying, I told my dad to burry himĀ once I came out he was gone already.
