Do animals have souls? Will animals go to Heaven?
The Bible is silent on what happens to animals after they die, but simple logical reasoning from the Scriptures allows us to answer these questions intelligently. Animals do not have souls. Man is set apart from the animals because God breathed His life into him and made him a living soul: "The Lord God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living soul" (Gen. 2:7). Animals cannot sin. They do not know right from wrong, and because they can commit neither, when they die they do not go to Heaven or Hell. Animals also cannot contemplate life or think about thinking the way man can.
You might love your pets very much, but stop trying to humanize them. Regardless of how much you may love your pets, they are still just animals. They were created with no other purpose other than to glorify God, the same with the cosmos and the depths of the seas. Man is the crown of God's creation. He made us in His image: "God created man in His own image, in the image of God He created him; male and female He created them" (Gen. 1:27). Animals are not.
