There is no mention in the Bible of a pet heaven or dog heaven—and for good reason. Animals cannot take the steps needed to qualify for “the heavenly calling.” (Hebrews 3:1) These steps include taking in knowledge, exercising faith, and obeying God’s commands. (Matthew 19:17; John 3:16; 17:3) Only humans were created with the prospect of living forever.—Genesis 2:16, 17; 3:22, 23.
No. The Bible says that both animals and humans are souls. (Numbers 31:28) When the first man, Adam, was created, he was not given a soul but “became a living soul.” (Genesis 2:7, footnote) A soul is composed of two things: the “dust from the ground” and “the breath of life.”
No. To sin means to think, feel, or do something that violates God’s standards. In order to sin, a creature must be able to make moral decisions, but animals lack this ability. They usually act according to instinct during their limited life span. (2 Peter 2:12) At the end of their life span, they die, even though they do not sin.
