Animals in Heaven
There is every reason to believe we will see our pets along with all the other animals, including dinosaurs, in Heaven. And these animals will likely be more magnificent on the New Earth than ever before. They may even be able to speak. The condition of animals we witness now, just as with all other creatures and creation, is a result of the Fall. Creation has a destiny planned by God and longs to see it fulfilled. Man sinned but the remaining creation did not. Yet, all creation suffered by the downfall of man. "Creation will be delivered from the bondage of corruption" (Romans 8:21). And since "there shall be no more curse" (Rev.22:3) there will be peace amongst the dinosaurs and all of creation.
Man is not the only creature affected by God's judgement. Throughout the Bible we read passages where God brings judgement "on man, on beast, and on every herb of the field, throughout the land of Egypt" (Exodus 9:22). Luke tells us in 3:6. "all flesh shall see the salvation of God." The Greek word for "flesh" is sarx which translates to "the soft substance of the living body which covers the bones and is permeated with blood of both man and beasts." Christ did not die for animals in the same way He died for mankind but animals (all flesh) will see the salvation, indeed the Redeemer and the redemption of our bodies (Romans 8:23).
"Behold, I make all things new" (Rev. 21:5) does not indicate that God will make a new human race or make us a new pet, although He certainly could. A new race of humans would not need redemption. Additionally, "For behold, I create new heavens and a new earth" (Is. 65:17). Again, God is making all things new, not making new things. Just as we become a new creature in Christ upon salvation, we retain the same body, but new things have come. "Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new" (2 Cor. 5:17).
Before the Fall, the serpent spoke to Eve in the Garden of Eden and there is no indication that Eve was surprised by this. Moreover, Genesis 3:1 also tells us that "the serpent was more cunning than any beast of the field" which implies that all the other beasts were also cunning. We may be able to experience our pets speak to us on the New Earth. Does any pet owner reject the notion that their pets communicate? In Revelation 8:13 John heard an eagle flying overhead say in a loud voice, "Woe, woe, woe to the inhabitants of the earth, because of the remaining blasts of the trumpet of the three angels who are about to sound!" Granted, the story in Revelation is recorded in apocalyptic literature but when the serpent spoke to Eve and the donkey spoke to Balaam, the stories are recorded in historical narrative and can be taken literally. For the same reason, some of the apocalyptic passages in Revelation can be take literally. For example, "And every creature which is in heaven and on earth and under the earth and such as are in the sea, and all that are in them, I heard saying: 'Blessing and honor and glory and power Be to Him who sits on the throne, and to the Lamb, forever and ever!"(Rev. 5:13).
 Romans 8:21-23. For the creation was subjected to futility, not willingly, but because of Him who subjected it in hope; 21 because the creation itself also will be delivered from the bondage of [f]corruption into the glorious liberty of the children of God. 22 For we know that the whole creation groans and labors with birth pangs together until now. 23 Not only that, but we also who have the firstfruits of the Spirit, even we ourselves groan within ourselves, eagerly waiting for the adoption, the redemption of our body.  Some others include Jeremiah 7:20; 21:6; Ezekiel 14:12-13,17.  https://www.blueletterbible.org/lang/lexicon/lexicon.cfm?t=kjv&strongs=g4561  Is. 65:17 – 19, “For behold, I create new heavens and a new earth; And the former shall not be remembered or come to mind. 18 But be glad and rejoice forever in what I create; For behold, I create Jerusalem as a rejoicing, And her people a joy. 19 I will rejoice in Jerusalem, And joy in My people; The voice of weeping shall no longer be heard in her, Nor the voice of crying. Or behold, I create new heavens and a new earth; And the former shall not be remembered or come to mind. 18But be glad and rejoice forever in what I create;  Some versions read "angel". The NU-text and M-text use "eagle".
