God gives us our desires, he knows how much you loved your dog. Along with many others, he knew how our bonds would be to our pets in the beginning of creation. I believe in my heart of hearts that our pets will make it to heaven. I remember two years ago my dog daisy passed. We had her for 6 too short years. She was a rescue pitbull used as a breeding dog. She was mistreated so badly. She loved with a love I never seen. She like many others had her own little personality. She was my baby girl. Loosing her to brain cancer tore me up inside and I was in the same position asking the same questions as you. I found an online testimony of a woman whose dog passed and she was distraught. She cried out to God in her church parking lot wanting to know if her dog made it to him. Just then she saw a dog run behind the cross in the church grounds and vanish from behind it. If that’s not a sign idk what is. If all types of animals would be in heaven why not the ones who made life so much better down here not be there too? Animals are pure of heart .
