Horses Dogs Lot

How is there proof that my pets (all past and present), will go or are in heaven?. I have heard responses, but nobody has asked till now. I know that there is someone that said has actual proof. Can you let us all know our pets are there after? Past and present pets for me, horses, cows, llamas, dogs, (the most, I have had and have a lot), and birds, love them all and unlike knowing what is in store for believers would like to know if, there they will be our friends. Have not read anything like this in the Book. But the questioner said there was proof.
