Animals in heaven.romans 8:19

I love horses.  They are a perfect example of God's ability to make wonderful things.  My horse had to be put down last summer, and, of course the question arose of "will I ever see him again"  Many people say that the bible doesnt say if there are going to be animals in heaven.  Well, there is a verse that says: "ALL CREATIONlooks to his coming"  Humans are certainly not ALL of creation.  I also believe animals will be in heaven because another verse says "and the lion will lay down with the lamb".  Jesus promised that everything that we enjoy will be in heaven,and,I don't know  about you,but I certianly enjoy animals.
