Animals sense things we humans can't, my brother-in-law has a dog that will start barking before he see someone, in every case those people are afraid of him.
My cat is waiting for me at the door when I come home, I've made certain not to make any noise, but she is always there, when I'm sick or recovering from an operation she comes to bed with me and nudges me with her head and will often lay down and sleep beside me when it's serious, when I've had to spend the night at the hospital my wife says she is very restless, in the morning when it's time to leave for work she will walk in front of me and lay on her back inviting me to stay and scratch her tummy.
Animals manifest devotion that is comparable if not more than human love, God is love and love is eternal, ...I personally don't think it's in His character to keep shared love separated, ...human or animal.
