THis is true. Dogs have much better senses than apes. We have 3 dogs. One is especially attached to my sister. Last week, my sister had all of her wisdom teeth, including 1 inpacted, removed. Her face looked like a balloon when she came home. She was (and still is), in some pain....but so much so that she laid in bed for 2 days, barely moving. The one dog attached to her especially, Molly, laid in her bed with her, and when my sister was moaning in pain, Molly moved in closer to my sister and moaned/whined too. Very surprising. Dogs are great. A cat couldn't have cared less.
