Some dogs have been so thoroughly "humanized", that it's scary.
Hopefully, I won't need to defend my view on this. :)
Not from anything I would say. My dog, a Shiba Inu has a new surprise for me almost every day. From the time he dropped his rubber chew bone on my crying baby boy's lap, to just yesterday when he got very excited when hearing the first ice cream truck of the year, he is always reminding me that though he has four legs and a tail, he is one of the family. One of us.
It's really fascinating to watch a group of animals interact. We have six dogs and you can watch them for an hour and figure out where each falls in the pecking order.
When you get to know them you can understand their moods. They grin when I get home from work and they look depressed when they see me get ready for work (they're probably mirroring my moods). I have a big Chow that slaps me when he wants something. When I ask him what he wants he'll lead me to it. He'll go to the back door if we wants out, he'll lead me to the utility room if he wants food, and he'll lead me to the water dish if it's empty. I'm a dog servant.
Not to me. Owned by a series of dogs since childhood.
Of course, animals have feelings. I went out of town this weekend. My wife said one of our dogs that sleeps beside the bed cried when it was bedtime and I had not come home. :-( But I received a joyful reception when I returned home. :-)
