Dogs do have emotions.

I have some friends that think, or have determined through some readings from some researchers that dogs dont have feelings or emotions. well, ive been reading through some research, cause i 100% disagree.
emotions come from a part of the brain that is considered the most primitive, and is present all mammals, reguardless of the size of brain. and, these animals do produce the chemicals needed to generate the physical side of emotions (ie. seratonin, GABA, norepinepherine, dopamine..etc.) anyway, i dont want to dispell all the little things but i do want to throw it out there for discussion, (even though not too many people are frequenting this blog..buuttt i dont care). On one side of the front people say dogs are based on biological instincts and training, that their actions are based on straight animal instinct...again i disagree whole heartedly...or they say that dogs react based on what theyre trained. this i do agree with but, it's relatable to us as well...its the hot stove experience...we know not to touch the stove cause it hurts, well a dog knows to "sit" or "shake" cause he/she is getting a treat...and the feeling is that this is an example of almost like a programming..but..my problem with this is.. we do the same thing..its the "if you do this ..this will happen" so then you keep doing it..or stop doing it. there are several thousands of studies throughout the past yrs that will say that they do or they dont, i say they do. heres some examples. when im at home with my dogs, you can sort of notice their moods, good, bad, irratable...etc...and..reguardless of these moods, they are always up for showing you graditude with a "kiss" or other various signs of love, also they are always will to protect the house, their domain, but it's deeper than that. not only are they standing up for their den, but those that live in it..even other dogs biologically unrelated, why?..cause they are now EMOTIONALLY connected to them. the fact that when my wife leaves, all the dogs are sad and sit by the door for about an hour..reguardless to what i say to them. im home, but because someone is missing from there fold, the lead female presence..they are saddened..
alot of people want to believe that dogs dont have emotions and want to disconnect the idea they they feel. im not sure why they want to try to reason the idea away but, beautiful things can happen if you except the idea that they do, that they even understand your feelings, whether it be based on body language or chemical emissions from our body..they know.
heres another quick example; my dog edward, who is an amazing dog..almost too smart for his own good. if we're away at work all day and he does something like grab the bread off the counter and eat the whole loaf, or get into the garbage..he'll be hidden before we enter the house, not after we enter, not after i say anything but before we enter and find the mess he created. i feel that this is guilt.. he knows he did something wrong, i didnt have to say anything or even point it out..he just knew...lil devil...i love him..
