I think dogs get jealous, and some females take jealous to a whole other level. I call it the Green Gene. They have a lot of the same emotions we do, they are are canine emotions, which are different, maybe more raw, more simple, deeper, stronger, and some dogs have a much harder time not reacting to their emotions. Fear, anger, jealousy, grief, loneliness, excitement, contentment, playful or happy, and others.
people conceal their emotions, dogs only do so if they have been trained (usually replacing that emotion with fearfulness, and training them not to respond to fear normally). If a dog who is fearful or angry growls, and is beaten for growling, they may just cower or go to the next step.
I am really up in air about anger. How much of the anger that we see, even in dog fights, even in the dog that started the fight is not anger but fear? A dog sticks its hair up, and barks and lunges like a nutcase, growling, snarling, snapping. Basically the dog is saying get the heck out of here! But jealousy turns into anger, turns into rage.
A dog that rages without jealousy, I don't know, that seems like it might be a problem with how they are wired or a disease of some sort affecting their brain.
I don't know about fair play either. Some of my dogs are let out in the field to run, some are not. Sometimes I come home with bones for five of them, the rest of them do not get bones. I don't get the stink-eye, the bone-receivers do not get the stink eye. Mostly the girls are anticipating and hopeful that I will get to them and give them a bone. If I say, "That's it, that is all I have," They will turn and go back to whatever they were doing. And Joy will start working on a plan to relieve a bone-receiver of their prize. (Somehow she always succeeds too -- and they are in separate kennels!) But there is no animosity, so I suppose the dogs do not resource guard treats or food. Good.
It is funny though, some of them will cry and bitch when I pay attention to a specific bitch. Odie will bitch and moan if I pay attention to Jenna. Ninja will bitch and moan if I pay attention to Heidi. It is seriously interesting. I am sure letting those pairs get together would be a mistake. On the other hand, Tori shows her werewolf teeth toward Jenna and Jenna doesn't give her the time of day. The same with Ninja. Ninja broke free of a crate while I was moving Jenna and her pups from one kennel to another, and Jenna grabbed her by the muzzle and held her down. I grabbed the puppies and put them in a kennel and then dragged Ninja by the tail into another kennel got the gate between and finally got them separated. Ninja was hurt and angry. Jenna wasn't even shaken up. I put her back in with her good sized pups, and no problems. Jenna is three years older than Ninja, but they are both mature bitches. I think there is something not quite right with Ninja.
But yes, canine emotions are very interesting, and as for jealousy and love, if it looks like jealousy or love, and it acts like jealousy or love, than I don't see the problem with using the terms, so long as we maintain the understanding that these are dogs and not humans.
