Apparently.
My dog (neutered Greyhound) greets other dogs with his tail straight up in the air and his head and ears up. If he wants to sniff another dog he bends his head down but still trying to keep it up at the same time, so he ends up with an arched neck :o (he has a long neck)
I took him to a very small dog show on Saturday put on by the local Girl Guides pack, the Greyhound charity we got him from were there too with a couple of kennel dogs and my boy greeted them as described above ^^. Someone commented that he was very dominant to which a few other people agreed that he was.
I didn't say anything as I wasn't sure about dog - dog dominance, even though I know dog - human dominance is a load of crap.
He can get quite shirty with select other dogs, he intensly dislikes un-neautered males, goes bonkers (barking and growling plus doing the 'fish-on-a-line' routine) whenever we see them out and about. As a safety measure he always wears a muzzle whenever he leaves the house through the front door. Is he dominant or does he just have issues? Why does he greet other dogs in this way?
