Waves hand, hello. I have lived with several aussie's over the years had three and have one left, Ginger who just turned 14. In my opinion they are nothing alike. LOL. Now I have to say my boy is independent and stubborn so he is different from the get go.
Okay with my aussies I could basically raise an eyebrow and they would react "huh? what? you want me to do this, or this or this?" A wonderful quality I might add. With Eli I need a 2x4 and then maybe he will understand I want him to do something. LOL, No I don't hit my dog with a 2x4 but training him is nothing like training the aussies. That being said he is very well trained now at almost 3 but he still has an independent side.
Another great thing about aussies is that they are very light on their feet and they know where each foot is at all times. I don't remember ever being tripped by one of them, if in mid step putting away laundry I remembered something and turned the aussie got out of the way and turned with me on a dime. Eli, my dobe, uh not so much LOL. I have turned and smashed into him numerous times. He is unruffled when this happens and just looks at me like "hey, you make a decision to go one way stick to it woman". He does heel beautifully though and can change up directions when we are actually working obedience but in the house not so much.
My aussies always played gently and could get any dog/cat even parrot to play, all three were amazing in that way. Eli still plays with others like a bull in a china shop, it is his style so teaching him to be gentle with my little dogs and old gin the aussie has been an ongoing project. He is fine now but when he was a year, yikes!
My aussies were very sensitive and change could upset them not so with Eli, he is rock solid and approaches life in a very centered same attitude manner which is refreshing to me.
My aussies learned much faster BUT now that Eli is mature he learns very fast, when younger he just got bored even with treats as where the aussies lived to do things for me. I could talk to the aussies like I do people and they seemed to get it where with Eli if I want him to do something specific I have to give a command, then he does what is requested but if I am vague then forget it. I used the "get back" for an example in another post. With an aussie you can say, "get out, get back, back, move it, go on with you, go on, go" with Eli if you want him to move away you have to say, "back". If you say go he won't get it even if you wave your arm in the go away fashion. An aussie takes wonderful direction from hand and arm signals in every day use, my doberman does great when training but because he is a more idenpendent dog he doesn't respect gestures as well, again as he gets older he gets much more in tune.
Now that is just my experience and my doberman may be more headstrong than some. I know there are more biddable lines than his but I have to say I adore his personality. He is sincere, he is funny and he is very affectionate. I think the aussies (except my Sierra ) were much more moody, certainly Gus and Ginger were/are. I think if Gin had been younger when I got Eli they would have played more but she was 11 when I got him so he was a bit much for her, the body slamming and she wasn't the type of dog to put him in his place. My aussies all could go with steam all day outside but were mellow in the house, I hear a lot of aussies now a days do not have an off switch, mine did/do. Eli does too so they are a match there.
Feel free to ask me any more questions. I love both breeds but did get tired of the fur...
