Nova Scotia Duck Toller

Not meaning to be rude but I thought I'd correct your spelling. It is Nova Scotia Duck Tolling Retriever (or Toller for short). The spelling does not have an 'R' in it
 
The Toller is my breed of choice, and truly the only one I really want to own at all times in my life. I love absolutely everything about them. I'll try to share as much as I can about them with you, and I'm sure I'll end up saying some stuff you already know but I hope I can help.
 
I don't reccommend Tollers (Nova Scotia Duck Tolling Retriever) often, but since you already have an Aussie I'm sure you know what it's like to have an active dog constantly on the go . The Toller is a medium sized breed. Females are between 17-20" (preferably 18") tall, and weigh between 37-43lbs. Males are between 18-21" (preferably 19") and weigh between 45-51lbs.
 
I'm not sure if you have cats or not, but Tollers doe have a strong prey drive and I'd never trust one alone with a cat. That being said though, they can live with cats peacefully. I've loved Tollers all my life and have been researching them for atleast 10 years now...which is a long time considering I can't even have a purebred until 2008. Tollers are very high energy, high drive dogs. They need something to do, or else they will find a way to amuse/entertain themselves. They can become destructive and barky if not stimulated enough each day. They require a lot of exercise, but they will lay down in the house while you want to watch TV or something. I have a Toller/Border Collie mix at the moment. She gets 2 jogs a day, aswell as a walk which ends up in a romp/play/run/obedience practice aswell in a nearby field. Now, they don't neccessarily NEED 2 jogs a day, that is just something I like to do. They DO need daily walks though and atleast an hour (preferably more) of playing/retrieving each day aswell as mental stimulation. Tollers love to work, they love to please. However, that being said, they do get bored if you repeatedly do the same thing over and over again. They thrive on learning new things. Tollers can also be pretty stubborn and often their intelligence can do more harm than good...they're almost too intelligent for their own good. Owning a Toller is like having a 2 year old child for 12-14 years. Tollers MUST be socialized tons and it is extremely wise to take them to puppy classes and atleast one set of obedience classes. If not, they can become very fearful around new things and I've known a few to become fear biters and barkers due to lack of socialization as a young pup. Socializing has to continue for the rest of the dogs' life aswell, not just as a pup. Tollers love to be with their family. I find that they, in general, much prefer people over other dogs (they do get along with other dogs though). They don't like to be left alone for long periods of time, but a lot of breeds don't.  If you are truly interested in this breed and would like to know more, please don't hesitate to post any specific questions here I love talking about Tollers, and love helping potential Toller owners learn more about the breed.
 
Here's a link to the "Top 10 Reasons Not to Get a Toller"....they aren't bad things (in my opinion), but it is full of information and includes info about the breed that a lot of people prefer not to deal with in a dog:

A lot of my friend's have NSDTR - I see them a lot in agility and OB competitions in my area.  In fact, I only know 1 person who keeps their Toller strictly as a pet, which I think tells you how active they are and how much they enjoy having a job!!! 
 
They are very drivey and intelligent although I do find that they tend to be vocal (whining/barking) - particularly when bored/frustrated (too intelligent sometimes!) but also when left alone.

I forgot to mention that. Tollers do tend to be fairly vocal dogs, some worse than others. The ones I know aren't really barky, but they do whine quite a bit and tend to make sort of moaning noises often when they're bored or frustrated, like you said. They also moan a lot even while sleeping. Sometimes I think they just like the sound of their own voice...lol.

I have a tollie and she is so different from my other dogs. SHE IS MY DOG.
She has the tollie scream that I had train out.  She works agility and is an eager competitor. She does have sebaceous cysts and a thyroid problem that is not uncommon to the breed.  She is not one that kids can come up to pet becaus she would rather chase a squirrel.
 A tollie will capture your heart and you will trust her. GO GET ONE.
 
love is all she has for me.
