This would probably have been best posted in the Traveling With Pets forum.

Seeing its here I do agree with the sentiments of mezza's post, you get what you pay for.

We've found the Black Hawk range to be very good.

Here's a link to dry dog food reviews of products available in Australia. http://thegreynomads.activeboard.com/t64530912/i-think-it-was-missed-before/

I am very hesitant to weigh into this issue as what to feed your dog is a very contentious issue amongst many pet owners. I'm sure many will attempt to debunk what I have to say.

I will however take the plunge as I have been a member of this forum for many years and have learnt more here than any other single source. Since I'm not actually on the road yet I have very few opportunities to pay the members/Forum back as I have zero practical experience in GN'ing to offer in return.  

This topic however, is one I can help in so I feel compelled to try.

By way of introduction I was/am the co-founder of the MDBA ( https://www.mdba.net.au/ ) I'm no longer involved with them in any way but my original business partner is and I'm still in touch with her regularly. My own actual speciality was canine genetics. Specifically, the genetics involved is the selection of breeding dogs to remove or enhance specific target traits. 
My partner, Julie's speciality was canine nutrition. She studied directing under Dr Ian Billinghurst who was one of the MDBA's original patrons.
My knowledge of canine nutrition is therefore not as great as hers but still well above average. I studied under her.

In a nutshell 99% of commercial dog foods are totally unsuitable for your average pet dog. Some are downright harmful and no, I won't name those ones. The average lifespan of a pet dog was significantly higher than today up until approx the 1960's when the first commercially successful dog food food was introduced in the USA. The ACTUAL first goes back to the late 19th century but for all practical purposes did not become widespread until Kibble started production. 

Since then, various health issues slowly started to appear and have gotten progressively worse. (Not unlike our own human diets actually) Up until the 1960's dogs were almost universally fed a raw meaty bone every day, usually free from the butcher, and whatever was left over from the family meal. That's it. No fancy diets, and very few, if any real health issues.

This rule of thumb still applies today with the caveat to remove any member of the onion family and any cooked bones.

To summarise everything here would involved writing a book so I'll just list some key points to try to explain the digestive process of a dog.

1. Raw food only. Cooking doesn't harm the food per se but removes a lot of the nutrients. No wolf owns a cooker. Factious I know but illustrates a point. And a wolf has identical requirements to a Chihuahua.

2. Dogs CANNOT process cellulose. Therefore, any raw vegetable eaten will reappear out the rear in much the same way it entered. Cooking breaks down the cellulose and makes it digestible but also takes away most of the goodness. A sure way to overcome this is to put raw vegetables through a blender first. 
In the wild, a dog will get it's required vegetable intake from the stomach contents of it's prey where it has been masticated by that animals molars (Which dogs don't have which blows the theory of them being omnivorous)  and partially digested.

3. A dog needs more than just muscle meat. In the wild, a dog will consume the internal organs first and requires the nutrients contained there just as much, if not more than the actual muscle meat.

Let's translate and summarise that info to today's domestic dogs and our own lifestyles and in particular the lifestyle of nomads on the road.

a. Raw meaty bones daily are still your best bet to start with. Note' MEATY bones.

b. The leftovers of whatever you've cooked that night. With the caveat previously mentioned.

c. Pet mince from the chicken shop. This is the entire carcass of the chicken ground up so it has the phosphorous from the meat and sinews etc and the calcium from the bones. If you add a heaped tablespoon each of brewers yeast and kelp to every kilogram that will help. Also a few tins of canned sardines and some vitamised raw veggies and a several raw eggs, including the shells. This can be mixed up in advance and separated into portions and frozen if you have the freezer capacity. This was how in fact we fed our own breeding dogs back in the day. 

d. A viable alternative to this if freezer space is at a premium is a commercial product called Natures Gift. I've visited the factory and can tell you it's all natural good food like you would serve your family. Yes, it is cooked. That's the compromise you must accept. But, being cooked in the can negates any need for the preservatives usually used. They also add natural additions such as garlic. 

c. On a weekly basis at least add some offal. Kidneys, heart, brain etc

On the subject of feeding your dog only what we would eat ourselves, I very respectfully point out they are not humans. Dogs will for example eat their's and other animals faeces. Not something you would feed your family but sometimes needed in a dog. You will no doubt find they also often seem to prefer a muddy puddle over the changed daily, fresh clean water you provide for them back home. You may find it disgusting but your dog doesn't.

I'm happy to field any questions members may have and I'll do my best to answer. Please remember however it has been many years since I was actually involved in this field and even in my own primary field of the study of genetics my memories are failing never mind a secondary field such as this. 

If I don't know the answer I will however ask Julie at the MDBA. If your question requires a conversation I'll ask if she is happy to receive emails direct from you. The MDBA is not solely about breeders. They also nurture responsible pet ownership.

Cheers

Jim
