Wet food is 'commonly' made up of 80% water and your dogs poops will be sloppier and smellier than if just feeding a high quality dry kibble (I am talking cheap supermarket canned food, not the food Amanda is speaking from in the above post, which is DEFINATELY NOT CHEAP and of a good standard).
You can let the kibble soak in chicken broth, you will see the kibble expand (as it does in their tummy's) the kibble will have soaked in the flavour of the chicken broth to make it a little more appealing.
Perservere with the yoghurt, its good for your dog. My Jett licked the yoghurt off the kibble to start with, now she can eat it alone without any problem at all. Rather than feed canned wet food why not feed raw meat......try mixing some raw meat with the yoghurt and kibble....get seome ground up beaf or lamb or kangaroo (or whatever kind of meats you guys have there) and stir it all together. Your dog will soon get used to the kibble.
You can also try some cottage cheese with the kibble as well (low salt), sardines, vegetables (Jett LOVES her vegies), i just add in some of the nights leftovers for her as she eats after we do and pretty much gets anything that is left over, apart from the cooked bones). Chicken necks and chicken carcus (whole or ground) are also a favourite of the dogs, they go NUTS for them!!!)
Just think of the puppy as a baby who you are feeding solids to for the first time

only you dont end up wearing it! The puppy, like a baby, will develop a taste for what you are feeding it. A dog will eat anything if its hungry (Jett used to eat horse poop

). Take the food away and toss it after 10 minutes, a puppy should have gobbled it up and licked the bowl clean by that time.
Good luck it wont take long to have him licking that bowl clean of all the kibble.
