Wet vs Dry food

It depends on how much wet food you're planning on giving and what quality it is.

Feeding only wet food is a disaster for their dental care. Most dogs only on wet food have huge plaque problems and their teeth look years older than they are. You'll have to be extremely consious of giving them hard chewy treats to help clean their teeth or get them professionally cleaned regularily.

A lot of the freely available cans of food aren't great quality so is the equivalent of feeding them mc donalds every day. Very tasty but not much nutritional value.

Mixing a small amount of wet food through his food wouldnt harm him if he got it occassionally but you'd run the risk of him not being interested in the dry food only if you mixed it through every day because the wet does taste far nicer for them. Also if you are going to mix wet food in regularily you'd probably have to look at using a mixer nugget rather than complete so the protein balance doesn't exceed what he should be getting. He's a newfie isn't he? Those who have giant breeds would be able to give you more info on that but that's my 2 cents worth anyway, if he's happy eating dry food then i'd leave him at it!

He's still a baby - give him a few weeks to get greedier and you won't have to worry about him getting bored with the dry food lol You could always mix in some veg? I try to stick with dry for our guy so it cleans his teeth and so he has nice firm poos but since he's been on crate rest I've started soaking some of the dry food in water and mashing it up to put in his kong to keep him busy - at least this way it's all the one brand of food so I don't have to worry about upset tummies!

Try mix a tin of tuna with sunflower oil thru it or raw egg will make it tasty.

Be wary of adding water to dry kibble. The ingredients in kibble can go off very quickly if it gets wet, so if you're wetting it and giving it to the dog immediately that's one thing, but I wouldn't wet kibble that'll be lying down all day.

I would definitely look into raw food for a Great Dane, even as one of his three puppy meals a day. I certainly don't have a giant breed dog, but I have a large breed (I have a bull arab) and at approaching 8 months he's a pleasant 25kgs and he's doing extremely well indeed on a raw diet. My pup was severely underweight when I got him, and I managed to get the weight on him and good condition into his skin and coat (he had ringworm and a wormy, wiry coat and bald knees and belly) - I used human-grade raw meat.

I started my guy on raw chicken necks, with fatty beef mince to help get the weight on him, plus some raw lamb or beef liver every other meal (not a lot of it though). As he's grown, he's graduated to chicken legs, lamb ribs, lamb necks and so on. Raised on mostly raw, he's used to dealing with bones and he takes his time and chews and crunches instead of gobbling and gulping. He has a magnificent head of white, white teeth (that's the 'bull' part of the bull arab - he's got a big set of landshark jaws on him) and his weight and his coat are good.

As summer's setting in here, I will feed dry food, but at the moment I feed Canidae, which is a higher-protein dry than you might want to use, but it's grain-free, which I like. He's not as fond of it as he is of his raw though!
