This is the manner in which I was able to solve this riddle. It took me a while, but I am certain this is the only correct answer.

I drew a chart like this:

 House 1 House 2 House 3 House 4 House 5 Color Person Drink Smoke Pet

and also made a place for associations, those facts that are linked together but cannot yet go into the chart.

SO, the first time through the clues I came up with.

 House 1 House 2 House 3 House 4 House 5 Color Blue Person Norwegian Drink Milk Smoke Pet

 Along with the following direct associations: And with the following adjacent associations: Brit - Red House Swede - Dogs Dane - Tea Green House - Coffee Pall Mall - Birds Yellow House - Dunhill Blue-masters - Beer German - Prince Green House to left of White House Blends next to Cats Horse next to Dunhill Blends next to Water

So analyzing these facts we can see more associations:
1. House 3 CANNOT be Green since the owner drinks Milk, not Coffee.
2. Thus House 4 MUST be Green since it requires a house to the right. One which is White.
3. House 1 CANNOT be Red since the Norwegian lives there.

These facts limit the house color order to ONE possible solution.
Combined with the direct associations we have...

 House 1 House 2 House 3 House 4 House 5 Color Yellow Blue Red Green White Person Norwegian Brit Drink Milk Coffee Smoke Dunhill Pet

 Along with the following direct associations: And with the following adjacent associations: Swede - Dogs Dane - Tea German - Prince Pall Mall - Birds Blue-masters - Beer Blends next to Cats Horse next to Dunhill Blends next to Water

Now, looking for more limitations/associations we find that:
1. The Horse must be at House 2.
2. House 1 and 3 CANNOT have Birds or Dogs nor Pall Mall.
3. Either House 2 or 5 have the Blue-masters - Beer.
4. Since the horse is at House 2, then it must also have the Dane (the Swede has Dogs after all).

Our chart now looks like this, including the conditions "Dane - Tea" and "Swede - Dogs".

 House 1 House 2 House 3 House 4 House 5 Color Yellow Blue Red Green White Person Norwegian Dane Brit German Swede Drink Tea Milk Coffee Beer Smoke Dunhill Prince Blue-masters Pet Horse Dogs

Remaining limitations/conditions:
1. Pall Mall - Birds
2. Blends next to Cats
3. Blends next to Water.

The remaining analysis can now be made:
1. House 3 MUST have "Pall Mall - Birds".
2. "Blends next to Cats" can now only fit with Blends at House 2 and Cats at House 1.
3. The German is now the only one without a pet, therefore owns the fish.
4. Incidentally leaving the Water for the Norwegian.

 House 1 House 2 House 3 House 4 House 5 Color Yellow Blue Red Green White Person Norwegian Dane Brit GERMAN Swede Drink Water Tea Milk Coffee Beer Smoke Dunhill Blends Pall Mall Prince Blue-masters Pet Cats Horse Birds FISH Dogs

If you followed this analysis closely, you will see that this IS the only possible solution...well, except for this one.
