According to Euromonitor International, eight of the 10 countries that spend the most money on dog food are in located in Europe, with Norwegians ranking as number one.

People in Norway spend the equivalent of US$639 per year, per dog on petfood, which is nearly 50 percent more than second-place Switzerland. Norwegians are trading up to premium products, purchasing higher-priced organic and "diet" dog foods, which sometimes also come in costlier meal-size packages instead of larger bags.

In contrast, Euromonitor found that Vietnam spends the least on petfood, the equivalent of US$0.75 per dog, which is attributed to the fact that in poorer countries, such as this, dogs are often still fed table scraps instead of petfood.
