The surprising factors are where Europe lies on this trend line. Basically even though middle European countries are highly developed they have a very low dog search numbers. All of the countries are bunched together off of the trend line and where their wealth would predict that they should be.
Then next bunch of countries are all very similarly located on the trend line with USA, Canada and Australia having near 1.5 dog searches per person per month. These countries have many dogs and areas where dogs can play.
The biggest surprise is that Ireland has nearly 3 searches per month (double that of America) and the UK has by far the biggest interest in dogs with a rating of around 3 and one half searches per person per month.
There are many conclusions that can be drawn from this data. It appears that a countries wealth per person has a lot to do with its peoples desire to search for dogs, and maybe own dogs. While Europe is known as a dog loving region, its cold temperatures and often small apartments in the cities may limit the amount of dogs and dog interest that these sophisticated cities have.
