Cat vs. Dog vs. Horse in the US, the UK, Brazil, Japan and India

Today, a face-off between the three animals that are the most closely associated with humans since ancient times: cat, dog and horse. However, instead of the usual worldwide comparison, Google Trends also allows for zooming in on specific countries' search patterns. For starters, let's see what this gives for the US:

cat 0.48
dog 1.00
horse 0.41

In the US, dog is twice as popular as the other two. Cat barely beats horse. How about the UK?

cat 0.63
dog 1.00
horse 0.85

Lo and behold, horse is more Google-popular than cat in the UK! How about Brazil?

cat 0.92
dog 1.00
horse 0.53

Through the four years, from a basically equal position horse declined in popularity while the stable dog at most has a slight edge over cat. Maybe Japan looks different too?

Yes! Japan is most interested in neko a.k.a. cat. Last but not least [cliché alert], it's India's turn:

cat 1.00
dog 0.50
horse 0.30

Cat also dominates in India and what's more, it has an impressive seasonal peak at about New Year's. Surely, there must be an explanation : can anyone help me out?
