A few weeks later, there won't be any small dog breeds left anymore, big dogs will gather in packs and hunt down smaller breeds.
About 1 month after we disappear, all cooling water I'm nuclear power stations will evaporate. This will lead to serious explosions much stronger than Hiroshima and Chernobyl disasters. Billions of animals will die of cancer, but overall the planet will recover from the radioactive contamination rather fast and easily.
1 year after we disappear strange stars will stars will start to fall from the sky. During our space history we took thousands of objects to our earths orbit. The highest satellites will fall after many years.
After 25 years all roads and side walks will be covered in vegetation. Where there are plants there are herbivorous animals and where there is prey there is always a predator. The surviving dogs will cross with the wolves that come to the form of cities. Without us the air will become much cleaner, In some cities the visibility range will become several times longer, cities like Dubai and Las Vegas will be buried in sand. The desert will take what belongs to it, so will all of nature.
