Kingda Ka became the tallest and fastest roller coaster in the world, taking both world records from Top Thrill Dragster at Cedar Point. It lost the title of world's fastest when Formula Rossa at Ferrari World opened in November 2010.
I want to know as much information as I can about puppies, since we'll be fostering pretty soon. Someone said (not on Dogster) that they should start wearing breakaway collars at 4 weeks.
It depends on the puppy, but generally puppies should be able to start running once they are between 8 and 12 months old. For larger and giant breeds, you may want to wait until they are 18 months, which is the age thrown around the most online.
