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.
Around 5 weeks old, your puppy will start to explore the area of your home outside of his nest box, so you'll need to supervise him and his littermates, according to the website of Austin, Texas. When he reaches 6 to 7 weeks of age, he'll be able to walk, run and play with confidence. Begin training your puppy to walk on a leash when he reaches 8 to 10 weeks of age. This is the age that you can safely separate a pup from his mom and littermates to rehome him, according to the Hartz website.
