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.
Socialization should begin as soon as you get your puppy and often this means at 7 weeks of age. Puppies naturally accept new people, other species and introduction to new situations during the socialization period which occurs between 7 and 14 to 16 weeks of age.
