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.
I do not recommend puppy parents to use this system unless the puppy is an apartment dog and will continue to use a potty station. It is recommended that when you first get your puppy at 8 weeks or older, you immediately begin the type of potty training that will be routine, i.e. outside. All dogs prefer to go outside.
