Poodles are a group of a formal dog breeds, the Standard Poodle, Miniature Poodle and Toy Poodle. The height of a standard poodle is typically between 18 and 24 inches, although being over 15 inches specifically is what sets the standard poodle apart from miniature and toy poodles.
The Chihuahua is the smallest breed of dog, and is named after the Mexican state of Chihuahua. There are two varieties of Chihuahua - the Smooth Coat (smooth-haired) and the Long Coat (long-haired). Both the Smooth and Long Coats have their special attractions and are equally easy to keep clean and well-groomed.
A tabby is any domestic cat (Felis catus) with a distinctive 'M' shaped marking on its forehead, striped by its eyes and across its cheeks, along its back, and around its legs and tail, and (differing by tabby type), characteristic striped, dotted, lined, flecked, banded or swirled patterns on the body-neck, shoulders, sides, flanks, chest and abdomen. "Tabby" is not a breed of cat but a coat type seen in almost all genetic lines of domestic cats, regardless of status.
A calico cat is a domestic cat of any breed with a tri-color coat. The calico cat is mostly commonly thought of as being typically 25% to 75% white with large orange and black patches (or sometimes cream and grey patches); however, the calico cat can have any three colors in its pattern. They are almost exclusively female except under rare genetic conditions. Calico is not to be confused with a tortoiseshell, which has a mostly mottled coat of black/orange or grey/cream with relatively few to no white markings.
