Be prepared for things to get even more challenging. German shepherds are big dogs and they become large quite quickly. However, they are mentally puppies until they are two or three years old. You can't expect him to act like an adult dog. And some time between about 6 months and two years all dogs go through adolescence. During adolescence dogs will test their boundaries and seem to forget all training. How long this obnoxious "butt-head" stage lasts depends on the individual dog. For some dogs it can be the entire duration of adolescence (up to two years), for others it might only last a few weeks or days. The severity of a dog's "misbehavior" also depends on the individual dog. Some dogs are holy terrors during adolescence while others' misbehavior consists mostly of thinking for an extra long time before deciding to follow a command. Ask your trainer for advice in this situation. If you do not already have a trainer then I cannot recommend enough that you get one since you have two very young children in the house.
"I've got the blues" Originating in the mid-19th century in southern United States, an early form of blues music developed from the songs of African Americans, sung while they were working in the fields, known as "work songs", "shouts" or "field holler". Although at first this music was limited to singing only, instrumental accompaniment came later, often with a guitar or harmonica. However, the blues are not only attributed to African-American music. In fact, elements of European and Caribbean music can be found within this genre. Later on, country songs and pop music also helped make the blues popular. As social changes in the 1950s and 1960s occurred, the blues changed. Radio DJs began to play the latest, electric blues songs, reaching a younger generation. Led Zeppelin, Jimi Hendrix, The Rolling Stones and many rock bands were influenced by both the acoustic and electric blues styles. Today the modern blues experience is entirely independent from the color of its performers' skin.
