THREE:Frederick was very fond of dogs. This was one of his earliest passions, and it continued until the end of his life. He almost invariably had five or six Italian greyhounds about him, leaping upon the chairs, and sleeping upon the sofas in his room. Dr. Zimmermann describes them as placed on blue satin chairs and couches near the king��s arm-chair, and says that when Frederick, during his last illness, used to sit on his terrace at Sans Souci in order to enjoy the sun, a chair was always placed by his side, which was occupied by one of his dogs. He fed them himself, took the greatest possible care of them when they were sick, and when they died buried them in the gardens of Sans Souci. The568 traveler may still see their tombs��flat stones with the names of the dogs beneath engraved upon them��at each end of the terrace of Sans Souci, in front of the palace.21 Sophie Dorothee was a very pretty child. The plan was probably already contemplated by the parents that the two should be married in due time. Soon after this Frederick William lost his mother, and with her all of a mother��s care and gentle influences. Her place was taken by a step-mother, whose peevishness and irritability soon developed into maniacal insanity. When Frederick William was eighteen years of age he was allowed to choose between three princesses for his wife. He took his pretty cousin, Sophie Dorothee. They were married with great pomp on the 28th of November, 1706.
