Alex is a keen dog admirer and over the years has had a number of dogs.
Alex has had an Alsatian, a Dalmatian, a Poodle, and a Great Dane, but not necessarily in that order.
Alex had Jamie first.
The Dalmatian was an adored pet before the Great Dane.
Sammy, the Alsatian, was the second dog Alex loved.
Whitney was owned before the Poodle.
Jimmy was not a Great Dane.
Can you match the dogs to their names and find the order in which Alex had them?

Hint
How many hands did the first person shake?
Answer
190.
The first person shook hands with 19 others, the second had already shook hands with the first and therefore shook 18 hands, etc:
19 + 18 + 17 + 16 + 15 + 14 + 13 + 12 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 190
