* You had an Alsatian, a Dalmatian, a Poodle, and a Great Dane.
* Jamie was the first dog, and he was a Dalmatian.
* Sammy was the second dog.
* Whitney was a Poodle, and she was third.
* Jimmy was a Great Dane, and you're wondering if he was last.
Based on this, we can confirm the order:
1. Jamie (Dalmatian)
2. Sammy (unknown breed - we need more info to figure this out)
3. Whitney (Poodle)
4. Jimmy (Great Dane)
We don't have enough information to determine what breed Sammy was. To figure out the order of your dogs, we need to know what breed Sammy was.
