What breed of dog was lassie?

Lassie was a collie. I found it interesting to learn that she was bred larger than the standard AKC collie intentionally in order to be able to look the right size as child actors grew taller. If you do want to get an AKC collie, it will be smaller and lighter than the Lassie you saw on TV.

The dog who originally played "Lassie" was a male Rough Coated Collie named "Pal" in the 1943 film "Lassie Come Home."

Pal's descendants continued to play the roles of the Lassie character throughout the television series for the 19 years it aired.

Lassie was a sable & white rough coat Collie. The 1st Lassie's real name was Pal & he acted in all the MGM Lassie movies before the television series aired. He also starred in the 1st 2 episodes of the television series & he was 14 yrs. old at that time. He was owned & trained by Rudd Weatherwax. All of his descendants played Lassie through out the entire series. Pal's great-great grandson, named Hey-Hey was the last one to play on the television series. I know you didn't ask for all this extra information so I apoligize for going on & on. I just happen to love Collies & have always had them as pets for the past 40 + years.
