There are four rationals for a merge Duplicate in this instance one article is about a fictional character andor series another is about a dog actor in a similar way that Moose dog actor is different to Frasier Text Text is not an issue in either this article or the Lassie one Context Arguable but I believe that Pal does not need the information in the Lassie article to be notable on its own merit Overlap This is the only rational where there may be a case However the requirement on WikipediaMerging states that There are two or more pages on related subjects that have a large overlap Technically the Lassie article talks about Pal quite a bit in the lead paragraph in my opinion probably more than it should then under Dog Actors Pal is mentioned only in the first three paragraphs There is a large volume of information on the Pal article which is about Pal being Lassie however there is significant information that has nothing to do with Lassie and I feel would be inappropriate to place on a general Lassie page for instance the entire section on Pals death Having reviewed both articles side to side I think that there is a case to keep Pal as its own page  however it needs to be regraded as I dont think it fits as a GA status as it does not cover Pals life significantly outside playing Lassie and that the Pal article needs to be expanded to cover it as such
