It might also be a bit of a portmanteau with a second reference to dogpile.com which was a pre-Google "search engine" that compiled search results from multiple search engines. Back in the day you often had to separately search altavista.com, lycos.com, askjeeves.com, yahoo.com, etc. because some of them would work for your query but others would not and it was difficult to predict the performance of any particular search engine, but usually at least one of them would have the result you wanted/needed.
Dogpile was an automated way to search all of the search engines at the same time with one query.
