The word "goose" comes into English from an ancient Germanic language that had something called strong declension. Basically, what it means is that these words, which include "foot" and "tooth," pluralize by changing the "oo" to "ee" (like foot/feet and tooth/teeth). So that's why the plural of "goose" is "geese." Similar rules come into play for the words "louse" and "mouse." While people may have used a word similar to "hide" as the plural form of "house," the word was simply modernized into the more standard form of English pluralization (addition of the letter -s) while the others were not. "Moose" comes into English from a North American/Native American source around 400 years ago and does not follow the ancient Germanic language rules. The similarities between the two words is simply coincidental.
