Which animal was largely supportive of Snowball's ideas before his expulsion?

Boxer, the hardworking horse in "Animal Farm," was largely supportive of Snowball's ideas before Snowball's expulsion from the farm. His character embodies dedication and a strong work ethic, and he believes in the principles of Animalism as promoted by Snowball. Boxer is depicted as loyal and willing to endorse Snowball’s plans, such as the windmill project, viewing these ideas as beneficial for the collective prosperity of the farm and a means to improve overall productivity.

Napoleon, Squealer, and the dogs were not supportive of Snowball's ideas. Napoleon had his own vision for the farm and was primarily focused on consolidating power. Squealer served to manipulate public perception and was more aligned with Napoleon's agenda, often using propaganda to undermine Snowball. The dogs acted as enforcers of Napoleon's authority, further contributing to the atmosphere of fear around dissenting opinions like those of Snowball. This context highlights Boxer's unique position among the animals as a staunch ally of Snowball before the political shift orchestrated by Napoleon.
