Does Snowball ever return to Animal Farm after Napoleon’s dogs chase him away?

Snowball never appears to return to Animal Farm. Squealer, however, claims that Snowball sneaks back onto the farm to commit sabotage. For example, when the first windmill falls down, Squealer claims that Snowball “has crept here under cover of night and destroyed our work of nearly a year.” Within a short time, “[w]henever anything went wrong [on the farm] it became usual to attribute it to Snowball.” In actuality, no one ever sees Snowball again once he leaves the farm.
