The reference to a Red Dog is likely to refer to the saying "seeing red", so yes a rabid animal can probably also be inferred just like Stags shed the velvet from their antlers exposing the bloodied red antlers at the start of the rutting season (a violent act to win over females) as seen here. https://www.mailonsunday.co.uk/news/article-6206553/Stunning-photos-deer-shedding-velvet-Alaska.html https://www.mailonsunday.co.uk/news/article-6206553/Stunning... Overall a red dog is almost likely to mean a dog that is angry for some reason.
