You know, I totally get the urge to dive into 'Mad Dog' without breaking the bank—I’ve been there with so many series myself! While I can’t point you to shady sites (those are a minefield of pop-ups and malware), I’d recommend checking out official platforms like Webtoon or Tapas first. Sometimes they offer free chapters or rotating promotions. Libraries also surprise me—many have digital manga/comic subscriptions like Hoopla.
If you’re dead-set on free options, try aggregator sites like MangaDex or Bato.to, but brace for inconsistent quality and missing chapters. Honestly, supporting the creators when you can makes a huge difference—maybe save up for a volume or two later? The art’s worth it!
