EtheringtonBrothers on Twitter/Deviantart has a bunch of resources for drawing a whole bunch of stuff, and some of those tutorials include anthro animals.
I'll be honest it's kind of hard to find decent tutorials for furries specifically. A lot of them feel like those "Draw exactly what I'm drawing" sorts instead of the "Here are a bunch of tools and how to use them" kind.
I would recommend broadening your resource hunt to things beyond just furries. It would be a good idea to look into art fundamentals. That way you actually have the tools to break down what you see on your own and apply it to what you want to draw, instead of relying on hard-to-come-by specialized tutorials.
Also if you want, you can attempt to draw a furry and post it, and I can see what needs improvement and send resources based on that.
