This is how I worked the claws:
Hope this make sense.
I found the middle st (where I wanted the bigger claw to be) in the 3rd row of the leg, and in the 3rd st to the right I worked:
Small claw: {ch 2, sc into 2nd ch from hook, ss into next base st},
Bigger claw: {ch 3, sc into 2nd ch from hook, hdc into 3rd ch from hook, skip a base st (middle st), ss in next base st},
And again small claw: {ch 2, sc into 2nd ch from hook, ss into next base st and fo}

I worked with a 5mm hook to make the claws of the back legs (same I used to crochet the whole thing, body, wings, etc) and changed to a 3 mm hook to make the claws of the front legs.

If you have any doubt about the claws, just ask me and I’ll try to help you as much and clearer as I can :). Also if you found another way to make them, please, let me know!

I love this pattern, it’s very clear. I frogged the old one because I wasn’t happy with the yarn, but this time I chose wisely and I’m loving it.
I mixed both yarns to make the spikes so everything is uniform.
Hmm I made the nostrils too … wide, but I don’t mind, I might make a couple of stitches to fix it. Also I’m thinking about crocheting claws instead of embroidering them to the legs.

Update: Well this is almost complete, I’m still kinda puzzled about the ears but I think I’m just over thinking it. As I said I crocheted some cute claws on his legs, it looks cuter now.
