This heightens my suspicion that your dog is somehow based off of dinraal. First, there were all the general botw references, then you made that comment about how many crabs a dragon could eat, and dinraal is constantly getting shot at with arrows from link in order to get parts.
Using this knowledge, I have a few guesses about your pup.
First there's this one:

The reasons I think it could be this one are fairly obvious. The pup has the beginnings of horns and a long smooth tail. Additionally, the pup's eyes are blue with the red sclera, just like dinraal's. The colors aren't the same but they could change in the final stage, plus we know from past staff dogs that while they may be inspired by something, they're never replicas of their inspiration. The only thing I'm having a lot of trouble connecting is the bell, but, while this may be a stretch, when link shoots dinraal with an arrow, it makes a high pitched noise not all that different from a bell and the bell has a bright gleam on it like the gleam that appears when dinraal drops a scale.
Alternatively, it could also be this pup:

I don't have as solid of a reasoning for this pup but it does have similar eyes again and the coloring looks like embers/fire. Dinraal looks like it has fire in its horns and scales. The pup also has white toes that could maybe turn into claws at its final stage?
There are a couple other pups it could be but these are my most solid guesses for the moment.
