Claws or Nails?

[kiaz1st]

I have three dogs, all of which I am constantly playfighting with (yes I am mad lol ) and all the time they always use their teeth, the only time I have ever seen one of my dogs use even their paws to attack was when it had bit onto my jumper and was using its paw to push it, but he was failing and it just looked like he was scratching. so even when I have seen a dog use its nails, it wasn't even on purpose. don't know who these people are, thinking that wolves have retractable claws, but yeah, probably little kids who don't want to learn of people older than them

Canines using nails doesn't bother me too much, even though it is far from realistic.

But you know what does bother me, canines having retractable claws. I always see people roleplaying wolves say things like "claws come out" or "retracts claws".
No No No No! Felines are the only animals that can retract their claws! Canines do not have retractable claws! That is one of my pet peeves.

I don't mind them using claws in fights that much, though.
