Can dogs get stung by nettles?! Since our walk Dixie has been holding her paw oddly and keeps suddenly licking it. I have had a really good look, there is nothing there, I run my nail down all over to check for tiny thorns, nothing, checked between her toes and pads, nothing. She wont walk on it right and keeps stopping to lick it, then looking at me to say help! What can it be? What should I do?!
