How short should they be...?
I ask because my girl frequently damages hers, I don't think they are particularly long.
After the most recent incident where she once again snapped one right through the quick close to her leg leaving a tiny, black, bloody stump I asked the vet to remove them but then read about how doing so causes later arthritis, dogs use them etc etc decided against it.
I have been filing the stump nail daily to keep it mega short and am just waiting for her to snap the other one when her normal walks resume 
How short do I need to keep them to stop her injuring herself?
Or should I bite the bullet and just get them removed...
