Thanks everyone for your help concerning Seren's torn dew claw. We've just returned from the vet. It wasn't her toe just the nail. Her nail was trimed (pretty deep) and bandaged.She looks so pathetic holding her foot up with the bandage. Hopefully the bandage will stay on at least until tomorrow. A little bit of 'bitter apple' may help. The vet assures me she will be fine.
The Basenji Forums folks are the best!
