It was milk choc and we suspect only crumbs as my parents were looking after her at the time. I read that a small amount can make her restless and she does seem restless. As we are at the parents we aer 2 hours from our house so we can't call our vet. It was definately not a large dose though.
Thanks all (I would log in but can't remember the password etc when away from home)

Milk chocolate isn't the problem chocolate so she should be OK.  Bless, I know how hard the tempation can be to stay away from chocolate eggs :d

Hi Mollymoto,

I have replied to your other post and said that their is something you can get from health shops that vets use when dogs have eaten a lot of chocolate, now found the name it is Cal Carb and the quicker it is given it the better although if they have eaten paper or wrappers they will need the vet urgently.

If she has had only a few crumbs she should be fine.  Our dog has a bit of chocolate now and again and he is fine with it, although milk chocolate not dark.
