??? Poisonous plants to dogs

[estweyn 10]

I wonder if anyone knows if snow in summer which is out now (grey green leaf and white flowers) is poisonous to dogs. I have trawled the internet and cant find it listed as poisonous - the reason I ask is Josh keeps chewing at it. I know some plants are natural medicines for dogs but want to be on the safe side:)
