Oh dear, Bob is feeling very poorly 
and needs our help. He has gotten into the chocolate easter egg stash
. Looks like a trip to his vet. 
Here is some advice from Vets now 
and a video for all the family to watch Click Me. If you are concerned that your pet has eaten chocolate, you should call your vet; better to be safe.
Tips
– Never leave your dog unsupervised if something delicious and dangerous is in reach – Train your dog to ‘leave’ or ‘drop’ or ‘no’ giving you a chance to retrieve – Dog-proof bins are also available – Better to store chocolate in a high cupboard as they can open doors! – Dog gates are a great barrier but it doesn’t mean a tempting item can be left out as that temptation could be too much leading to injury – Not everyone knows chocolate is bad for dogs so let visitors, family and friends know
