Bee-have

Hello

Please could you tell me if bee/wasp stings are poisonous to dogs?

My Springer keeps chasing them round the garden and trying to eat them! I do tell her to leave them alone and she does, but if she does manage to catch one and it stings her, should I call the vet straight away? And is there anything I can keep in my first aid kit for her?

Thanks
