Sometime Nigel gets white "spit foam" on the sides of his mouth when we're on a walk (especially when we're speed walking) or if he's out at the dog park playing hard. It usually happens pretty well into the walk and when it is warm out so I chalk it up to him being thirsty. He always takes a drink before and after we get home and never "foams" when he's just hanging around the house.
Animals can foam at the mouth for a number of reasons, excitement being one of them. They can also foam at the mouth from nausea or having a bad taste in their mouth. Since his foaming stopped after he drank, I would think he got a taste of something bad on the walk. However, if it happens again or he has difficulty swallowing or breathing definatley get him to your vet.
