I think Dawn is wonderful for about everything! But you can also get a product usually in the flooring section called Gum Out. It is a very small tube for getting bubble gum and sticky glue off laminate floors. Just takes a tiny spot, work it into the hair and it disolves it, but then a good shampoo is in order to make sure the gum out is gone. Worked well on my show yorkie who got it in the tips of her whole coat - uck, but the product didn't harm her coat in any way.
Love spring, but oak flower is starting and in everyones coats. What a mess and glad it is only for a few weeks. Our whole yard/cars are covered in a light yellow mist of it.
