Do westies have hair

All dogs eat grass from time to time; it's probably in part because of moisture on the grass, in part because they like the feel of the blades in their teeth (similar to dental floss), and in part it's because the roughage from grass is good for their digestion and elimination. Don't let dogs eat grass that has been treated to fertilizer or pesticide, but otherwise a small amount of grass eating isn't a problem at all.

They Somtimes Eat It If They Feel Sick.
