...is actually a toddler's brush. Bright green with sparkles and a small head to fit in her mouth. So far we've used it twice and she is 9 1/2 weeks old. She is fascinated by my electric toothbrush, and apparently liked the smell of the dog toothpaste I showed to her. It was an easy matter to put the paste on the brush that I told her was her own.... She is a very inquisitive and adventurous dog, not timid or shy at all. That is going to make her precocious in some ways, but she will need a firm hand in other matters!
