I thought of something else REALLY COOL and unique about tinies!!!!
Thery cause less damage! I mean when Chai scratches at the door, it doesn't even make marks. When they poo, it is soooo small that it is like rabbit droppings and when they pee it is only like a teaspoon!!
As compared to my 18 lb westie and my standard poodle who can pee a lake...these little guys are so easy to clean up after!!!
