Puddin is soooo precious! I love the puppy pics! I miss my boys as pups like that!
Wish I knew more about the vacs and the amounts to help you out. It does seem odd to give a 3lb dog the same amount as an 1100lb horse...
My boys were 2.2lbs at 12 weeks and in the end after all the growth spurts, they ended up one at 9lbs and one at 5.5lbs... so you just don't know what you'll end up with!
