CoNgRaTuLaTiOnS on your new puppy!!!! I'm sure you are just delighted.
On his water intake, these little guys are so tiny that they really don't need much water. If you are adding water to his food and/or if you are giving him canned food, then he should not need much more water than that. Adding some kyro syrup to his water will not only entice him to drink more, but it will also prevent him from getting low blood suger, which so many yorkie puppies under 12 weeks tend to experience. Just make sure he is eating regularly and eating well and he should be fine!!!!!!! GOOD LUCK with your new baby! Keep us updated on his progress.
Oh yeah, when do we get to see pics?!
