Thank you so much to those of you who are actually supporting my decision. And to those that do not, I totally understand why.. but at the same time its a puppy.. and it isn't his fault! Should we euthanize all puppymill dogs just because they are from a very undesirable place? Didn't think so. Like I said before if I didnt buy it, someone else would. And maybe that person wouldnt know about puppymills and not know what kind of conditions they have faced.
I am educated enough to know when a dog is sick. I have gone and played with him everyday for 3 days now. He plays and runs with the other puppies in the crate with him. He jumps. He plays and then randomly (and rather dramatically) topples over. He bites like regular puppies with those amazingly sharp teeth. I felt all over his body to make sure nothing felt weird and I checked in his ears to make sure he didn't have ear mites. I know I am no vet but I am taking him as soon as I get him tomorrow. (His appt is at 2:15) I got Roxie (my miniature dachshund) from a breeder and she had some infection that made her hair fall out and REALLY bad ear mites. I have not seen anything wrong with Oliver so I will assume for this rare circumstance he is healthy. He is current on all of his shots and will have a health guarantee. I wouldnt neceassarily say that puppies from breeders are any healthier than pet store dogs.. or at least in my case that is what happened.
For whoever asked how much I am paying for him... $400. I would never pay $600 or $900 or whatever you mentioned for a "mutt" (dont tell him I called him that!!).

I know they have Yorkie mixes on websites but I have never found one I love like this one. I walked in and immediately fell in love with this dog. I don't know what it was about him but I think he's great!
I don't remember if there were any other questions/comments I intended to answer but these are my thoughts for now. I will take pictures as soon as I get him tomorrow and post them right away. Yall will all fall in love with my *possible* puppymill boy!

I already got him a crate ready with tons of toys! All I need is the puppy now!
Oh and thank you so much to those who have offered advice about potty training. I think I am going to go with the crate training but take him outside all the time. And very excitedly scream "POTTY!!" everytime he's about to go. haha.
