I bought Bandit from a "breeder" and before I had done the appropriate research. He was my first dog and first yorkie. He came home before twelve weeks (around 9.5 weeks). when we went to pick him up we were not allowed inside and all to dogs were throwing up which was "due to the heat" (since I never owned a dog I believed him). I never saw Bandit walk because the man was holding him and handed him to me so I never saw him walk, so I never saw how lethargic he was. Before we left the man yanked open his jaw causing Bandit to yelp to jam Nutrical in his mouth (which he always just licks off our finger) and to shove a quarter of a huge Vitamin C down his throat which I'm surprised he didn't choke on because he had a "cold." When we took him to the emergency vet that night (our vet apt was scheduled for the next Monday, 48 hours later) because Bandit wouldn't eat or drink and was incredibly lethargic, as well as the following night, we found out he had a variety of parasites including coccidia and a kind of worm and viruses. When we finally made it to the vet that Monday he had kennel cough as well. Now while I accept responsibility as being uninformed as a buyer, I do also blame that beeder for selling him to me too early, selling to me knowing that he was sick and not informing me, and then yelling at me and insulting me (I have emails as proof) when I told him about the varying ailments he sold Bandit to us with.
When we bout Nala exactly a week ago we found a much better breeder, and she came to us without a single parasite or anything
She was sold to us exactly one day before 12 weeks and UTD on all age appropriate shots.
I hope that breeder is held responsible for selling that puppy wayyy too early, but as I learned as a buyer, you need to be informed about what you are buying.
