I'm so sorry you're going through this stressful situation. The breeder never should have let the pup go so early. I think you have look at it as if he is a premature baby. Premmies always need special attention. I pray he will continue to grow and do well. You are being a great Mom to him. You want him to live, get stronger and to do well. I'm sorry some people don't understand that. Keep up the good work.
