I am so sorry
this has been very traumatic for you I am sure and all you wanted was a healthy happy pup and took two babies home to give them a good home and this is what happens. Petland should be ashamed as well as puppy mill breeder - this is horrific and it is so sad as they do not care how it affects people emotionally selling a sick puppy to a couple so excited about getting a new pup and then their world is turned upside down in the matter of days like yours has been. This is so wrong I just will never understand this all - the only thing i can say is he knew someone loved him before he left this world and someone who cared for him and tried to do what was best for him. I hope your other baby stays healthy and brings you all the joy you were hoping for in getting a little puppy and that this whole nightmare will be behind you soon.
