I have adopted both of my dogs from Mustardsandwich.net and never regretted it. They are definitely NOT a puppy mill. I did extensive research before I used them. They were professional, the fees were not out of line for what they deliver. They rescue entire litters of MIXED breed puppies. Puppy mills sell pedigreed dogs and "designer dogs" only. My puppies were healthy, socialized and calm. They were trained to follow off leash, potty trained and they were driven, not shipped, from S. Carolina to New Jersey. They spoke to me at length and interviewed me before I was allowed to purchase a puppy. They spent time teaching me how to calm them, gave me written instructions and answered questions months after I had them. Does this sound like a puppy mill? They are the best thing to come online for anyone wanting a quality puppy. They are responsible and dedicated. Anyone who thinks they are a puppy mill has no idea what they are all about.
