I cannot speak about yours or your friend's experiences, however, if you would take a moment to research common ailments in Yorkies and toy dogs, you would find that MVD is quite common among Yorkies.
JaLa's Garden Yorkies - Health Concerns of the Yorkshire Terrier
If you take a little time to read this, it is easy to understand why Yorkies can become ill quite easily. Illnesses are often undectable during initial examinations.
So when I was looking into purchasing a toy breed, and I chose a Yorkie, my research told me that this was a possiblity. That does not mean that the breeder bears no responsibility, but in this case we are talking about hearsay.
I chose not to respond to Mr. Glass, since his condascending nature leads me to believe that he is only seeking to destroy rather than to help.
I can tell you from my experiences with Denise Ronayne and her husband Jack that they have a very lovely house that provides a safe and comfortable home to sires and dams. I have seen mothers nursing babies in a room off to the side of their kitchen. I was not allowed to enter, for obvious reasons and completely respect the nature of her business and the mothers' desire to protect her young.
Those of you who have happy and healthy companions purchased from Denise should not feel foolish. You should feel fortunate, as I do, that you have a beautiful friend and cuddler who loves you as unconditionally as you could ever dream.
I do not wish to stir up anyone or raise a fuss. My intention was to share my own experience, as it has been a very positive one. I am FAR from a fool and am smart enough to know who the real wolf is, Mr. Glass.
