People who own puppy farm/mill rescue dogs!
A trainer here in Ireland is conducting a survey to find out more about puppy farm/puppy mill dogs -- she is hoping to see if she can pinpoint some of the training or behaviour issues people experience with such dogs, if any. It would be very helpful to her to get responses to a questionnaire she has created and as I know we have several people with cavaliers they know came from such backgrounds, maybe you'd be willing to help! The dogs can come from any location -- not just Ireland.
If people with such dogs PM me, I will send along the questionnaire which you can return to me or I will also give you Maureen's email-- then you can copy the PM'd questionnaire into an email, fill it out, and email it to her directly. I am just waiting to get her contact details.
