I think it's worse when they DO listen!
A good friend at work was poised to buy an inexpensive golden for her daughter, from a dicey operation, no clearances, the sire was barely a year old, and the bitch wasn't much older and on her second litter.
As an example of what to look for, I showed her a flat-coat friend's litter listing, clearances and titles and pedigrees and every bell and whistle. Before I knew it, my friend decided she had to have the pricey flat-coat well above her (my, many folks')pay grade. Her daughter chipped in her birthday money and literally broke her piggy bank and rolled the quarters.
I wake up in the middle of the night sometimes, worried about that dog!
