Biggest mistake besides not seeing the dog in the woods is talking! don't talk, listen. (this advice works on most things in life) You call Joe Blow and tell him your looking for a dog. "What are you looking for?" well, i want a dog that does 500yd circles, checks in, bays loose, named charlie... "Man i got the dog for you!" ask him what he has BEFORE he knows what you want. But as with most things in life, people dont want to work, and i venture to say poundin the pavement looking for the dog you want is more work than hittin the woods and MAKING the dog you want...
10-4 on that...like ED said...keep your mouth shut and let them tell you what they have...that is no guarantee that it will save you some heartache but it is a good start...tell them what you are looking for and they will have it...
I learned that one years ago and that got be to breeding my own every chance I get...
I asked for a pup that would be about 55 pounds when grown with a decent ear length and by golly that is exactly what they had for sale...I ordered the pup and a year later that pup weighed about 25 pounds with a short ear...and didn't hunt the way I liked...
