I am an Accredited Breeder as defined by the kennel Club, I bred a litter of Chocolate labs back in Feb so I hope I can offer you some sound advice. Dean who sells the Bean Bags was a regular visitor to my house and he can vouch for me.
I actually "interviewed" potential owners of our puppies and was very rigorous, I turned many people away who thought they would be the perfect owner.
My first bit of advice is not to buy the puppy as a Christmas present, try to take that out of your mind buy the pup as a family pet as and when its ready to be picked up.
Have you enquired about medical certificates to your breeder? Make sure you get to see Hip scores and eye tests results (eyes must be tested every year) Just because a breeder says a puppy is KC registered, doesn't mean it really is so physically ring the Kennel Club to verify. Ask questions about the parents, ask about their history, ask about the breeding lines of the sire and if you can, get over and see him.
The last thing you want is to take a puppy home and a few weeks down the line something goes wrong, all it takes is a few hours for you all to fall head over heels in love with him/her and to loose a pup at an early age can be devastating.
You should absolutely, 100%, definitely, take the kids to see the pup before you take him/her home, as a breeder I would have turned you away had you not done that. Sounds harsh but why I insisted on it was I wanted to see how the kids behave and how the parents react to the kids. If I thought parents couldn't control their kids, it was a good pointer that they wouldn't be able to control a 6 stone Labrador wanting to pull them across the park on a rainy day.
Its a very big commitment buying a pup, and too many pups are ending up in rescue centres and the number is unfortunately growing by the day.
This is a commitment that will change how you live your lives for the nex 14 years. Holidays have to be planned, even going out for the day has to either include the dog, have a dog sitter or you don't go out.
Hope I haven't gone on too much but I wanted to draw your attention to a couple of things that are really important.
If you need any advice I would be happy to answer any thing you may want to ask.
You can see Milly's puppies on her website below! I am pleased to report all puppies are doing well. One now lives in the USA and one lives in Germany. My daughter had one as a kind of wedding gift and I beg her all the time to let me have him back, he is just gorgeous and I love him to bits, He's the one called Monty!
