It is amazing how many well know show/breeder people that do not use contracts. I wonder why? Is it because they are soooo busy or they just don't have to? I will aways use contracts.
I use to have a shop in Dahlonega GA and had local crafts people have some of their things in my shop for consignment and realized later on it was best to use contracts. Why, because one person expected me to sell her things within a month and if no one bought I was suppose to buy all of her things. She got mad at me when I told her no - that is not how it works. If I had a contract - she would have remembered what I had said because it would have been in writing.
Just like selling or buying a pup - what are you wanting and what are you getting? If buying a pup under 6 months of age - there really can't be any guarantees as to what you are getting, because so much can change in those 3 months. I always sell under 6 months as companion pets, but do cover health guarantees. If you purchase 6 months or older - you have a better idea of what you are getting and the breeder can somewhat guarantee a bit better.
I bought a show prospect at 4 months years ago and she only grew to a small frame 4 pounds. Surprising to us, since she was the largest in the litter. Did I go back to the breeder and complain? No. I did go back to her and ask her if I could sell my pup from her, since I could not show or breed her and offered her back to her too. We both agreed I could sell her.
