A friend has just lost his dad and would like me to have his colliex dog now he thinks its a first cross but my other friend says you would be able to tell if it was a first cross and he thinks its not and what exactly does 3/4 1/4 1/2 crosses actually mean sorry for not understanding. He is a good worker but have heard that first crosses are not very good could you tell just by looking at the dog? If so whats your opinion this is him anyway.
Thanks
