Hi,
Just read your post and although I am sorry not to be able to help I just wanted to say thank god someone else is in the same position as me.
I have just posted a question that I hope will get answered as it is a minefield out there and I am so confused.I have driven the Cavalier Club puppy register people mad and they must be so sick of me and my questions.
Our little Cavalier died earlier this year at 6 from MVD and I am also trying to buy a really healthy puppy this time.
What a difficult job this is turning out to be.
The breeder I thought I had found with a suitable puppy has just shown me his breeding line and they link to my past dog's line, how random is that, so I am scared and think I am making a huge mistake so don't know whether to take him or leave him.
Awful decision.
