We were introduced to the breeder by one of the big names in the breed club for that breed who is well known for producing excellent lines, so I have no reason to doubt that them. They are a hobby breeder though, so don't consistently breed all the time.
Both mum and dad are KC registered and have obviously had all the relevant health tests for the breed.
Pups are around 4/5 weeks old and so far all I've had are a couple of phone conversations (instigated by me) and a couple of pictures.
I don't know what the right amount of contact to have with a breeder is. I don't know if I'm being too pushy requesting a picture a week or if I've engaged with them too early? Some guidance on this would be greatly appreciated!
