Amount of contact wished and provided are very personal decisions and could be discussed with the breeder beforehand if necessary. To be honest, I wanted a closer relationship with my Schnauzer's breeder than she provided...i.e. I would of loved for her to contact me and check in, however; that's not her personality, she has always responded to my concerns, has boarded Georgie (for a reasonable price), provided support and advice as needed. She actually runs a (closed) facebook group for all her "extended family" which has been another source of contact. But I think she's an amazing breeder and very knowledgeable. Someone perhaps that KazzyK810 would appreciate. So I think it might be part of your "shopping" when you are looking for a puppy.
What I did find interesting in the contract I signed was a clause that if ever my Mini was overweight, my Breeder would consider it "neglect" due to the propensity of Schnauzer issues associated with obesity...and she would have the right to "re-possess" my schnauzer. Now, in truth I don't know if that would even have been enforceable, however; I know it made me aware of everything my girl eats...and I've always made sure she never put on too much weight
