That's someone who cares- I wish everyone did this...& if pet stores are required to provide care sheets, private breeders should too. (& yes, I always did)
When we adopted our dog from a shelter I asked if they had any sort of care sheet. For instance a list of supplies you might need, etc... The shelter had been open for many years and has probably re-homed thousands of dogs and they just sort of stared at each other and said "that's a good idea, we should make something like that".
