> went to see my whippet at only 3 weeks - and pregnant mum before that!!
Now my bitches re very sociable and love showing off their pups and having visitors.
I allow people to come whenever they want, but most come a fair way and are told that there's not a lot to see before 4 weeks.
I do no have worries about infection when they are young so much as my dog are off property all the time, and pups will have the benefit of full maternal antibody protection early on.
The socialisation of many different people coming to see them is good for them, especially as I no longer have young children at home and have to encourage friends and neighbours to bring theirs.
When my two were young there were always lot of people coming and going and pups have always been bomb proof an uber sociable.
I had one lady (who had owned several of the breed) fly down from Scotland before pups eyes were open as there was a cheap ticket. I also had a couple who came every fortnight from 5 days!!!
Those who have visited most tend to be the eons where the relationship with owners is closer, and become extended family.
