I am having a bit of a litter reunion in a couple of weeks. All the pups are coming over with their new people friends for a play with their mum and brother. i am slightly nervous as to how mum will respond to this but can't wait to see how they have all come on 25 weeks now. Has anyone held or attended one before? How did mum and pups respond, did it go well? Anything i should know to manage it well?
