We have had pimmsdog for 15months now, he is just over 2 and we are over all the issues we had when we first rescued him. He is now an adorable, reliable family member who loves the DC and DH. We have learnt that although he looks more like a black lab he has a LOT of collie in him and behaves like a proper sheep dog herding up the DC back to us when we call for them. We have mastered recall, walking nicely on the lead, fetch, drop, stay and no longer bin dive with the help of some duck tape on the bin lid 
We have been thinking about getting pimmsdog a friend for some time now, knew we wanted something with collie in but was unsure what mix we would get.
We are going tomorrow to look, make sure the DC and pimmsdog are ok with bring home as I will fall in love with a springer collie cross a "sprollie" to go with our "lollie" 
Am I totally mad? The DC finish school tomorrow morning and then I will have 9 weeks of 4DC, pimmsdog and a new puppy
