I was wondering if anyone had photos of the weaning pen or puppy pen setups you might be willing to share. we have a litter of 5 bully babies that are 3 1/2 weeks old now and I want to setup a weaning pen for them as they are now in a 4 x 4 whelping box . I have several things to use just unsure of best route to go. I have one of the sturdy black metal type ones on wheels that has the grate flooring with removable potty trays below and I also have a metal indoor/outdoor exercise pen. any suggestions or advice would be much appreciated .
