In some ways they are easier now, but they still play together like puppies. I think at 18 months they are still puppies. When they are in the playpen, they make little nests on the edges to sun in or stay warm, when cooler, but lot's of time they just play and chew on bones and such. They have toys in there as well as in the house and they play with their toys especially tuggie ones. They love to play tuggie inside and outside. They also love to chase each other around things...the center bales in the playpen as they have made a "Bristol" high banked track, and in the house around the sofa and dining room table in the great room. Each and every morning and especially in the evening they chase each other around and around and then the chaser switches and the other one chases, the chaser barking the whole time. When that's over they wrestle and have fun in general. In the evenings after their walk, my girl Cecil loves to chase her tail and will spin until I am sure she is dizzy. They are fun to take on walks, but I still can't take both together. I take one in one direction and Richard heads out in the other. We do a mile in the morning when they first get up or I wake them up and one in the evening around 5-5:30. And they still have to have the evening chase. Very often I do two in morning and two at night as Richard often begs off for one reason or another....He misses out on the fun. Each dog generally gets to socialize either with another dog on a walk, or in a yard or with another person or two. Everyone loves the girls....very social and love to kiss. I can't get as long a work day as I wish as my day can't begin until they are in the playpen or in their room for their 1PM nap. And then around 4:30 it's time for the social time start up with the girls. They aren't nearly as destructive and I can generally leave them alone in the house for up to 20 minutes without worry. They go to bed at 7 in their kennels, but take their aftenoon nap on their dog beds in their room outside the kennel. It did not work at all for night sleeping outside the kennel on the dog beds. They sleep 12 hours or so. Great girls. Thanks for asking....Sorry I talked on so long.
