Stephanie and Marcus are going to Michigan to do some camping and have asked Nikki and I to watch Braxton. We agreed and picked him up on Wednesday as tomorrow, Thursday, we have to drive up to Kent State to pick up Jonny. I went from work to meet Stephanie to pick him up as that was going to save me an extra hour of driving. When I got home Zoey and Penny were so surprised and happy to see him. The dogs all played well, but Penny had to be put away a couple of times because when she is done playing Braxton just keeps trying to harass her into playing more and Penny shows her teeth and growls. We don’t know how far Penny would go, but never want it to go beyond that anyway. After a bit of rest Penny is usually ready to play with him again for a while.

All the dogs have gotten along great. Both of our dogs play with Braxton and sometimes they are both against him, but they are all having fun and he is so quick he can fend them both off at the same time. Nikki and I just sit and watch them play and its very entertaining. Braxton is a runner, so we have had to keep him on a leash every time he goes out. Stephanie left a 30 foot training leash and I have been able to let all the dogs out and tether Penny and Braxton together. Penny and Braxton both understand and happily walk around together. There are times when Penny lays down and when Braxton gets near the end of his leash she gets up and walks around with him. She wanted to come in house once and it turned into a tug of war and she pulled him closed enough to the house where she could lay down and “keep an eye” on him.
