Penny is a high energy dog that needs room to run. Once shes gotten her daily exercise, shes pretty calm for the most part. We just moved across country into a tiny apartment so we no longer have a backyard for her to run in. Shes not adjusting well to the smaller accommodations but we are not in the position to move just yet. Shes great with cats, likes to lick them. Shes quick to run after other dogs but shes eager to meet them, not attack them. Shes VERY lovey, likes to rest her chin on you while sitting on the couch. She'll follow you where ever you go and makes a great watch dog. Shes great with kids as we have two young children and has never harmed them. because shes tall, she may seem intimidating at first.
