A couple days ago I posted a new photo of Cutter, this is his sister Hope. She and Cutter are the 'mature' dogs here, both 11 years this Spring. I find the breed generally ages amazingly well, you wouldn't know either of these dogs were eleven. In my experience the cross over age from prime to geriatric is year twelve to thirteen. This is when you will realize that they are aging, if you don't have any serious health issues at this time then they usually enjoy a good and spritly old age, if health issues start to flare up it may be a sign that they are going to have difficulty in their final years. I have my fingers crossed for Hope and Cutter who right now are in excellent health.
