Julia here - new to this forum, I have 4 Border Terriers and one Siberian cross. Hoping to share info and experiences with all of you. 
Hello Julie - welcome to the AADF forum. Sounds as if you have your hands full with five dogs to care for. I like Borders - super little terriers.
Hello and welcome Julie,
We met a boarder terrier on our walk this week. She was lovely and very friendly. My terrier does not generally like other dogs at first meeting but they got on fine.
All those active dogs must keep you very fit.
