Yes I would start with what Chachi said. I had the bolting problem with 3 dogs
and yes at the same time. So I was constantly chasing dogs out my patio door. That all ended when I learned in obedience class the stay command. Heres how I was taught: 1. teach them to sit 2. teach stay 3. I use the word "free" as my release word. So they understand whatever I tell them to do they are not allowed to move until Mommy says "free". It has worked great
