I have a very strong dog that is highly reactive. There have been incidents of him getting loose and running out in the street. I am petrified of him pulling me down. I am so embarrassed of clinging to trees or mailboxes when something goes by. Everyone else I know can walk him okay. I use a cane and have a bad leg. This keeps us from getting exercise we both need. It's gotten so that if I see a car come around the corner, I panic. Now we walk out in the back field, where, ironically, I actually DID fall when I tripped on some tall grass. We have had trainers. I'm brave when someone else is around, but once I'm alone....
