Overstimulated/crazy part way through walks -- help!
Hi. My Jack Russell-border collie cross sometimes goes crazy when we go on walks. Crazy looks like jumping up and mouthing my forearms very aggressively or snapping at my legs, clothing, back. It's quite random. Please help. I have been wearing long sleeves all week because Milo went crazy on me on Sunday. I took him for a walk in the fields near our house. There was no one around so I let him off of his leash. He had a great time. When I started to head back towards the path, he went crazy. I didn't touch him or try to put his leash back on.
I bring treats to try to lure him to a place where I can tie him up for a time out, if needed. Is this behaviour normal? Is there a way to figure out when or why these crazy attacks happen? They are scary as I can't seem to calm him down without a timeout. Thanks for your help. Heather
