The poor other dog just can't keep up. They still amaze me every-time I see them move. They are amazing athletes
you would think they don't have a chance with a Large dog, but your wrong. They over whelm them, circling, jumping, ducking & dodging till they can grab them by the neck for the take down.
We met a poor Burmese Mountain Dog once, they sniffed each other (mines a male / hers a female) then my dog gets the crazy notion to play and literally jumps on the back of the mountain dog and starts wrangling it's neck & fur, while play growling.
The poor Mountain dog freaked out and just kind of threw him off her back then rolled over in submission. He sniffed her then completely ignored her.
The owner just gave a look like "what's wrong with your dog"?
Jack is great dog.
