my jack russel did smethign like that- hes a fucking beast- he pulls us uphill on rollerblades and he only ways 16 punds
My old dog tanner used to bite his metal cage and tear holes in it. It got so bad to a point where he eventually made a hole for himself to crawl out of. Then we chained him inside the pen, he broke that too...
then he ran away and died.
my dog used to pull me on a sled down the road.
those wire leashes are crazy hard to snap. your dog is a tank
pretty cute too
