When I set the winter growroom plants outside, my neighbor dog thought they were for him I guess. He bit two limbs off of my LSU Tiger and two off of two Valley Black. I stuck them in growbags with compost on the front porch and watered along with the cuttings in bags. They must have rooted because they're doing fine and growing. I intentionally pruned the top from Vasilika Sika, stuck it in a pot and covered it with a bucket for awhile and it's still just a green stem but no growth. Maybe I should have got the dog to slobber on it.
