Damien was trying his best not to go for the kill despite what his instincts wanted of him when he considered the Cursed One his prey. But he had to hold on. To make himself seem like the threat and keep it's attention on him. 

Damien then wrapped an arm around it's neck to the best of his abilities as he twisted himself and unlocked his toothy hold on the wolf. His attempt was to help wear the wolf out by now the means of choking the wolf to slow it down and not kill it. He would hold on the best he could while arms were locked in a choke hold.
