Re: Wolves may be preferable to the hunt...
Its probably far too late to prosecute now but you have a claim under Dogs (Protection of Livestock) Act 1953 http://www.legislation.gov.uk/ukpga/Eliz2/1-2/28
For the purposes of this Act worrying livestock means—
(a)attacking livestock, or
(b)chasing livestock in such a way as may reasonably be expected to cause injury or suffering to the livestock or, in the case of females, abortion, or loss of or diminution in their produce.
(c)being at large (that is to say not on a lead or otherwise under close control) in a field or enclosure in which there are sheep
There is a clause that c doesn't apply to packs of hounds but sections a and b still apply to them.
