robbi you cant shoot a dog for chasing deer as it is not livestock they do not belong to anybody until they die and then become the property of the land owner in which they died on.
I do not agree with dogs chasing and all dogs should be under control, atb wayne ps here is the latest ho guidence
Dogs
14.60 Section 9 of the Animals Act 1971provides a defence for killing or injuring a dog if the defendant acted to protect livestock, and subsequently informs the police within forty-eight hours of the incident.
The defendant can only act in defence of livestock in such a way if the livestock, or the land on which it is, belongs to them or to any other person under
whose express or implied authority they are acting.
Note that the Animal Act 1971 does not extend to
Scotland
