p.s. Further to the above, this is part of a quote from BHPS re. dogs and hedgehogs.
Otherwise, training the dog to leave hedgehogs alone is the ideal solution, taking the dog out for its ‘after dark’ run in the garden on a lead, using a muzzle and making lots of noise before the dog goes out to warn the hedgehog something is happening can help. Hedgehogs often have a routine so if you see a hedgehog about at a certain time it is likely to be around near that time the next night – avoid letting the dog out at those times.
I know some people are reluctant to use muzzles on their dogs, but some dogs apparently don’t seem to mind them and it isn’t as if they would be wanting to chase a ball, etc. at night, I imagine.
