It is all find and dandy to advertise these dogs and breed them in the UK ... but what when the inevitable happens and DEFRA decide to do a raid, confiscate the dogs and then PTS them? Would not be prepared to openly flaunt these dogs if it were me, I couldn't cope with the possibility of losing them in such a dreadful fashion. Look what is happening to these poor illegally bred pitbulls, and the amount of dogs that are being handed in because of this 'amnesty', all of them will be killed because of the irresponsible actions of the people who bred them. At the moment anybody with a banned breed would be better off lying low and keeping extremely quiet.
I recently contacted DEFRA, they were aware of these dogs in the UK and seemed not too bothered about it as they only really consider 'Hybrid' wolves fromF1 crosses (which the czech is not one of).
