Oh ok..
In real, practical terms, not 'give me the needle I'll do it' because you can't unless you're a vet...
How exactly would this work?
A team of vets going house to house killing dogs?
Where will they come from, vets go into veterinary medicine to save animals not kill them. They are independent businesses/employees, not government staff so, who is going to make them? Who will pay for this if they could be found? What would be in place to protect the MH of those vets?
How will you find them all, this would lead to many owners hiding dogs (which is a big part of the problem already, hidden dogs do not have their needs met, are untrained, unsocialised, suffering and far more likely to be dangerous should they escape or be exposed to situations they've no ability to cope with).
Do you suggest every home in the UK is searched for XL bullies?
Forcibly taking and killing peoples dogs in front of them is likely to be highly stressful for everyone and very high risk for all involved. Again, why should vets (who, unlike police officers, did not sign up for the risk of being punched/stabbed etc in the course of their everyday work) do this. What law is there in place that could be used to force them to do this?
Or do you mean for police to seize dogs and transport them to some killing facility - where is this facility (or facilities) please?
Killing dogs takes time and the legal methods require fairly close handling, or are you proposing to change our laws on euthanasia methods so that dogs can be gassed in large numbers as is done in some US states and parts of Japan?
Otherwise who is funding the seizure, transport, and housing of huge numbers of dogs, all of whom are liable to kill a person at the drop of a hat lets not forget, whilst they wait to be killed?
It was easy to add XL bullies to the existing breed specific laws, as all the work for that was done when pitbulls were banned.
I do not believe there is anything in place already that would allow any authority to destroy property simply because it exists (as opposed to where a crime was wilfully and with intent, committed), particularly property owners have just paid to meet the various conditions and exempt their property. I assume those people would be refunded and they'd have a good compensation case too for their expenses - who will pay for this?
Given the governments figures for how many XL bullies there are in the UK were WAY off... (they estimated around 10 thousand. It is more likely closer to 100'000) do you think this is a proportional response to less than 1% of the xl bully population being killers?
