Is that a question for me? No deaths are acceptable, either of people or dogs through maltreatment. As I've said elsewhere, I would advocate compulsory licences for dogs owners, compulsory training for owners to include canine communication and body language and care of dogs, regulation for all aspects of canine care industry, including breeders, trainers, dog walkers, etc.
However, I still maintain it's important to avoid scaremongering hysteria. If your figure of 20 hospitalisations per day (actual hospitalisations or people needing treatment?) is correct, that's still one case for every 650,000 dogs.
Would you also advocate banning cars, drills, ladders, etc?
