I am a dog owner. My dog plays with my children. I wouldn't let them play together unsupervised but I trust my dog as much as anyone can trust a dog (which is never 100% but can be fairly high). She is the gentlest dog going.
There are three things that are essential to this:
- My children have been trained how to behave around dogs and to recognise the signs that the dog may not want to engage.
- I am always on hand to intervene if I see those signs and the children are ignoring them. I have made it a responsibility of mine to learn about dog behaviour so I can see even the most subtle signs.
- My dog is extremely well trained and treated as a dog at the lower end of the pack - not a substitute human or leader of the pack.
I do not take unnecessary risks. I don't even do it consciously these days as it is second-nature to me, but I am always risk-assessing prior to and during any interaction between dog and child.
I don't know the ins and outs of this case, and I would never seek to judge a woman who has just lost her child in the most awful circumstances. That woman deserves nothing but sympathy right now.
However, as a wider debate on the subject of dogs and responsible ownership, I am frequently horrified by the awful understanding many people have about their dogs. Many don't even have the most basic understanding of canine psychology - which is the most powerful tool you have when it comes to having a dog who can be an asset to your home rather than a liability (at best) or a dangerous accident waiting to happen (at worst).
I don't think dog licensing is the answer unless we employ enough dog wardens/police to make it a probability that you will be stopped and asked to produce your licence. Otherwise all that will happen is that the good owners will pay for the licence and the bad owners will simply ignore it.
If we did have a licence, however, I would make it a condition of that licence that all dog owners either have to attend training courses, or pass an exam about dog behaviour and training.
