It is euthanasia due to unwanted behaviours!
What a terrible statistic!

The answer is to recognise the problem quickly and work towards a solution.
Most problem behaviours start small and grow over time.
The faster we act, before things are too well practised, the better the chance of success is.
It is also important to note that there are very few shortcuts or quick fixes.

Sometimes, the problem behaviour is a symptom of a bigger picture.
For example, boredom is a huge issue for many dogs. It can lead to:
*nuisance barking
*destructive chewing
*digging
*escapist tendencies
*self mutilation
