Evaluation of dangerous dogs

Evening seminar

More and more countries have laws that restrict owership of certain dog breeds because they are thought to be dangerous. The police are also given increased rights to remove dogs, evaluate them and decide to have them euthanized. But who has the necessary background or knowledge to evaluate a dog’s “dangerousness”?

Are there specific tests that show if a dog is a risk to people and animals?  What does statistics say regarding the number of people seeking medical help after dog bites? Who are bitten? Does the dog owner play any part in a dog’s “dangerousness”? We are discussing those and many more questions in this evening seminar.

Dogs are not dangerous. They have strong intuitive bite inhibitions and warn several times before they feel force take to violence. A few dogs, however, have been so aggressive that they were deemed dangerous. (Compare with human beings.)

It is important to make a correct diagnosis. A dog is not dangerous to people or other dogs because the owner is failing in his/her leadership – which is the most common diagnosis or explanation today. Neither is the dog dangerous as a result of being “mentally bad” – a diagnosis of the day a few years ago. Mental tests do not say anything about about one specific dog and is therefore nothing you can use on angry dogs. We go through the reasons very carefully.

The reason for a a dog being aggressiv is above all pain, disease, hormonal disfunctions, life in a socially bad environment as well as bad experiences.  All of this is possible to research – and that is exactly what modern dog psychologists do!

In this evening seminar we go through how to evaluate the degree of a dog’s aggressiveness and how different views will lead to a different diagnosis of the same dog – from a hopefull case to a hopeless.

Furthermore, we discuss concepts such as dominans, common causes of aggression and that aggression is not just one thing, but can be divided into many.

Att vara Hundpsykolog och påstå att hundar inte är farliga, att välja att kalla detta för bithämningar då undrar jag hur man egentligen tänker/känner. Det är Extremt farligt när en hund går till attack och i vissa fall går in för att ha ihjäl, hur kan det inte vara det.

    Hundar är inte farliga, en del kan visserligen bli det, även om det är sällsynt. Hundar har starka hämningar mot att använda de enorma krafterna i sina käkar. Det är många stadier som en hund går igenom när den blir arg, från en mängd varningar med morrande, mimik och kroppssignaler och till markeringar av bett i luften, nafsande och riktiga bett av olika styrka.

    Det verkar som om du uppdatera dina kunskaper om hundens etologi. Jag vill därför rekommendera dig att läsa på. Det finns modern litteratur i ämnet. Du kan t ex läsa boken ”Etik och Etologi – För ett lyckligt hundliv”, som har många vetenskapliga referenser till grund.
