Who’s the boss?
Now your dog is becoming an adult, it’s important he knows who is pack leader and that this is continually reinforced. Use our simple techniques, below, to help your dog find his place in the family…
Types of aggression in dogs
• Dominance – often directed against family members and giving rise to the well known phrase ‘biting the hand that feeds you’. Dogs can become very territorial on their home turf and come to see themselves as top dog or pack leader: able to come and go as they please without being challenged.
• Fear – some dogs learn to use aggression as a form of defence, for example, against a stranger, or in a situation that frightens them. Early socialisation with a variety of people will help your dog adapt to new people and new situations without being afraid.
• Jealousy – this is fairly common between a resident dog and a newcomer but giving separate toys, equal attention and avoiding bones should all help. Some dogs also become attached to their main carer and jealously guard them, even from other members of the family.
• Maternal – a bitch will defend her pups if she thinks they are in danger but early socialisation with lots of different people and giving the new mum plenty of peace and quiet should help avoid this.
• Sex related – some bitches can become aggressive when they’re in season (twice a year) and this is related to hormone surges. Unneutered males may also display hormone-related aggression at any time and this is why vets often suggest castration as a possible treatment.
• Male to male – male dogs fight to impose their sexual dominance. If your dog is aggressive towards other dogs, you need professional training advice but, in the meantime, carry a water pistol and give him a squirt if necessary. Also use avoidance techniques so your dog is more interested in you, a treat or a favourite toy when other dogs walk past.
•Predatory – certain breeds are genetically programmed to chase and kill. For example, the Greyhound is a ‘sighthound’ that hunts using its excellent vision or the Jack Russell Terrier that loves to flush out rats and rabbits.
• Territorial – anyone who’s ever watched a seemingly placid dog turn into a snarling beast while in a car will have no doubt about a dog’s ability to defend its turf and the smaller the space, the more confident the dog may feel.
• Object related – guarding objects, especially food, bones and favourite toys, is a common problem in the home which can eventually lead to the dog being put down if the situation becomes unmanageable. In any case, children should be taught not to put their hands or faces near a dog that’s prone to this sort of behaviour, especially when they’re eating, often the worst situation for this sort of aggression.
Ways to sort aggression
• Get your dog used to being handled routinely by all the members of your family, not just you or her main carer. Groom her daily, if only for a few minutes, to get her used to being handled and touched all over her body, paying particular attention to her paws, ears and mouth. Turn her round so she gets used to being repositioned and moved – this will come in handy at the vets.
• Help your dog to understand his ‘lower than humans’ ranking by using subtle signs:
– you eat first, then feed the dog afterwards
– stop your dog going through doors, gates or up the stairs (if allowed) first
– ignore attention-seeking behaviour, such as jumping up, if talking to another member of the family or a visitor.
– ask your dog to sit nicely before putting down her food.
• Use your posture, facial expressions and voice to speak powerfully (but not shout) to your dog when she’s done something wrong and this will help her understand that you are the pack leader. Dogs are excellent interpreters of body language in humans as well as their own species.
• Try using ‘aversion therapy’ to stamp out any developing aggressive tendencies. For example, use a water pistol to stop her chasing visitors, cyclists or joggers, being aggressive towards other dogs or defending a particular territory, toy or food.
• Exchange food treats for an item that’s being guarded and if she seems to become persistently possessive about a particular object, take it away permanently.
• If you have a male dog that is prone to be aggressive with other male dogs, consider getting him castrated as this will help reduce his bolshy tendencies as well as reduce his desire to wander.Â
A word from the vet
Don’t take any chances with a dog that bites – seek professional help straightaway.
Glossary
Neutering – a routine operation to stop a dog being able to make a female pregnant or to stop a bitch from ever conceiving puppies. Male dogs are castrated, that is, they have their testes removed while a bitch will have the uterus and ovaries removed.
