Dogs communicate their feelings and needs through behaviour. However, sometimes dogs may show unusual or abnormal behaviours that confuse or worry their owners. When a dog shows actions that seem unusual, disruptive, or distressing, it’s often labelled as *abnormal behaviour. These behaviours can include excessive barking, aggression, destructive chewing, anxiety, or obsessive habits.
This guide explains the common abnormal behaviors in dogs and how to correct them effectively, helping owners raise well-behaved and happy pets.
Abnormal behaviour refers to actions that are excessive, repetitive, harmful, or out of context for a dog’s age, breed, and environment. Examples include sudden aggression, constant barking, destructive chewing, self-injury, extreme fear, or withdrawal. While every dog has a unique personality, behaviours that cause distress, damage property, or threaten safety are considered abnormal.
It is necessary to stop these bad habits before established. Later on, when habits become a nuisance, it becomes very difficult to change these habits. Identifying these behaviours early helps owners take corrective steps before the problem worsens.
Pet owners should consider the following factors to establish the cause of the abnormality.
Dogs that are not exposed to people or other animals early in life may become fearful or aggressive towards strangers, children or other animals
.2. Lack of Exercise
Dogs with too much pent-up energy may develop destructive habits
Traumatic experience causing a conditioned emotional reaction is frequently seen in the normally reared dog. For example, a second visit to the veterinary clinics may result in hyperthermia, fright, fight and fear reactions. Changes in the environment, loud noises, or loneliness can trigger abnormal behaviour.
Pain, illness, or neurological issues may lead to sudden behavioural changes.
Dogs that do not receive proper guidance may develop unwanted habits.
.
Extreme aggression may arise due to traumatic experiences during the critical period of socialisation or social isolation during this period. When the
A pup is taken as a pet and lives a fairly isolated life in an apartment (in cities),
Socialisation with other dogs and people is greatly reduced, resulting in extreme aggression towards strangers or other dogs.
Solution- Gentle handling and re-socialisation will be helpful a lot in such a situation. In extreme cases, sedative drugs may be given in consultation with a veterinarian.
When the dog becomes a child substitute of the family and overprotects it, it becomes dominant and overprotective towards the owner and aggressive towards strangers.
Solution- The dog should not be over-patted, and any undesirable activities must be stopped by a sharp command like.No. Follow the basic rule of training- Undesirable activities must be followed by a sharp NO, and when the dog obeys your instruction, reward it.
Chewing is normal for puppies, but when dogs destroy furniture, shoes, slippers, etc., it should be stopped at the start; they will soon become established and difficult to correct, and then your dog may destroy your valuable household items. It may indicate boredom or anxiety. This is particularly seen in puppies when tooth eruption starts, and adult dogs usually chew inanimate objects out of separation anxiety.
Solution-
Allow puppies to have things like (non-splintering long bones, synthetic bone, rubber-dolls,rubber-balls, etc.) which they can chew on and can identify as their own. If you allow a bone, ensure that it is a suitable one. Act very promptly when the wrong things are being chewed, such as furniture, doormats, slippers, shoes, etc.
Barking in dogs is a natural activity, for it serves as a means of communication, particularly of expressing warning and serves to express pleasure. Barking
serves to tell you when you have visitors, but it should stop as soon as they are identified as friends.
Excessive barking may be due to poor training, leaving the dog alone for a long period frequently, lack of proper exercise, failed to relieve natural calls.
Solutions- Controlling barking in old dogs is difficult because old dogs cannot alter their habit of barking, but it is necessary to do something about the excessive noise from your dog. To avoid the situation, providing adequate training and opportunities to get bored should be kept as few as possible.
You can suddenly start a louder noise when the dog starts his unwanted barking, and in this way, you can make an effort to control the barking in adult dogs.
When you take your dog on a lead near public roads for exercise, many dogs start chasing nearby passing scooters/motorcycles and bicycles, which is not only irritating but also dangerous and may lead to a serious accident.
Solution
Never allow your dog to chase. Motor vehicles and the practice of chasing must be stopped soon after it develops. Try to exercise your dog in an area away from public roads or roads with minimal traffic. If it is difficult to keep a dog away from traffic, then a lesson to stop this habit is necessary. Allow your dog to chase a car in a safe place, but instead of appearing to be chased away, stop the car and lay down empty cans from the car. In extreme cases, you may have to repeat the lesson several times.
Many dogs jump up on their owner whenever they enter the house, especially after a long gap, returning from a trip. from office etc.afterGenerally jumping up is a delightful expression of devotion by dogs, and is less appealing if you get muddy paws on your clothes or those of others. This habit should never be allowed to start.
Solution
Always give a strong NO command every time your dog tries to jump up on you or anybody. Gradually your dog will understand that it is a bad manner and may refrain from such activities. You can also overbalance your dog with a well-placed nudge with the knee, and it may take some time to stop this habit.
When family members are taking food to the dining table, dogs frequently beg at the table, which is an undesirable habit. Such a dog always expects food when other family members are eating. The dog which develops this habit gives the impression that he never gets any food, by seeing his anxious look towards the table when you and your friends are taking a meal.
Solution
Dogs habitually pull when they are on the lead. Many large-breed dogs get very excited when they know they will shortly be taken for a walk.
Solution
If possible, give a quick run in the lawn, off the lead, which helps to overcome the excitement
Some dogs cannot resist stealing food if left alone where lots of tempting food is visible. Such a habit should be treated as unacceptable. Dogs also develop a habit of taking food from strangers once they are given free access to take food wherever they like, no matter from which he is getting food.
