Behavioral changes

Dogs are loyal companions who bring us a lot of joy. But sometimes they behave differently than usual. They are anxious, aggressive, restless or apathetic. What is behind this? And how can you help your dog?

Possible causes of behavioral changes

Behavioral changes in dogs can have various causes. Some of these are

  • Physical illnesses: Pain, hormonal imbalances, infections or other illnesses can affect your dog's behavior. If your dog is suddenly lethargic, irritable or lacking in appetite, you should consult a vet.
  • Psychological problems: Stress, anxiety, trauma or boredom can also lead to behavioral changes. For example, a dog that has too little exercise or activity may start barking, destroying or marking. Or a dog that has had a bad experience may react fearfully or aggressively.
  • Changes in the environment: Moving house, new family members, visitors or other animals can make your dog insecure or jealous. He then needs time and support to adapt to the new situation.
  • Ageing: Your dog's behavior also changes with age. He becomes calmer, sleeps more and learns more slowly. His hearing, vision and sense of smell may also deteriorate. This can confuse or frustrate him.

Tips for dealing with behavioral changes

If you notice a change in your dog's behavior, you should first find out the cause. To do this, it is important that you observe your pet closely and understand its body language. A visit to the vet can also help to rule out or treat possible physical problems.

Depending on the cause, you can then take various measures to help your dog:

  • Offer him safety and security: give your dog lots of love and attention. Praise him for good behavior and ignore unwanted behavior. Don't scold him or punish him physically. This would only frighten or upset him even more.
  • Providesufficient exercise and activity: A busy dog is a happy dog. Take him for regular walks, play with him and challenge him mentally. For example, you can teach him tricks or play search games.
  • Create a retreat for him: Sometimes your dog also needs peace and privacy. Provide him with a cozy place to sleep where he can relax. Respect his needs and leave him alone when he retreats.
  • Get professional help: If your dog's change in behavior is very severe or lasts for a long time, you should consult an animal psychologist or a dog trainer. They can give you individual tips and show you how to train your dog.

Behavioral changes in dogs are not always a cause for concern. They are often only temporary or easily remedied. It is important that you show your dog that you are there for him and that you are helping him to feel comfortable.
