Scared and fearful Mastiff

What Causes Fear In Mastiffs?

Mastiffs are very courageous dogs, so it’s a cause of worry to see your once brave pet become scared. Unfortunately, there are no easy answers to helping your mastiff recover from this fear. However, you can adopt several steps to enable it to gain courage again. 

Factors that cause fear in mastiffs include inadequate socialization, pain, traumatic experiences, and genetic predisposition. Luckily, proper training can aid in socialization, and a vet visit should help with any discomfort. However, it becomes more complicated when looking at trauma and genetics.

Fearful behavior is strange and unpleasant to dog owners, and the last thing you want to see is your sweet companion being startled by every little trigger. However, it is quite common in dogs of all breeds to show signs of fear. Still, dogs do not develop these tendencies without reason. 

Let’s go over some of the most popular reasons why a mastiff may suddenly become scared.

Inadequate Socialization

Most dog experts suggest that a lack of proper socialization can cause a dog to develop anxiety disorders. This is why vets often advise positive exposure to other animals, people, and environmental factors during their critical fear period (more on this later). 

From a young age, dogs need to experience a variety of pleasant interactions to help them get used to the unexpected. Mastiffs may grow to become wary of new or unusual things if they are not properly introduced to the world from their puppyhood stage.

Pain

Just like humans, dogs react to pain in different ways. Some dogs may act scared and shake when exposed to certain levels of pain, where others may lay still for hours on end.

Mastiffs usually act out and are visibly shaken if they feel pain in their neck, back, or abdomen, which may also limit them from walking. It’s not uncommon to see dogs lash out when touched for fear of experiencing more pain. 

So, next time you notice your mastiff visibly terrified, it could be that they’re actually trying to alert you to an injury. 


Pro-tip: Does your Mastiff have issues with anxiety, destructive chewing, aggressiveness, jumping up, barking or fearfulness?

addresses these behavioral issues as well as dog training basics.

Traumatic Experiences

Another theory is that your furry friend may have had some traumatic experiences in the past. For some dogs, it takes a single traumatic event for them to develop lifelong fear responses.

For instance, your mastiff may develop a fear of loud noise because of an incident with firecrackers on the Fourth of July. In this kind of situation, you may see their fear triggered at the sound of anything from a car door slamming to thunder.

Genetic Predisposition

Some dogs may also become nervous because of their genetic predisposition. This could be why your mastiff will sometimes pick up the habit of shyness or fearfulness from a young age. 

In addition, puppies are very likely to become fearful if they are born to nervous mothers.

Mastiff Fear Stages

One critical aspect to consider when learning about your mastiff's fear is its different stages. Fear stages are expected for every dog, especially during their puppyhood days. This period leaves puppies more sensitive and aware of the world around them. 

Unfortunately, no amount of socialization can stop your mastiff from passing through this period. However, there are some ways in which you can help make this phase a little easier. 

Here's a brief overview of the different stages of fear.

Fear Imprint Stage (8-10 Weeks)

If you understand a dog's development, you'll know that this is a crucial period in their development. It is the stage where puppies develop social skills and understand the world around them. 

Subjecting your mastiff to physical or psychological trauma during this time can make them susceptible to developing a lifelong avoidance response. This is why it’s not recommended to take puppies from their mothers at such a young age.

Adolescent Fear Period (12 Weeks - 6 Months)

At this stage, puppies have become autonomous, but they're learning about the world. 

Painful experiences like teething can cause them to become scared, and you may begin to see noticeable changes in your puppy as early as 12 weeks. 

The best way to help your puppy through teething is to provide them with plenty of chew toys (nothing too hard) and to never yell or punish your puppy for chewing up something they shouldn’t.
 

Flight Instinct Fear Period (6-9 Months)

This is a very critical stage in every dog's life. Unfortunately, mastiffs generally find this period challenging, and that's why you may suddenly find them scared of strangers or other dogs. 

Experts often refer to this phase as "teenage flakiness." You may notice your dog becoming afraid at the silliest of things. 

During this stage, it is often recommended to not overexpose them to new people or places.

Adult Fear Period (12-18 Months)

Dogs generally continue to experience the fear period even after the one-year mark. But, again, this is because they are still growing; most people relate this fear period to the surge in growth and development that occurs at this point.

The key thing to remember is that all of this is normal and that your puppy should outgrow the behavior.

Helping Your Mastiff Overcome Its Fear

Unfortunately, helping your mastiff overcome its fear is not as easy as you think, and you may need some level of trial and error to determine the best for your dog. 

But, if you are ready for it, here are three tips that can help.

Don’t Encourage Their Fear

People often encourage their dog's fears without knowing it, as it's natural to want to comfort your mastiff when you notice that it's in distress. Unfortunately, some dogs see this as a reward for their fearful behavior. This can “teach” them to continue behaving in a certain way to get attention and treats. 

Instead of comforting your mastiff, we recommend remaining as calm as possible and not giving treats without them earning it. It is better to try and distract your mastiff and give treats when they perform and trick instead.

Expose Your Mastiff to Their Fear in a Controlled Environment

Your pet's fear may be a result of certain noise or other familiar stimuli. If this is the case, you can help it overcome the fear by desensitizing it. 

One of the best ways to do this is by exposing it to the stimulus in a controlled setting. 

For example, if your mastiff is afraid of loud noises, such as thunder, try playing thunder sounds on your phone quietly. Turn the volume up gradually, and always keep an eye on how your dog is reacting. 

Over time, your mastiff should become more used to the sound, and you should be able to turn the volume right up without them reacting at all. 

Note: Experts warn that you work with a vet or a trained expert when attempting this kind of desensitization. Doing it without professional guidance may make matters worse. 

Visit a Vet

Nothing beats having an expert look at your dog's situation. Make notes of your mastiff’s reactions, and try to get a video if possible to show your vet how they respond to certain stimuli. 

Your vet will be able to decide whether your dog needs physical therapy or medication to overcome its fears. They may even have a few simple tricks to try at home.

If you have a pet sitter, ensure to communicate your dog's specific needs to them.

Final Thoughts

Dogs can exhibit many different habits, but fear is one of the oldest and most common. Before taking any action, it's essential to carefully monitor your mastiff to know what may be wrong. Remember, you could be seeing a sign of pain rather than a fear response. 

If your mastiff is still a puppy, chances are it is going through the normal fear stages all dogs experience. However, if your dog is an adult and suddenly developing fearful responses, you may need to visit your vet for a check-up.
