What is Causing My Dog's Anxiety?


Do you have a dog whose tail is almost always tucked between their legs and they can’t seem to settle?

Or maybe they always avoid eye contact when you try to look at them and they retreat to the other room or into a hiding place often? If so, your dog likely has an anxiety disorder

Besides the tucked tail, fidgeting, avoidance of eye contact, and hiding behavior, anxiety signs and symptoms also include:
  • Spontaneous elimination (urination/bowel movement)
  • Destructive behavior
  • Panting
  • Pacing
  • Whining/whimpering
  • Passive escape
  • Trembling
  • Excessive licking
  • Dilated pupils
  • Avoiding interactions
  • Displacement behaviors: yawning, lip licking, air sniffing, “shaking it off” like a wet dog
A dog may exhibit one or more of these behaviors periodically. It’s normal when they are in an uncomfortable situation. However, it becomes a problem when your dog exhibits many of these symptoms at the same time, any one of these symptoms to the extreme, or is in a constant state of anxiety.

What Causes an Anxious Dog?
Dogs can become nervous or anxious for many reasons. Sometimes it’s obvious what is causing your dog’s reaction, but sometimes it’s not. In that case, you can often detect what is triggering their abnormal behavior through trial and error or by paying keen attention to when their body language is indicating that they are nervous. 
Dogs can become anxious for different reasons. Three specific types of anxiety are separation anxiety, former rescue (or shelter) dog anxiety, and illness-induced anxiety. A dog can also have general anxiety.

More and more pets are experiencing Separation Anxiety as their parents return to working in the office after working from home for so long. A dog with separation anxiety may become destructive of furniture, bark, whine or howl excessively, or potty in the house when left alone. This behavior can occur whether you’re gone an hour or only 5 minutes.

Separation anxiety is pretty common. Very few dogs actually LIKE being left alone -- they are social animals by nature. Anxiety in this case is most often caused by boredom and loneliness, perhaps associated with a previous negative experience while left alone. It can also be what is known as old-age-onset separation anxiety, which can be caused by a decline in cognitive understanding, or memory, in elderly dogs.
To help a dog with separation anxiety, take them for a walk before you leave, give them a stuffed treat toy to keep them busy, don’t make a big deal about coming and going, or try using one of these natural ways to help a dog with anxiety.

Pets that have spent a period of time in a shelter often have memories of being abandoned and left there. They may also have experienced a traumatic event before they were taken into the shelter or while they were there.
These dogs may just be generally anxious because they dealt with an unpredictable routine or environment. Their general anxiety can also turn into separation anxiety because they fear they are being abandoned again.
Developing a consistent, predictable routine and environment is the best way to help these dogs feel safe at home. A behaviorist or trainer can also help pinpoint their trigger and recommend ways to help them calm down.
Social Anxiety
Dogs that experience social anxiety are more likely to exhibit symptoms like barking, lunging, and aggression when around new people or unfamiliar pets.

Illness-induced Anxiety

Anxiety and fear reactions in dogs can be caused by illness or disease. This type of anxiety usually comes on suddenly in a dog that was not normally anxious.
Some common causes of this type of anxiety are:
  • Hypothyroidism: when fear responses and anxiety symptoms are coupled with weight gain, hair loss or lethargy, the cause might be a thyroid gland that doesn’t produce enough hormones
  • Thyrotoxicosis: also called Grave’s Disease, a rare autoimmune disorder that affects the thyroid gland
  • Encephalitis: inflammation and swelling of brain tissue can lead to anxiety behavior, as well as aggression, seizures, clumsy gait and even coma
  • Pre-diabetes: when new generalized anxiety is accompanied by weight gain, excessive thirst or appearance of cataracts, pre-diabetes may be the issue
  • Hearing or vision loss:  dogs without one of their senses may startle easily and become anxious of their unknown surrounding
If your dog exhibits a sudden or extreme behavior change, take them to the vet so they can rule out any underlying medical conditions. If they are otherwise healthy, they may be anxious for one of the other reasons listed in this article.

Generalized Anxiety

Unfortunately, a cause for anxiety can’t always be determined. It might be that the primary event that caused the onset of anxiety happened in the past and went unnoticed or occured before your pet became a member of your family. It’s also possible that your dog is just prone to anxiety and they get upset anytime there is a change to their routine or environment.
Generalized anxiety is very common and often goes unrecognized. Sometimes that is because the symptoms are subtle and don’t seem abnormal. Sometimes what is actually general anxiety is shrugged off as a common characteristic of a breed when, in fact, is not necessarily a “normal behavior”.
Dog breeds prone to general anxiety include:
  • German & Australian Shepherd
  • Labrador Retriever
  • Vizsla
  • Border Collie
  • Shorthair Pointer
  • Cocker Spaniel
  • Bichon Frise
  • King Charles Spaniel
  • Greyhounds
  • Havanese
  • Many toy breeds

Developing a consistent schedule, controlling social interaction, and creating a predictable environment with low stimuli is the best way to help a dog who is generally anxious.
