Why is my dog hiding after taking anxiety medication? Some dogs may hide after anxiety medication because of sedation, emotional blunting, confusion, dysphoria, fear, overstimulation, medication adjustment, or neurological side effects. Mild tiredness and seeking quiet places may sometimes be normal during adjustment periods. However, severe weakness, collapse, seizures, breathing problems, or sudden neurological symptoms require immediate veterinary attention.
Many dog owners become worried when their dog suddenly:
- hides under the bed after trazodone
- avoids family after fluoxetine
- acts withdrawn after anxiety medication
- hides in closets or corners
- seems emotionally distant
- refuses interaction after medication
- becomes unusually quiet
- avoids eye contact or physical contact
And honestly?
This is one of the MOST emotionally upsetting medication reactions owners can experience.
Because owners immediately fear:
“Did the medication hurt my dog?”
Sometimes:
- the dog may simply feel sleepy
- the brain may still be adjusting
- anxiety may still be present underneath
But in other cases:
- dysphoria
- paradoxical reactions
- neurological discomfort
- excessive sedation
- serotonin-related complications
may contribute to more serious concerns.

- emotional instability
Instead of calming:
the dog becomes MORE fearful
This may occasionally happen with:
- trazodone
- alprazolam
- fluoxetine
- multiple medications combined
Possible Signs of Increased Fear
| Symptom | Severity |
|---|---|
| Hiding | Mild to moderate |
