Terminology
Often referred to as thunderphobia, but for many dogs other storm related stimuli are at least as, if not more important, than the sounds of thunder.
Phobia
Fear reactions that
- are consistent in terms of what causes the fear
- are learned, irrational, not adaptive
- May be, but is not necessarily intense (hysteria, catatonia, panic)
"Normal" Fear vs. Phobia
- Experiencing fear every time a hungry lion charges at you is normal (run, hide, defend)
- Experiencing fear when lightning hits a nearby tree is normal (run, hide)
- Experiencing fear every time there is a dark cloud in the sky is a phobia
Interaction of Stimulus X Fear
- Traumatic/Aversive Events
- Restricted Early Experiences
- Unintentional Reinforcement
Management Steps
- Under NO circumstances should punishment be used
- Relaxation...Keeping the pet calm and relaxed in general is an very important part of treatment
Treatment may be simple:
- Bring the dog indoors during the storm
- Provide television or radio "noise"
- Dog may be ok as long as owner is present
- Provide "safe hiding place"
May be serious and not respond to simple treatment
Composite fear
- change in barometric pressure, ionization, illumination
- Maintenance drug: gets daily
- Fast-acting drug: gets as needed
Behavior modification
Maintenance Drug
- At least for length of storm season
- Relief from chronic, mild to moderate anxiety
- Some anxiolytic effect if owners miss storm-specific dose
Fast-acting Drug
- To get dog through the storm NOW
- Maintenance drug may not be sufficient when severe storm immediately overhead
- Fast-acting anxiolytic effect
- Some notable for anti-panic effects, especially alprazolam
Behavior Modification
- Desensitization and Counter-Conditioning
- Begin with lowest intensity stimulus that the pet exhibits a fear response to
» Sounds
» Sights
» Smells
» Other
Maintenance Drugs
Tricyclic antidepressant
Clomipramine 2-3 mg/kg b.i.d.
Selective Serotonin Reuptake Inhibitor
Fluoxetine 1-2 mg/kg daily
Paroxetine 1-2 mg/kg daily
Fast Acting Drug
Diazepam 0.5-2.0 mg/kgAlprazolam 0.02-0.1 mg/kg
DS&CC
- Expose pet to a very low level of stimulus
- Counter-condition with food when relaxed or playful
- Very gradually increase the intensity of the stimulus until it approximates actual levels
- If at any time the pet experiences anxiety or fear, move back to lower stimulus level
Pheromones?
D.A.P. may be beneficial in some cases.
