Canine Astraphobia in an Eleven-Year-Old Border Collie

Written by Sarah Penrose

Homeopath Sarah Penrose shares a case of astraphobia in an eleven-year-old border collie. fear thunderstorm, attempts to escape, desires company and sudden fear were among the rubrics leading to the simillimum.

Canine astraphobia, noise sensitivity, homeopathic therapy, case report.

Anxieties and behavioural problems in dogs can decrease their quality of life (Salonen et al., 2020), rendering them more vulnerable to disease and shortening their lifespan (Dreschel, 2010).

Behaviour has a major genetic component (Ilska et al., 2017). Behavioural traits are complex and affected by intricate interactions between genes and environmental factors (Overall et al., 2014), with some genomic areas and loci associated with fear and noise sensitivity (Sarviaho et a., 2019).

Noise sensitivity is the most common anxiety-related trait in dogs (Salonen et al., 2020), with an estimated prevalence of between 20% and 50% (Tiira et al., 2016).

Typically noise sensitivity is generalised and displayed toward several different noises (Blackwell et al., 2013). Fear of fireworks is the most common sub trait with a prevalence of 26%, followed by fear of thunder at 16% (Salonen et al., 2020).

Case report
Matilda, an 11-year- old border collie.

Initial consultation
01 December 2021.

Main complaint
Canine astraphobia.

Matilda has had three litters, and lives happily with her owner and two other border collies, one of which is her five-year-old daughter who she continues to mother.

From eight weeks of age Matilda becomes frenzied from loud noises including fireworks, hard rain on the roof, and vehicle backfire, but particularly during thunderstorms when she attempts to break out of the house any way possible, scratching at doors, destroying window coverings, damaging the house and herself in the process.

At age eight Matilda escaped from an impossibly closed metal dog crate where she was placed in anticipation of an oncoming thunderstorm when her owner had to leave for work, destroying three-day old cruciate ligament surgical repair, ruining her mouth, leaving so much blood the house resembled a murder scene, and digging out under the fence only to become trapped in the neighbour’s swimming pool gate, and subsequently rescued.

Matilda’s owner has ‘tried everything’ to help her including a thunder jacket, playing thunder audio to desensitize her ‘but she’d freak out’, Valium – which her vet guaranteed to work – ‘turned her crazy’ making her owner want to take it herself! A proprietary zeolite liquid helped to calm her down, but this is expensive and has run out, and not been administered for a few months.

Salonen et al., (2020) found one quarter of the border collies in their study showed fear of thunder, which they also suggest becomes prevalent, at 35%, in females of all breeds aged over ten years.

Matilda knows a thunderstorm is coming well before the clouds gather, becoming increasingly terrified, panting, shaking, and ultimately trying to dig her way through the carpet, the bed, the floor, the couch, attempting to escape through anything including windows, and to smash her way out of the doors.

It is impossible to calm her down, talking to her, holding and loving her, and lying with her has no effect at all as Matilda tries to dig through her owner, and will run right past her to get out the door.

This is ‘horrendously sad’ for the whole family, but particularly Matilda who historically if she succeeded in escaping would always run to the same friend’s house, even though she has love and safety and company in her own home. When they moved, her owner was constantly terrified she’d escape and run and run, and never be found – sadly a common occurrence in the outback.

Stramonium 10M – one dose to begin.

Stramonium has tremendously intense and energetic pathology, with states of mania and violence presenting as extreme fear, where the individual is uncontrolled, impulsive, and possessing super human strength, but often without aggression (Morrison, 1993).

Shortly after administration of the first dose, in the face of a thunderstorm Matilda knew was coming well before it arrived – even before any clouds had formed, she displayed her usual terror but was panting and shaking in a way her owner hadn’t seen before ‘like she’d run 10kms.’ After a while, even as the storm intensified, her terror, panting, and shaking subsided drastically, and although still present Matilda stayed right by her owner’s side for the first time in her life without a frenzied desire to escape.

Intensification of symptoms for a few hours followed by rapid amelioration is an excellent reaction, indicating a good state of overall health, and proving the remedy is correct through its ability to elicit that strong initial response (Vithoulkas, 2017).

Date Occurrence Dose
(at owners’ discretion)
20.12.2021 Heard thunder, began to pant and shake. Stramonium 10M Symptoms subsided to 1% of typical.
03.01.2022 Wide eyed at incoming thunderstorm. Stramonium 10M Calmed, lay beside owner no panting, shaking.
28.01.2022 Looked out the window as a thunderstorm began. Stramonium 10M Lay beside owner and was calm.
18.02.2022 Midnight thunderstorm, jumped up on to owner’s bed. Stramonium 10M Back to sleep in 10 minutes beside the bed.
03.03.2022 Thunderstorm as owner was leaving for work. Stramonium 10M Calm when owner returned, no damage to Matilda or the house.
28.04.2022 Heavy rain, began to pant. No dose required. Ventured outside and lay on veranda, calm.

According to allopathic veterinary practice, canine astraphobia can only be mitigated. Behaviour modification, desensitization, medications, or a combination of these treatments, coupled with preparation, perseverance, and patience are encouraged to ‘help dogs to feel safe instead of scared’ (Strommen, 2022).

The use of and interest in veterinary complementary medicine is increasing internationally, with a 2022 survey finding 85.4% of German veterinarian respondents implement complementary medicine in their practice, homeopathy being the most utilized, with 44.3% practicing classical homeopathy (Stanossek and Wehrend, 2022).

Homeopathy, a hotly debated but often used personalized therapeutic medical intervention, has been shown to alleviate stress responses in pigs (Dang and Kim, 2021). Frequently used by human anxiety sufferers (Pilkington et al., 2006) homeopathy shows possible benefit in psychiatric complaints (Davidson et al., 2011) such as anxiety disorders (Hock and Juckel, 2018; Parewa et al., 2021), and as a side note, meta-analysis identified greater efficacy for homeopathy over fluoxetine in major depressive disorder (Rotella et al., 2020).

Thunderstorms were a lifelong trauma for Matilda and her owner who ‘got no sleep on stormy nights with a freaking out dog digging through anything,’ and who sometimes slept in the car, the only place of calm, after driving Matilda around and around.

Homeopathy can improve quality of life (Frass et al., 2020, Witt et al., 2008, Bell et al., 2004) which in Matilda’s case has had significant flow on effects to her owner. Small animal veterinary studies are required to assess the efficacy of homeopathy in canine astraphobia.
