Comparison of the effectiveness of a purported anti-static cape (the Storm Defender®) vs. a placebo cape in the treatment of canine thunderstorm phobia as assessed by owners’ reports

Abstract: Canine thunderstorm phobia is considered a noise phobia, however, it has been theorized that pain associated with discharge of accrued static electricity could contribute to this malady. This project aimed to determine if a purported anti-static cape (the Storm Defender®) and a non-anti-static cape (placebo cape) were therapeutic for canine thunderstorm phobia. Twenty-three owners used either the Storm Defender® (n =13) or the placebo cape (n =10) on their dogs during four thunderstorms. A baseline pretreatment anxiety score (pre-cape use) and four treatment anxiety scores (with use of a cape) were generated by scoring owners’ responses to 12 questions that concerned the severity of behaviors associated with thunderstorm phobia. Use of both cape types was associated with a statistically significant decrease in median anxiety scores from baseline. After a fourth cape use, the median anxiety score of the Storm Defender® group decreased by 63% from baseline (P =0.005) and the placebo cape group''s median anxiety score decreased by 36% (P =0.002). Owners in both groups indicated that their dogs displayed significantly less hiding behavior by the fourth use of the cape. Seventy percent of owners who used the Storm Defender® on their dogs and 67% of the placebo cape owners reported some degree of improvement via a global assessment score, made after the fourth use of the cape. There was no statistically significant difference between the Storm Defender® and placebo cape groups in their baseline pretreatment anxiety scores, median treatment anxiety scores or in their owner global assessment. The results indicate that use of a form-fitting cape may be moderately therapeutic in treating canine thunderstorm phobia. More research is needed to determine why owners reported effectiveness with both cape types. [Copyright &y& Elsevier]
