Cracknell NR, Mills DS. A double-blind placebo-controlled study into the efficacy of a homeopathic remedy for fear of firework noises in the dog

ABSTRACT:

Seventy-five dogs that showed a fear response to fireworks participated in a double-blinded, placebo-controlled clinical trial to assess the efficacy of a homeopathic remedy for the alleviation of their behavioural signs. Dogs were randomly assigned to one of two treatments; the homeopathic treatment or the placebo treatment. At the baseline assessments the owners identified the behavioural signs of fear that their dogs normally displayed in response to fireworks, rated their frequency and intensity, and assessed the global severity of their dog's responses. These measures were repeated at the final assessment and owners also completed weekly diaries for the length of the trial. There were significant improvements in the owners' rating of 14/15 behavioural signs of fear in the placebo treatment group and all 15 behavioural signs in the homeopathic treatment group. Both treatment groups also showed significant improvement in the owners' rating of the global severity of their dog's responses. However, there was no significant difference in the response seen between the two treatment groups.

 

Cracknell N.R. Mills D.S. (2011) An evaluation of owner expectation on apparent treatment effect in a blinded comparison of 2 homeopathic remedies for firework noise sensitivity in dogs. Journal of Veterinary Behavior

ABSTRACT:

A blinded and randomized study was carried out to investigate whether dog owners would report different treatment effects depending on whether they knew they might be administering a placebo, versus if they knew they were definitely administering a homeopathic remedy. A secondary aim was to determine the consistency of owner reports of treatment effect across multiple trial periods. A total of 73 dogs with a stable, predictable, and easily assessable response to firework noises were enrolled and randomly allocated to receive 1 of the 2 homeopathic preparations along with a basic behavior modification program. Treatment A was a homeopathic treatment formulated for firework noise sensitivity that had previously been tested in a placebo-controlled study by the authors, and Treatment B was a different formulation for the same condition. The same allocated treatment was trialed on 2 occasions by all participants to allow assessment of owner-report reliability. It was found that knowledge of participating in a placebo-controlled trial had no effect on the owners’ perception of treatment effect, and that their reports of effect were consistent across both trial periods. No specific effect of homeopathic treatment was found in this study; however, it was observed that the reported behavioral effects that followed each treatment were similar across the 2 firework periods, but that there was a consistently different pattern of behavioral effects reported between Treatment groups A and B. These results might be ascribed to either a treatment or population effect. We suggest that examination of the consistency of owner-reported effects within and between treatments may be used as part of the suite of methodologies available to investigate whether any specific effect can be ascribed to homeopathic interventions.

Use of homeopathy in parasites control plans in a flock of Zerasca sheep

ABSTRACT:

The control of gastrointestinal parasites in livestock relies almost exclusively on multiple and regular dosing with anthelmintics. That involves in problems linked with residues in food products and environment encouraging researchers in studying alternatives or new helminth control methods (Ketzis et al., 2006). Among these, homeopathy could play a strategic role in solving health problems; however, at present, there is a lack of scientific results with validated techniques used on a large scale
