Is the addition of spray homeopathic in feed able to change dog behavior?

Abstract

This study aimed to determine if the homeopathic formulation based on Natrum muriaticum, Matricaria, Chamomilla, and Ignatia amara was effective for stress control in dogs in order to prevent and/or reduce the frequency of unwanted behaviors. Ten male beagle dogs were divided into two groups, with five animals per group. The control group was animals receiving 0.5 mL/day of placebo via spray in the feed for 30 consecutive days as a preventive. The treated group received 0.5 mL/day of tested drug spray in the feed for 30 consecutive days as a preventive. Behavioral tests were performed at two time points, before and after receiving the tested drug. We performed the following behavioral tests: a) persons known and unknown in the internal and external environment; b) interaction with toys; c) interaction with an unknown dog, d) test with a leash; and e) firecracker test. There was more engagement in digging and scaling the fence in the control group than in the treatment group (P < 0.05). The animals that received homeopathic medicine sat 2.54 times longer than the control (P = 0.0269). Dogs that received homeopathic showed 4.49 times more interest in general at D30 than at D1 (P = 0.0214). Animals in the treated group showed an 83% less chance of urinating than the control group in the tests involving displacements. We conclude that the preventive addition of homeopathic medicine containing Natrum muriaticum, Chamomilla, and Ignatia amara reduced undesirable behaviors related to anxiety and increased the incidence of interest behavior.
