Many athletes wear a collar containing aquatitan when playing a game, and this type of collar is said to have various good effects. Recent experiments showed the effects of aquatitan on animals. However, there are no reports of the effects on dogs wearing an aquatitan-containing collar. In the present study, the changes in behavior of two dogs with an aquatitan-containing collar were examined before and after the attachment. The dogs became more active when wearing the collar. Moreover, five beagles with a collar containing aquatitan and five control beagles were given a three-hour stress test of transportation by car. As stress markers, the number of white blood cells, number of lymphocytes, serum cortisol levels, and saliva chromogranin A levels were examined. All items showed stress patterns, and there was no difference between the two groups of dogs. However, while all the dogs suffered stress, the relative value of serum cortisol was significantly lower in the collar-wearing dog than in the control group. These results suggest the possibility of a cortisol suppressant effect of an aquatitan-containing collar on dogs.
