Abstract

This study was divided into two experiments. For the first experiment, heart rates during exercise of 21healthy male dogs were recorded. The animals were brought to swim every 2 days, 8 times in all, for 10 minutes.Heart rates were measured every minute using a pulse watch. For the second experiment, 134 healthy adult dogswere categorized into three groups: small (41), medium (51) and large breed (42). Their heart rates were measuredevery minute for 34 minutes after the 5th swimming. In the first experiment, the heart rates during the 1st–4thswimming were significantly higher (p<0.05) than during the 5th 8th swimming. In the second experiment, the heartrates were significantly different (p<0.05) between small, medium and large dogs. No correlations were foundbetween weight, age, and heart rate. From the results of the second experiment, we were able to formulate anequation for predictable heart rate of each group of dogs (small, medium and large dogs). From the results, werecommend that the limits on the length of time spent for aquatic exercise should be 15–30 minutes, depending on thebreed (size) of dog. Moreover, there should be trainers observing each dog to prevent over-exercise.
