This is Charlie, he is a terrier Chihuahua mix. He is 3 years old and in May we learned he had diabetes. I got the collar wondering if I could correlate any of his behaviors to some sort of indicator. I have been amazed at the outcome. Every night he will start to whine in his sleep and then wake up within minutes. Each time it has happened, and it happens several times a day, the Petpace collar has sent me a Low HRV (Heart Rate Variability) warning indicating he is under some sort of stress or chronic pain. I get up each time and walk him, he is usually VERY thirsty (due to the diabetes) and then give him a treat and put him back to bed.
In addition, something I did not think about but absolutely love, is tracking his activity during the day. I know from his patterns now when my husband has taken him out, when he has been walked, when he has eaten etc. All from my desk at work!!! I Love being able to know what is going on at home while I am remotely located.
