Pet Trackers & Smart Collars

Could you please recommend an activity tracker for my puppy (one that does not require a monthly subscription)?

Hi, my name is Julia and I am a college student working on a device that will function as a smart collar for dogs. I know the market already has some of these but I was wondering what features do you think are the vital ones that need to be included in this device. We have a GPS tracker, hope to have a heartbeat sensor, and outside temperature thermometer. But what else do you think would be vital to have measured to have a comprehensive image of a dog's health? We would really appreciate it!

I have two neutered cats who love being outside. We live in a mountainous area with wildlife, so we are trying to keep them inside but they learned how to open doors. We are trying to decide b/w a wireless pet fence in our yard where they wear large-ish shock collars (even though they are smaller for cats) all the time as the company says not to wear for more than 12 hours or to just put cat trackers on them and find them every night. Which is safer?

So my puppy chews her fencing of her dog run. A high respected trainer recommended a remote stem collar, as it isn’t SA as she doesn’t care about me when she comes out just wants to sniff and play outside, so what I’m going to do is have someone leave in a car and stay and if she chews the run she gets a stem, the trainer said she trained a few dogs with same issue and fixed within a week -2.
