As a doting Chihuahua parent, your dog’s health is a top priority. You make sure your Chihuahua eats the best foods, gets regular veterinary care, enjoys plenty of playtime, and takes regular walks.

Gauging just how much activity your Chihuahua is getting can be difficult, though. But outfitting your best friend with one of the best dog activity trackers on the market can be beneficial in your quest to keep your pup their healthiest.

With a fitness tracker for your Chihuahua, you can monitor activity levels, track weight and nutrition, and even set daily fitness goals. Some trackers also come with GPS, so you always know your dog’s location. Plus, keeping track of your pup’s fitness and other health aspects can deepen your bond and increase your understanding of canine behavior.

But with so many options out there, choosing the best dog activity tracker can be tricky. Here are a few things to keep in mind when shopping for the tracker that best fits your needs.

Factors To Consider When Choosing Your Best Chihuahua Activity Tracker

Purpose

Their base reason for existence, fitness trackers are made to track your dog’s activity. But many of the choices on the market offer additional monitoring features for calorie burn, GPS-tracking, geofencing, and body composition, while even alerting you to a ramp-up in scratching and anxious behavior. But you may not need all those bells and whistles, so as you begin the search for your dog’s activity tracker, think about what health aspects you’d like to monitor.

Cost

Dog activity trackers aren’t cheap. That’s why it’s essential to do your research and know just what you need from one. But remember this, just because a tracker is more expensive than others doesn’t automatically make it better than cheaper models. Also, check whether or not a tracker offers free services or if you’ll be committed to monthly subscriptions in order to use their services.  

Range and Connectivity

Always consider range and connectivity when shopping for the best dog activity tracker. If you’re buying for location monitoring or want geofencing options, you’ll most likely need to look at GPS-powered trackers. Plus, you’ll want to be aware of what interface a tracker uses to deliver data and alerts. Does it connect with your phone or smart home system? It’d be a bummer to get a tracker and realize it doesn’t work with the brand of your phone.

Size and Weight

This one’s pretty obvious; you don’t want to hang a huge and heavy tracker on your dog’s neck. Talk about uncomfortable! Be sure the tracker or tracker collar is lightweight and comfortable in fit. Rough material or hardware rubbing your pup’s neck is no fun for anyone! 

Battery Life

And don’t forget to look at battery life when shopping for the best dog activity tracker. In use 24/7, fitness trackers use major battery power, so look for a manufacturer’s battery information and read comments to see what users have to say about the time between charging. If you’re waffling between two tracker choices, let your deciding factor come down to battery life. Less charging means less worry over a dead tracker.

Now, after studying the field and keeping these considerations in mind, here are our picks for the best dog activity trackers!
