How SensorSafe™ Works:
Originally developed to help prevent the rising number of infant hot car deaths, SensorSafe will chime through the installed vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off. This reminds the caregiver to act quickly, but if the child is still secured after several minutes an alert will be sent to the caregiver’s cellphone through the downloaded app. If the situation is still not remedied, the designated emergency contact will receive an alert with the GPS coordinates of the vehicle’s last known position. This state-of-the-art safety technology is designed so there is no need to reinstall each time you drive - just keep the receiver plugged into your car’s OBD port to drive with that extra peace of mind.
- Chimes through the installed vehicle receiver if child is still secured in the seat when the car is switched off
- Alerts through the caregiver’s cell phone if the child is left behind in the vehicle and then alerts the designated emergency contact if the situation is still not remedied
- Emergency contact receives GPS coordinates of the vehicle’s last known position
- Alerts through the vehicle receiver and caregiver’s smart phone when the child has unbuckled themselves while the vehicle is in motion
- Monitors the back seat temperature to alert through the vehicle receiver and the caregiver’s smart phone when the back seat appears to be too hot or too cold for the child’s comfort
- Provides warnings to the caregiver when the child may have been seated for too long and needs a break
- Receiver plugs directly into your car’s OBD port and syncs with the caregiver’s cell phone
- Only one install needed if receiver is kept plugged into vehicle’s OBD port
- Helps to prevent misuse by providing guidance on installation, how-to videos, FAQ’s, direct link to customer service and more through the SensorSafe app.
- App can monitor up to 16 chest clips on a single platform
- App download available for Android and IOS
- Anti-rebound design reduces car seat rebound movement by nearly 30%
- Highly visible indicators change color when the car seat and load leg are properly installed
- Height-adjustable load leg stabilizes the car seat and can reduce crash forces up to 40%
- One-hand release buttons for easy removal of the car seat from the base
- Dual Level Indicator ensures the infant car seat is reclined at the proper angle
- Unique belt tensioning system offers simple and secure LATCH and vehicle seat belt installation

Perfect for Our Nervous Rescue Dog
Size: Large, Color: Green
First Impressions
I bought the Pupsicle for our new rescue dog who was very nervous whenever we had to leave the house. Right out of the box it felt sturdy and well-made, and I liked that it wasn’t just another cheap chew toy.
⸻
Setup & Ease of Use
I went with the premade treat inserts to start, which made it super simple — just pop one in and hand it over. It’s also dishwasher-safe, which is a huge win for me since I don’t want to deal with scrubbing peanut butter out of toys.
⸻
Performance in Real Life
She loves it. The Pupsicle has kept her occupied and calm, which has really helped her acclimate to her new home. Instead of pacing or whining when we leave, she settles down with this toy and stays busy.
⸻
Pros & Cons
Pros:
• Helps reduce anxiety for nervous dogs
• Very durable and solid
• Easy to clean (dishwasher safe)
• Premade inserts make it effortless
Cons:
• On the heavier side, so probably best for medium+ dogs
• Inserts are convenient but add a little extra cost
⸻
Who It’s For
Perfect for new dog owners, rescues, or anyone with a dog who needs a healthy distraction when left alone.
⸻
Final Verdict
The Pupsicle has made a noticeable difference for our rescue pup. It’s durable, easy to use, and has genuinely helped her feel more at ease in her new environment. Highly recommend.

Dogs love it, hard to open and close
Size: Large, Color: Pink, Size: Large, Color: Pink
My dogs love this toy. It keeps them entertained a long time. Great calming toy for when you leave the house. Only issues is it is very hard to open and close. One of mine I had three people try to open and after fighting with it for about an hour I finally got it opened. Got 2, one a blue and pink one for each of my dogs. The blue is easier than the pink but still hard to do. Just not as bad. Can't close the pink all the way because it is so hard to close. The dog that uses it has trouble getting the stuff out of it. But it doesn't stop her from trying for hours to do so. Does get some teeth marks on it as well if they are aggressive chewer. Tried multiple eatable lubricating substances to try to make it easier but so far nothing fully worked. Aloe Vera has worked the best so far, but not great.

Good in theory, but didn’t fully deliver
Size: Large, Color: Green, Size: Large, Color: Green
My dog falls right on the size cutoff between the small and large Pupsicle. I initially ordered the large since he’s a strong chewer, but he had trouble getting everything out, so I ended up trying the small as well.
There are definitely some positives. I think the design is better than a Kong. It stays upright, which makes it less messy. I also really like the mold for making the inserts, instead of having to fill the toy itself and freeze it.
That said, there are two major design issues that impacted my experience. First, the all-rubber construction creates a lot of friction when screwing the bottom into the base, especially after repeated use. It gradually became harder to open, to the point where I was using coconut or avocado oil to try to loosen the threads. At one point I even needed a wrench and pliers just to get a better grip.
Second, while it’s marketed as dishwasher safe (which I was excited about for cleaning), it seems to dry out the rubber and makes the threading issue worse over time.
Unfortunately, mine is now permanently stuck shut and no longer usable. Overall, I like the concept, but the durability and usability issues make this a 3-star product for me. I’d recommend it with caution, especially if you plan to wash it frequently.

Cute toy and well made
These are very cute and so far my dog has not destroyed them and he’s a very aggressive chewer. They are great quality. The colors are vibrant. Rocky loves the squeaker. They're light weight and the perfect size . He enjoys playing with them. We like to take them when he’s not looking and throw them to watch him go fetch them.
