Questions & Answers

29 Customer Questions

What is the abrasive buckle for and the conductive silicone cap for

Does this collar offer the automatic bark deterrent feature while still allowing manual control for other behaviors?

Answer by Chewy • Oct 21, 2021
This training collar must be controlled by the remote. It does not have an automatic bark deterrent.

Is it waterproof?

Answer by Chewy • Oct 11, 2021
This collar is waterproof and suitable for training in rainy and snowy days.

It says waterproof, so If the dog is swimming, the collar will still work if needed correct?

Answer by Chewy • Dec 30, 2021
While this is designed to be waterproof, it is recommended by the manufacturer to take off the receiver when your dog is swimming.

Escape prevention

This works great! I’ve been using this for a couple of weeks with my stubborn escape artist beagle & has worked perfect. I have used the beep mode & the vibration

This works great! I’ve been using this for a couple of weeks with my stubborn escape artist beagle & has worked perfect. I have used the beep mode & the vibration mode. My doggy comes right to me when I’ve had to use it so I haven’t had to use the shock mode.

Great Range and Easy to Use for Daily Training

This collar is very easy to set up and use. The remote is intuitive, and switching between modes is simple. I love that I can adjust the intensity to match my dog’s

This collar is very easy to set up and use. The remote is intuitive, and switching between modes is simple. I love that I can adjust the intensity to match my dog’s needs instead of using something too strong. The 3,000-ft range gives me confidence when we’re at the park or in open areas. Training sessions are smoother now, and my dog clearly understands what’s expected. Definitely a reliable training aid.

I like that I can just beep it and he dont run out of the yard.

Everything is good just if I walk inside a few minutes he runs to the neighbors yard. So you have to stay outside if you want him to stay in the yard Hes young hopefully

I have a hyper Australian shepherd and jumps on everyone including kids and also gets a little rough with my goats and this collar is perfect to get her to stop that behavior. Has 4 modes a shock or vibrations or you can use the beeping mode. This has helped out so much now that my daughter can go play out in the yard with her

Not as advertised.

This collar only works up to 200ft. That’s if it will work. I have charged the collar and remote several times and it only works half the time.

Great Shock Dog Training Collar

Got this for one of my dogs that seems to have a problem with obeying to my commands. So far two days with this device and it seems to be working. He's more calm

Got this for one of my dogs that seems to have a problem with obeying to my commands. So far two days with this device and it seems to be working. He's more calm and seems to be listening to my command. The vibration and beep on it work well.

Easy as pie

So glad my dog won't pull me off balance anymore. This collar comfortably fits and gives just enough reminder without it being overwhelming.

Excellent Training Tool! Highly Effective and Reliable!

I’ve been using the Petdiary T720 for a few weeks now, and it has completely transformed my dog’s training sessions. My pup is not bad, but she is a rambunctious

I’ve been using the Petdiary T720 for a few weeks now, and it has completely transformed my dog’s training sessions. My pup is not bad, but she is a rambunctious one year old Cane Corso, who thinks she weighs 5 pounds and that everyone is her friend. With some people having a fear of big dogs she needs to be under my control at all times, this way she can run and play off leash without the worry of her getting into trouble. The 3,000-ft range is a game changer, allowing me to correct and guide her even when she’s off-leash. The collar fits comfortably, and the adjustable strap ensures it stays secure without irritating her neck. The remote is very user-friendly, with clearly marked buttons for vibration, beep, and shock modes. I really appreciate the multiple levels of intensity so I can tailor the correction. The waterproof feature has already been tested as my pup is a swimmer and hits each and every water puddle, and it worked flawlessly. Battery life is impressive, I only need to recharge every few days despite daily use. For the price, the build quality feels sturdy and long-lasting. If you’re looking for an effective, easy-to-use training collar, this one delivers exactly what it promises.

Poorly designed strap, vibration and e-stim are way to strong

Collar was too flimsy to get stay at the correct tension, vibration and e-stim were much too strong at the lowest setting to properly use as a training tool
