Knowing the safety it brings I would highly recommend!

Very happy with my purchase of the DogFender collar, have used it for a couple of weeks and have really noticed a difference in how I have enjoyed my dog walks, knowing the safety it brings. Would highly recommend for other dog owners!

Makes my walk stress free….

Love this collar. Makes my walk stress free as I have a small terrier who frightens easily. It gives me peace of mind. It’s well made. Love the night lights and now it’s a must for every walk.

Simone Shaw

Glad my dog is safe now!

This has been needed for so many years!
Glad my dog is safe now!

So glad that I invested in this collar.

I have a small dog that is nervous and anxious and so I decided to give a Dogfender collar a go. What did I have to lose as I adore my little man. Obviously, it didn’t give him piece of mind but it did me because I knew that my dog was protected with a press of a button. No use of the night lights yet but sadly autumn will soon be upon us. It’s great to have all these features in one product. So glad that I invested in this collar.

Sue Hodgkins

Easy to use and makes me feel at ease….

Fantastic collar, fantastic invention, easy to use and makes me feel at ease when taking my dog out. She can be quite nervous and has had a few dodgy encounters, but nothing too serious, and when you’re too far to stop anything, it’s scary. I did try this collar and I did set it off when a dog started sniffing round her, but luckily nothing happened, though I did feel more at ease with her having the Dogfender Collar on. Brilliant invention!!!
