Red, blue, pink and orange collars. Pink seems orange at night. In comparison to red or orange, blue is nice. My favorite color is orange. I haven't tried the green or yellow yet, but I'm sure they'd be easy to see. Buying numerous colors allows us to keep track of multiple dogs in a dark park or night activity. So I may comment on the colors.

I bought the leash first, then the collar (which is the greatest glow leash I've ever owned). The collar is fantastic too. After work, it's dark, so walking my dog seems safer. The collar isn't flimsy or cheap, and it charges quickly and lasts long. I don't use the flashing collar, but I appreciate the possibilities. I should've ordered the green because my current leash is green and quite bright, but this one is nice too. My only downside is that it's huge on my dog and doesn't adapt nicely (mostly my fault for not measuring). Its range of adjustment is limited. Regardless, I love it and will definitely buy another one. It's a bit slack on my 90 pound German Shepherd.

Just what we needed! a little black dog and a large backyard This stops me from panicking if he stays out late at night to scent the breeze. I bought a small for a 15 pound Lhasa. I should've gotten an extra small because I had to tweak it a lot and it's still loose on him. But it serves our purposes wonderfully. That was a gift I purchased myself.

This collar is perfect for our two puppies now that the evenings and mornings are growing darker. We have one in green and one in blue, both BRIGHT. It provides us peace of mind knowing we can watch them at all times. It's like going to a rave in our backyard, which has added a lot of fun to our evenings. It's been fun to watch two glow sticks run and wrestle. Beyond that, we know they will be seen by others, which is a built-in safety feature. We haven't utilized the leashes yet. We'll need these for walks once daylight savings finishes. Also, I definitely recommend the leashes!

My dog and I walk 2 miles after work. Even with my lights, our evening treks have startled several. This was my ideal solution. It's a great collar! It's bright enough to see her from afar but not so bright that it bothers her. It has three settings, but I only use one. I also use a harness to avoid tying the leash to the collar. Like that it's rechargeable and I don't have to worry about batteries. I also wear it when we visit my sister's house and she is out in her larger yard. I don't need to go out with a flashlight to find her. I would and have suggested this product to other dog owners. It's fantastic!
