Having a 12-year-old dog, I've used many many different types of poo bags through the years. I like these particular bags for the following reasons:
* they have a pleasant smell without being overwhelming.
* The box which allows you to dispense them one by one, is very helpful.
* they're better for the environment than bags that are not environmentally friendly.
* they're a good size and are strong enough to do the job without splitting or breakage.
They are slightly frustrating to open, sort of like the plastic bags in the produce department at the grocery store. But I figured out a way to get them to open pretty quickly. If your finger is a little damp they slide open a lot easier.
When I run out, I will order more of these.
