This one is for medium-sized cans:
I've not used the new top design yet. Mine has a lid that you have to take off. The new design sounds better yet.
They said, I noticed, that the first time you use it, you have to use extra pressure to break the seal on the new design top. Maybe you'll want to do that outside with Charlie in the house.
You know...you might want to consider taking one with you to the mailbox. In case of aggressive dogs, or even a wild animal.
The usual safety warning that are with all things under pressure apply...don't puncture, leave in a hot spot like a car, etc.
We used it behind our backs at first. He figured out that we were behind it as he got older, and now, as I say, just seeing it works. Just like the spray bottle. We haven't actually needed to spray it for quite some time.
Love All Life, Thank You For Posting! :)
