I have 3 little ones & each one has this harness in a different color. Minnie is the Mom & hers is red, Vinnie is the Pop & his is royal blue; and Bruiser is their Baby & his is royal purple - ya know, combo of red & royal blue!
I use the harnesses most often when I take the pups in the car. I have a leash rigged up (I have an SUV & looped a nylon leash through the cargo holder and connected a couple of 2-dog connectors to the other end) & then hook into their harnesses. Hopefully, I'll never get into an accident, but I know if I do my little dogs won't go flying around in the car!

Pros: Easy to put on

Cons: Not a training tool

I purchased this item in Royal Blue and found it easy to fit to Jo Jo. I love the way it fastens to the seat belt and length is adjustable.
She was comfortable with it the first time she used it and alternated sleeping and looking out the window.
I love knowing she is safe in the seat and there is no worry that she will sneak out when the first door is opened.

Pros: safe, inexpensive

Cons: matching leash would be nice

We have this harness and Abbey loves the pink. It comes in lots of colors but she likes pink. Since we got it she walks so much better she use to pull now she prances...

Pros: Love the pink fits good

Cons: none

I tried this in every size but they do not fit my dog. She slips right out of it. It was not safe at all for me.

Pros: Doesn't fit right

Cons: Not a good fit

I have the pink one too and I love it coz it so easy to use n make her easier to handle.

Pros: Loves it coz it wont choke her

Cons: none
