A lady that goes to the same groomer as I do has one...she has a pomeranian and our groomer told me to see how happy the dog is...personally, I don't think the dog looked happy at all...to me, he seemed miserable...I just think since the owner is giving him no choice, he's just used to it...I just think it's uncomfortable...she said she also uses it in the car on him....just hangs it on the back of the seat....I don't think dogs like their feet hanging in midair...whether supported or not, especially for a long period of time...
If anyone chooses to get it, I would just say...definitely try it out first...
