Query: Not ideal but it will do

This car booster seat seemed promising at first, but there are many pitfalls. My rat terrier (7 lbs) is very crowded in the car seat. There is enough room for her to sit but really not enough room to get comfortable. The car seat was a hand-me-down from a Havanese (think Shiz Tsu) who was WAY too big for the car seat. The car seat gets hot. Very hot. There's not enough room for the dog to have a chew toy or anything to keep her occupied. It's not difficult to assemble, but it is difficult to dis-assemble if you need the seat. And lastly, one of the clips broke. So the seat cannot stay propped up, it sinks to the base of the chair. The car seat works fine as a place to just lock your dog in, but the dog can't see out the window.
