I have a dog stroller for my 13 year old cavalier. She loves go for walks with the other 2, both 4 year olds, when she gets tired I put her in the stroller. It's one of the best things I have ever bought. I could not stand to leave her home. Sometimes I put the other 2 cavaliers in, if they get tired.
I have the Pet Gear AT3. We all love it.
