I just reread this vintage advice from wonderpuppy.net. She talks about how important it is to adjust a cart correctly and encourages people to contact the manufacturer and send photos when trying to get the adjustments right. She says if you have a fluffy dog, you may have to wet the coat for them to be able to see what's going on.

Please, if you put your dog in a cart, send photos to the manufacturers to check for fit, an ill fitting cart of either type can really cause lots of problems. If you have a furry dog and take photos for the cart company to check the adjustments, it may be easier if you soak down the dog first! The poor folks at Doggon had a tough time seeing what was going on through all of Copper's fur until I took photos of him in the cart while wet.
