I made my first few quilts to cover chairs, so that when babies/dogs sicked on them or brought mud in from the garden etc, I could wash the quilt. Of course, they wore out, so then they got used in the dog beds (sometimes the dogs were turfed off the chairs!). I cut one up to make a coat for one dog who had heart problems and was always cold.
I have given quilts away, always with the strict instruction that it must be used. I have sold them, on occasion, though I discouraged the couple who wanted to use one as a hearth rug in front of an open fire, by pointing out it would burn (I didn't hand quilt it for that!).
I think one of the main reasons for quilts not getting used is duvets. You don't really need another layer on top.
Quilts are very useful in the summer, with just a sheet if you want. Lighter than a duvet, and heavy enough to stay in place. I have seen bed runners ('those coloured strips across the end of hotel beds') used in hospices etc, when people need a little extra warmth across their feet.
Oddly, my dogs never chewed a quilt - and whippets are notoriously destructive - but the chewing stage is fairly short, just put things away if you're not there to supervise.
