Having had dogs all my life, I have to say OF COURSE this has happened to me.
I used to have one who took shoes and chewed them - boy, did that make me mad!
And yes, I still have an 8 year old whippet who "pinches" thing, runs around with them and then dumps them somewhere.
Very annoying as I find things in the backyard and scattered around the hosue. She does it when she gets excited -many mornings when I start to get ready to go for our walk, she grabs something, run around with it for a few seconds and comes tearing back to me.
I haven't, but a friend of mine left her false teeth on the side table one night.
Needless to say her very large dog, took them and dug a hole they are quite sure, but the teeth were never found.
BAD DOG! :(
I have two cats and they have never done this before. I think it is more something that dogs would do. The neighbours dogs don't ever come onto our property. Sometimes we get the occasional cat come into the property. Our cat is a fierce protector of our property, as it is his territory, so other animals don't often make the mistake of coming into our property. He has been known to chase dogs halfway down the road !
Cats are notorious clothes stealers. I have never had this happen to me nor have I had animals that did, simply because mine are not allowed off the property. I did, however, know a neighbour's dog that used to steal their neighbours HENS!! It was hysterical. He loved them and he would take one home and lie under the porch with it until they took it back and then he would take another. He never hurt them at all . . . .I think he got lonely. LOL LOL He was a real sweetie. (no Retriever in him either.)
