[help] we've noticed our 3 year old yorkie-Pomeranian dog has been exhibiting "fabric sucking" ever since we had her spayed last year. Has anyone experienced this?

She's never had destructive chewing problems before. We don't believe she was weaned too early. The fabric sucking and chewing literally started happening days within being spayed. I couldn't find anything from google so I'm wondering if you guys have any opinions before I look at professional help, as ASPCA suggests. via /r/dogs http://ift.tt/2qyx88d
