According to the rescue I adopted from, Cece is somewhere around a year old give or take a month. The last few days, her behavior has changed pretty noticeably. Normally, she doesn't leave my side, but she has been spending a lot of time in her crate. That alone wouldn't have me concerned, but she's been whimpering quite a bit and chewing on her bed, something she's never done. She can be a little mouthy, nothing aggressive just playful, but she's gotten a little more persistent about it. She's eating normally and will initiate play, but when she's whimpering in her crate, she refuses to leave. Is it possible that she's still teething?
