My 5yo Dobie is 'chattering' too. Seems like it is tooth grinding, I just had her teeth cleaned bc she is missing 3 teeth in a row on her left side. The vet and I are stumped at what caused the tooth loss. The current theory is that it is partly behavioral, and partly allergy. I use a Halti to walk her, otherwise she pulls my shoulder out. She HATES the Halti and will try to rub it off. The vet believes the degradation product of the nylon caused an allergic reaction, she started to dig at her mouth, but anxiety/OCD/being a neurotic Doberman caused her to keep digging. There was very little tooth plaque and no gingivitis or gum issues that would have caused tooth loss.
I was originally under the impression her 'chattering' was due to being cold since it often occurred when the AC was on. I just noticed her teeth 'chatter' for the first time since the cleaning last night. I know low thyroid can cause issues with temperature regulation and intolerance, hair loss, weight gain, etc. I'm currently trying to figure out if low thyroid could lead to tooth loss.
