Hi ..... first time I am mum to a boxer. My 17 week old little girl has started to make a clunking / clicking noise with her jaw. It's only occasionally, and just seems random, ie:not associated with yawning, or chewing. She eats with no problems and doesn't seem bothered when chewing toys, tugging, etc, and she is happy for me to gently manipulate her mouth. She also does not have an overly pronounced underbite .... it is there, but you don't see her teeth when her mouth is closed. Just wondering if this is usual in boxers at this age, when teething is starting, or something I should be concerned about and take her to the vet.
