Hi I was wondering if anyone has experienced anything similar. My boxer yelped a few months ago when I was taking her collar off over her head then constantly yelps when picking up a toy she used to be so playful with toys and played rough with them and now won't pick one up or play with it without yelping . She is eating drinking normal no pain. Her jaw is stiff when she is yawning and looks like she can't open it properly to yawn. The vet has no clue as teeth normal and no swelling / lumps ect.. 3 months later we are still in the same situation. Anyone else had anything similar to this?
