When I bath my Beardie Bent, (she is a rescue with a tail that goes at a right angle and a foot that is sort squished up) she is about 4-5 months old, I support her in the water and every once in awhile i feel her heart or somthing like a hiccup that beats once real hard and makes her whole body shake. Otherwise she is a health happy girl. Is this something that I should be concerned about. I am wondering If she has a weak heart due to her birth defects. Or is this just normal behavior?????
