At my first sitting I think the dog is wearing a cameral collar, I was not informed. Should I text the owners?
I personally don’t feel a camera is out of lines. If the pets you’re sitting will be near you or in bed with you at bedtime then t would remove the collar at that time and replace in the morning when you are up and dressed for the day. Explain to the owners when they return that you appreciate their diligence but you value your modesty and privacy as you’re sure they do as well. Otherwise, if you are providing services as advertised, the camera can only help.
Maybe this contains a typo and you mean camera collar?
It’s up to you if you want to contact owners right away or discuss in person when they return.
