New Bedding

My blood pressure shoot up above normal last night. Our pet who already knew some house rules accidentally peed in our comforter and it goes down to our bed foam. I immediately washed and disinfected the corner side of the foam of our bed and blow dried. I was really mad having a hard time communicating to our pet and letting him understand not to pee again. He has been with us for over two years now and this was the first time he violated the house rules. I felt that he was scared of me. I can read in his eyes that he's asking for forgiveness, but no! He is now grounded and will stay inside the dog crib for a day or two until he learned that what he did was something foul and against my rule. I wonder why he found our bed to good for peeing. Or maybe it's an indication that I should purchase new bedding now. I've been wanting to buy allergy bedding to give us maximum comfort. I didn't get enough sleep last night. We slept in a hard mat and woke up with a stiff and aching body.
