I agree with the pad on the bed....they are sensitive to pain and that alone would immobilize them for awhile.
Max would be no help....just today, I took him to Petsmart for dog food...within 1 minute of entering the store, he lifted his little leg on the big feet of a Boxer......had to clean up the floor and the dog.....
THEN...a roofer was giving us an estimate this afternoon and Max marked the man's shoe.....
Then I walked over to our new neighbor who was standing out in the yard.....I took Max as an ice breaker, friendly neighbor to neighbor kind of thing and he hunched up and delivered a 4 inch poop right in front of her in her yard! I was so embarrassed....he has been an elimination factory all day. If he wasn't so darn cute, sweet, loveable, loyal and huggable....he would be out of here!
