I feel for those with injured pets. It is so hard to see them suffering and in pain. We used a bath towel as a sling when Cassie tore her ACL, but she was lab sized, not a Dane. I cannot imagine having to help lift a dog that big.
My giftee has pets, I will have to plan something special for them. I am concerned about putting pet treats in the box. I know my cats and dog would rip into it when I was at work.
