I can not believe that this was done by a vet!!! The pictures brought tears to my eyes immediatly. This is soooo sad. I hope that they are giving him good meds so he is not in too much pain. Your friend should call the humane society or ASPCA (The American Society for the Prevention of Cruelty to Animals). This is the website. There is a link to report animal cruelty.
www.aspca.org We will keep him in our hearts and pray for a speedy recovery.
