It sounds as if your poor poodle was badly matted (common in a rescue dog)- for the burned bum- you can use some neopsorin, and you can try some baby powder. Find another groomer- ANY groomer should know better than to use a hot blade near a sensitive area- it sounds as if this groomer was either lazy or rushed, and used a hot blade. It's easily preventable!
The nickes are common if the dog was matted, trying to get through the mats is difficult. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
