Hi
Fenris is 12 weeks today ,he is a GSD.
I have not changed his routine but he has suddenly turned into a horror
He seemed to be doing very well with his training etc , toilet training was going well .Then on Saturday the weather here was vile , heavy rain high winds .I kept up the routine of short walks and into the garden at regular intervals but he would not wee or poo .......then would comeinside and do it in the house !!!
Yesterday he was the same , although the weather was better

, I am going to bo back to basics with the toilet training see if that helps.
Also he has suddenly become really naughty , nipping all the time and generally taking no notice at all

...............The whole sitting etc has gone out of the window ! He even bit my finger and drew blood yesterday when he was getting a treat ..........normally he is quite gentle .
I am at a loss
Any suggestions please ??
