In November I adopted two no determined breed puppies who were about 9 weeks old. Although they did not look alike, my feeling was they were siblings. WE have had several power outages in our area and despite having two gates barring my property the puppies were able to get out and sadly the female puppy was killed.

The puppy that is left behind is pining and is pooping and piddling inside at night. How am I able to retrain him to rather do it outside on the grass. He has access to the outside. I realise he is feeling the loss as much as we are.

I do hope you have bought a crate, to assure the other puppy doesn't suffer the same fate.
