Just to back up what has already been said, our Staffy/Lurcher pup Loki has been a real nightmare. We knew having a pup woul dbe hard, but it has been truly awful, and I have been practically tearing my hair out constantly since we got him.
But, he's 5 months old now, and although toilet training is still a bit hit and miss, he's becoming a beautiful little dog. He's not as manic as he was, sits on command, and he will sit at your feet and offer you his paw bless him, doing that daft floppy eared, head on one side thing that pups do so well!
It really is such hard work, but then your pup will do something really small and insignificant, and will totally melt your heart, then it will all seem worth it.
It's like living in a cartoon in our house, it's so manic all the time, but I wouldn't change it for the world............
