Hi. I'm after reassurance really. We have a 3 month old rescue puppy. The rescue (RSPCA) wasn't sure what he is but reckoned he will be a medium dog and has a bit of staffy. They also felt he'd be fine with our adult cat - because of how he had behaved when with them. Anyway, everything that can go wrong seems to be going wrong. He won't sleep on his own (at the moment I'm in a room with him) and he goes mad when left alone. He is also very bitey. Not just nips, but full on biting. I'm trying to leave the room when he does it - he's not easily distracted, but tbh sometimes it's quite hard to get him off. He's not aggressive just persistent. This has me worried about him hurting the cat. This is the one thing we feel we've managed well so far. We've kept them separate, then slowly introduced with puppy on lead and distracting him. He has approached the cat when on the lead, but he's wagging his tail and looks like he just wants to play, no snarling. I'm reluctant though to take the next step and letting him off the lead. There seems so much to address and I'm losing confidence.
