Hi all, my partner and I have a four month old Chihauhua cross Pomeranian. He's usually got a sweet temperment and is friendly with people and dogs. We also attend puppy training classes where he's doing really well too. In the last couple of weeks we've seen a change in his behaviour - he's become territorial and protective over us and his food as well as the area he sleeps and has shown aggression towards us and our cat. He's also developed execessive barking at noises when we're around but I've noticed that he doesn't tend do this at night or when we're out of the house. Please can anyone offer any advice for us as we'd like to correct this behaviour whilst he's still young.
Many thanks
Jenny
