Our puppy is nearly 6 months old, he's an Old English Sheepdog called Benji and he is lovely! We also have a bichon frise, Alfie who is 4. We always give both of them fuss and love, but when Benji sees us giving attention to Alfie he starts barking. We pay attention to both of them at the same time but Benji really doesn't like it when we he sees us stroking Alfie. Also, Benji sometimes gets a bit playful, I know he's still a pup but he gets bitey and keeps barking. Any ideas on how we can get him to calm down a bit? (He was castrated a couple of weeks ago). Thanks
