Hello I bought a 6-7 month old puppy JRT to our home 3 months ago, he is now 9 - 10 months old, and has adapted well to our lifestyle, he is not neutered, but he is still very anxious when we leave him, and has taken to chewing my hall curtain and barking/whining. We have removed it, but WE are anxious he will find something else to chew. Will he grow out of this ? When he is put in a crate, he barks all the time we are out, and pulls at the bars, bending them. I had a Whippet/JRT for 15 years previously, 8 years ago, and he did grow out of the chewing/whining/barking I dont work now, so I am at home a lot, whereas with my previous dog I worked full time while he was a puppy ! Any tips would be great, my dog is good in a lot of ways, a quick learner, quite obedient, but really boisterous, as you would expect from a pup.
