I think he works very long hours and you support him to do this so its a bit of give and take here. My hubby would not have dogs if i wasn't here but i kind of made it clear that I am 'me' and i come with 'dogs'. No Options on that! If you used to have three I can't see why you can't go back to three. Just get the dog. He can't object if you are doing all of the work!!
