Hope you'll forgive the beginner nature of this question. I am not a dog person, so I have very little knowledge or experience with dogs, and most of the information on the web seems (quite reasonably) to be tailored to owners and/or enthusiasts.
I will be looking after my housemate's dog for several weeks, and I know he is concerned that the dog will get lonely. Apart from taking him on walks, are there any things I can do to help him feel cared for and attended to? Are there signs I should look out for that he's not getting enough attention?
Generally while I'm around the house I'll be reading, watching TV or working on the laptop; will doing these things in the same room as him be enough to make him feel like he has company, or do I need to be engaging him more actively?
