Hi all-

I adopted a mixed breed puppy a little under 2 years ago.  She is for the most part a black lab.  [Here is a picture of my beautiful girl, Lily.]  I'm concerned that her living situation with me isn't ideal, and may be making her depressed, despite my best efforts.

Back story: I have a job where I work from home, albeit in an apartment.  When I adopted her I was living in a 2 bedroom apartment with a second roommate and a cat, who she got along great with.

Then, about 6 months ago, I had to start traveling frequently for work, and she lived with my parents.  My parents live on an older golf course where dogs are pretty much free to roam around, get in creeks and ponds, etc.  She also lived with my parents' dogs, which are 2 older black labs.  Even though they can't match her energy, she would still play with them constantly and it was a great situation for her.

Now I'm in a position to have her back with me.  I'm now living in a 3 bedroom condo with a different roommate and a small Maltese dog, who's generally uninterested in her.  I've only had her here for 2 days, but she appears really depressed.  I still work from home, so I'm literally with her constantly, and I've taken her running, on lots of walks, played with her, and taken her to a dog park.  She seems uninterested in all these things, and just kind of lays around like I've never seen her.  By all accounts she was great before the move.

I'm concerned that even though I **love** this dog, I'm doing the wrong thing by having her.  My parents also love her, and grew very attached to her, and would welcome her back in a heartbeat.  But I'll always feel a strong connection to her and desire to have her with me.
<bot>: My dog got to live away from me in doggy heaven for 6 months, and now that she's back with me she seems depressed.  Has anyone else experienced anything like this?
