My seven month old puppy has been calm all day, unusual for him, hasn't eaten all...

[Mandi]

...day, and is completely dull.? What I'm asking is, what is wrong with him? He's a german shepherd, my mother thought he might be depressed since we just moved and i haven't gotten to play with him much and now since we're renting i'm not allowed to bring him inside, so now he doesn't sleep with me. But Just for the past few days out of a week i've not been able to go outside and play because i'm sick. But just yesterday my boyfriend and him were running up and down the street. And today, he's like i said dull. Then as i took him to the bathroom outside right now, he went pee, but oddly from his 'poop hole' he pee'd? It looked like blood but could have been my imagination. what's wrong? :[
