He would n't play at all , he ran from his tennis ball , and would hardly acknowledge the frisbee I brought him ( He used to be MAD crazy about frisbees ) . He 's gained weight , and was just ... not himself the whole time . It really made me upset , and mad that I ca n't have him with me .

Question: Why are you unable to have him stay with you ?
Answer: None of the above choices .I live in an apartment that does not allow us to keep pets so he stays with a friend of mineI have a cat now and he does n't get along with the cat so he stays with my friendHe prefers my friend with whom he is staying so whenever I come to play with him he seems to be disinterested in me
