I am a female dog and my very good friend is a horse.Is there a chance he and I could be a couple?

He doesn't seem too attracted to me like I want him to be especially when we try to engage in intimacy.we both want it,but I'm not sure what we're lacking and I want to have his full attention when he and I make love.How could I go about this.I care for him deeply and I feel he cares the same and I want to see him happy,with or without me.
