When I got Lemmy, I figured I'd have to adjust things to accommodate him only having one eye; He had quickly proved me wrong, and I didn't have to provide any special treatment.
I got so use to him being his corgi-self, I easily forget his "handicap," until recently when I went to take him and Pilot for a walk together.
Countless times I walked into him, he walked into me and Pilot... I felt sorry for him for the first time.
The good thing is we've been working everyday; Lemmy always looks up at me, big corgi smile on his face, tongue hanging out, when he knows he's doing good. He pays attention to me, and he's slowly learning to focus on me and trust my lead.
He's still jumpy/ anxious when he can hear something or when something shoots by him. I remain calm and praise him when he keeps walking.
If he's taught me anything, its there are no excuses not to live life. He has one eye, and he fraps, destroys, loves, and lives his life like any other corgi: To the fullest.
