Not a problem man, my opinion of your collecting doesn't really matter, and for the record I'm not judging you. If someone's willing to pay what you're asking, that's that I think.
The only situation in which I actually get very angry with selling above retail is memorial or sad commemorative pieces, and I think even that's fair if it's for medicine, food or shelter.
Anyway, glad you found a buyer and I hope your dog is on the path to recovery.
