Look, I think you're all being very insensitive. Instead of taking the piss, we should respect Goldie for coming as far as this. It takes real guts to do what Goldie has done, and although we may not agree with his motives, we should applaud the courage it takes to get this far.
This comic scenario is obviously a metaphor for Goldies' real life problems. In the same way an abuse victim will use puppets to describe their suffering, Goldie has used A2K to vocalise his, (what some would call perverted), desires.
Goldie is obviously dog-**** curious. It's not something I'd recommend, but if that's what Goldie feels he needs to do well so be it. Just make sure the dog consents, and give her a biscuit afterwards. There's no question it will be a female dog, there's nothing funny about Goldie.
