Starting this thread in the hope of tips and support from people who've adopted a young dog without much domestic experience! I think we're pretty much ready, but who knows what will come up.
We've always had corgis in my wider family and recently lost a young male to a rare genetic disease. It so happened that the local dog rescue has a young male corgi that badly needs a home. We met him yesterday and he's coming home in a week. He's a very exuberant, very long, very skinny, not very domesticated young man who needs training and learning to live indoors. He's quite charming, but presently gives the impression of something like a wild scraggly fox. No idea how a valuable dog like a young corgi ended up like this - possibly a dumped by a backyard breeder? He definitely needs neutering and will be done as soon as he's gained a bit of muscle and condition. We have a female corgi at home and they mostly got on fine, except he of course tried to mount her and she told him off. No violence, just warnings - neutering should end this. Otherwise they were quite happy together and even licked each other's faces.
Despite being underweight and in poor condition, he's very hyper and bouncy and desperate to run around and play, but of course has no leash training and no recall. The primary adopter (who lives around the corner from me) has a huge enclosed garden which is a good start.
