Thank you all for your input. And I'm sorry for not having read your beautiful post about how to take good hoof pictures "Loosie" last week when I looked at the horse.
Indeed, those are only the two hind hoofs - the two front hoofs didn't look that bad so I didn't take pictures of them. Maybe I should have. The problem is that the guy who sells the horse does the trimming himself - and as you can see he is not doing the best of jobs. So if I ask him to give the hoofs a good trim before I decide to buy...hm...not sure if that's a good idea.
I like the rest of the horse - I just don't want to buy one if the hoofs will cost me more than the entire horse afterwards.
I've attached pictures that show more of the horse - they are taken out of a video I took while I was there (yes, she is overweight). My apologies for not having the best of quality. Also sorry for the cropped pictures - but it's not my horse (yet?) so I don't feel comfortable putting much online of her.
Thank you all ever so much for your opinions
