Why would she still charge you the same price for a 2 year old dog as she would for a puppy? Seems to me the price should go down... especially since you're now going to have to deal with his marking etc. Not to mention, just because she didn't have any success with breeding him, doesn't mean he's not going to be a humping machine...
I dont think it's too late to try to train him - might be more difficult than with a puppy since you're not working with a clean slate... but I'm sure it can be done. Ultimately it's up to you - but if it were me, I'd be looking for at least a small price reduction. |
