A woman that I'm reasonably friendly with has 2 dogs. One was her now dh's dog when they met 10'ish years ago.
I thought he was an old dog then turned out he was less than a year old. He was slow and overweight back then he was rarely walked and escaped for a wander any chance he got.
Fast forward to last year they got a springer spaniel now about a year old.
He is a beautiful dog has all his papers so not cheap either.
The problem is he's never (and I mean literally never) exercised. He is a typical springer full of energy and because of his lack of exercise a total pain in the bum. Mil had a 9 year old springer that gets more than her fair share of exercise and would still never refuse more. 
This dog cannot walk on a lead. I have given up my own time at friends request to help get him exercised and trained but once I stopped doing it after getting her started so did she. It's so frustrating to see him. He is now their second dog that bolts every chance he gets. He is constantly bouncing off the walls all day every day. Is not properly house trained either.
He gets 10 minutes tied to the washing line if he is lucky and that's it.
I was talking to her dh last week and their new solution is to build a 6 foot fence to stop him escaping rather than take on the commitment they made to the dog and actually exercise him properly.
I ended up being quite rude to her dh and told him to re-home the dog if they weren't prepared to look after it properly. I was just so
he said that we would have to agree to disagree. It's not a case of which is the best bloody dog food to me this is a basic commitment when taking on a dog especially one that needs that much exercise.
Gee whizz that was a longer rant than I meant it to be. Is there anything more I can do. I would happily report them if I thought it would make a difference. I feel so bloody sorry for him. He's got a great nature and is lovely but he's absolutely desperate to run off some of that energy.
