i just cancelled a weekend in Europe this weekend because I'm not comfortable with the place I was going to leave my pup...so its that kind of thing. The home boarder he used to stay with has moved so it is a massive pain trying to find a new one...
if you're going to give your dog a good quality of life it is a huge commitment - but I think if you put a support network in place it can work well.
i work at home and he goes out for group walks 4 days a week - this is so he gets a proper run without me having to worry about scheduling that into my day (I live in centre of town without a car so its an effort to go out to the country where he can have a proper run - fine for weekends but not so much on weekdays) and also so he doesn't become too dependant on me. And its good to have a break tbh because he is very distracting! He has a ball on his walks and comes home very happy. He goes out with one person three times a week and another person once a week - this is so that he is comfortable with different people and I have different people I can call on if I need help.
As well as his group walks we go for wander around the block about 15-20 minutes three times a day (first thing in the morning, about 5pm and then before bed) so he can go the toilet (he only goes in my small courtyard in emergencies) and have a sniff around.
If I'm out for a night I arrange for someone to come and hang out with him. Most Ill leave him for is 4 hours - and not regularly.
So yeah it is an organisational challenge and costs lots of money (as well as dog care insurance, food, toys, bedding....).
But provided you set up that network and are realistic about the cost OH MY GOD its the best thing I've ever done!!! I love my pup soon much and he has improved the quality of my life so much. He is AWESOME.
I do feel very strongly about the responsibility to give a dog a good quality of life though - I am very conscious that every day his enjoyment for that day is entirely dependant on what I provide for him. He has a friend who comes out on walks with him - but for the rest of the day that dog is on his own from 7:30 am until about 7:pm. So while he gets out for a good walk in the day I think that is way too long for him to be alone the rest of the day. Obviously he's not neglected and his quality of life is certainly decent - I just don't think its fair on him to be alone for such a long time.
oh also overseas with a dog (unless driving) VERY difficult.
Good luck! I can't imagine not having a dog in my life now!
