Please don't get the dog if that is the case. Dogs are highly social animals and putting them at home all the time is as good as locking a person in the room all the time with nothing to do. Ask yourself first, what do you want the dog for if you are not around most of the time. The dog will get mentally sick and disturbed if locked at home alone for long periods.
My friend in Australia had a pomenerian which he bought for his gf when she had one of her "I want" whims. The poor fellow was neglected after she got bored with it and was often locked up in the house alone. Being lonely, it became abit possessive and everytime my friend wanted to go out, he would get really excited or rather afraid I would say of being left alone and start yapping and running around my friend's legs. My friend also quite an ass**** would kick his dog away and shout at it to get lost.... sigh......
After I offered to baby sit him when my friend went back to HK for 2 months, it took me some time to undo some of the damage he did...... Constant hugging and sweet talking to the bugger..... and everytime I needed to go out. I would switch the TV on, and talk to the dog. Yes literally talk to him like a human and say "Im going out for lunch, be a good boy and watch tv okay?" The funny thing was he didnt go barking at me like he did to the owner but actually sat on the sofa and walked the box!! Then also no matter where I was in the city, would rush home before sundown to switch on the lights for him so that he won't have to walk around in the dark at home...
So to the gentleman and his wife who are not at home most of the time but want a dog, are you prepared for such responsibility or will you be one of those handing over the dog to SPCA after 3 months?
