We got a rescue puppy at new year. We got her at 10 weeks and by 12 weeks she was housetrained. BUT, a large part of this was because I am here all day and my children are at school, so I was able towatch her like a hawk. She also goes in a crate at night or if I have to pop out. If she was left for a long time in the house alone, I doubt very much she would be able to hold it. So that restricts you and your mum going out for the day as puppies really cannot be left for long.
The training is definitely an ongoing thing. They need puppy classes and several bursts of training every day. My DH works full time and is able to do a little with her, but only in terms of practising what I have taught her. I cannot see how someone working full time, then going to th gym regularly will have the time to properly train a puppy.
A lot of the training takes place outside of the house. So going to new places, coping with traffic noise, meeting dogs and people. There is no way I could have done this with our puppy after work as she is asleep for a lot of the evening, especially when we first got her.
The dog would need to be trained to walk properly on the lead. Again, this needs reinforcing every day. That would not come down to your brother if he is not home, it would be you and your mum.
Puppies have to be watched constantly. They eat anything (including their own poo) and really need saving from themselves nost of the time.
I have also not had a full night's sleep at all in 2013, as my puppy cannot yet go all night without the toilet and barks (well yaps!) to go out.
I am shattered, but because I have the time to put the work in, we can see it all paying off already. If I was at work all day, I would still eb shattered from the lack of sleep, but also I would have an untrained dog.
I also thought greyhound. The ones we see on our walks are going so slow they are almost going backwards!
