Whatever17 I would be wary of taking on a dog with problems if you have a young pup tbh. Your pup will be hitting the teen phase very soon and will push boundaries. Unless there is someone experienced on hand 24/7 it could be very difficult. I have a 'teenage' dog and a puppy. I spend the majority of my day breaking up play fights and trying to persuade them not to eat my furniture.
Whether the op is bored or not is not the point. The only kind thing she could do is employ a trainer or if funds/time for that is not available rehome the puppy, who will be snapped up, whereas the older dog she claims to love, will at best languish in kennels for months, most likely years.
Lots of people have a lot on all the time. I know I do. But I cannot imagine a time where that would cause me to give up on one of my dogs. My Dad is in hospital atm. There is something serious wrong with him and they haven't got a clue what it is, so he is in to be monitored. This means I have my own two dogs to walk/train/feed. My sisters pup to walk, as she is helping out my mum by spending time with my Dad in hospital with my Dad. I have my mum's two cats to feed, one of which needs grooming daily and I am allergic to him. Then I have my Dad's parrot to feed and clean, along with his new canary, his two cockatiels, his rescued ex racing pigeons and his rabbit.
On top of that I have school and nursery runs, I am working overtime as the manager is away somewhere and I need to find out who is feeding my cat because he keeps shitting all over my house. I have made my way through a large jar of coffee in just two days. I feel like I have not slept for a month.
Coming home to my dogs and knowing I have 45 minutes of a peaceful, evening walk with them to look forward to, is keeping me sane. I would kill before I let someone take them away from me. I can't understand this mentality that when things get tough, you ease this by rehoming members of your family.
