I am one of the posters here who has cried tears, oceans of tears over our puppy. He's now nearly 1 and is a labradoodle. I have a two boys, 7 and 6 and I don't work.
I would seriously consider getting an older, rescue dog. If I had my time again that is what I would do. The trouble with a puppy is that you have no idea, none, what kind of temperament your puppy will have once it's grown up and much of that is down to nature and not nurture. So it's almost irrelevant to talk about which breeds are 'good' with children etc, as the honest answer is 'none' - it's down to the individual dog. I thought, wrongly, that rescue dogs are all vicious nasties that no one wants and that rescues wouldn't consider us anyway as we have young children. I now know that to be wrong.
I thought a puppy was a good idea as my children and cats would get along better with a puppy growing up. I was wrong. the children HATED him as a young puppy and the eldest cried and cried and begged for him to be sent back. He hated the jumping and nipping and chasing and that is an inevitable part of the puppy months. The cats hate him too.
Frankly, I really found the early puppy months appalling too. It was worse than having another baby. I lost loads of weight and couldn't sleep, I just could not believe how all consuming looking after a puppy was. And then we had lots of problems with him biting me but that's another issue.
Personally I would never have a puppy again, and certainly not with young children about. I've had to organise all kinds of dog and child care for half term as my children just can't walk the kind of distance the dog needs to be walked every day. It's ok for a few days, but they just can't do it every day! And when the children are home sick from school, or I am sick, it's a nightmare as the dog must be walked regardless or he is so hard to manage in the house as he's still very young. Playdates involve the puppy having the be kept apart from nervous children. All toys must be kept upstairs or he eats them. I could go on...!
I would also never have a poodle mix again. I would look in to cocker rage before considering a cockerpoo.
Next time I'm getting an older dog from a rescue. any kind of dog, I dont' care what breed or what kind of mutt. I just want the right dog for our family and not a puppy that could grow up to be quite the opposite.
