Well our dog Bob is Black Lab Heading dog x (we're not 100% sure about the heading dog but, but he is definitely not a full lab). And Mum I believe is a Bull Mastif. Will clarify that when the neighbour comes over. So she's probably going to be a medium-large dog. I don't know how old puppy is yet, I haven't seen the mum for probably 3-4 weeks so I assume she's around that age.
I think we are reasonably strict owners. We never let Bob roam the streets, if he's off his chain, he is supervised. We don't tolerate barking incessently. We've managed to train Bob to know that if he's barks excessively, we knock on the window and point, that means to shut up and get inside his kennel. He knows "up" means to jump up on to the deck of the ute. He knows "off" is to get off the deck of the ute.
Exposing the puppy to kids could be a problem, we don't have any! But we have plenty of cats so thats not going to be a problem.
We have a house on just over 1/4 acre in a small rural town, is that big enough?? We often take Bob to the reserve or the river for a big run around though.
In regards to the training, I guess i want her to just be a well behaved dog. Not barking constantly or destroying things all over the show. Toileting in appropriate places, behaving while out walking etc.
A short lead is one that is short?? I don't like those long ones that basically let the dog go all over the show. I like them to walk beside me.
