*I'm not over-keen on the 'ankle-biter breeds' - I've had TWO Jack Russells in the past, and found them to be far nastier than any GSDs that I'd previously owned.*
Why would you have 2 Jacks if you find them to be nasty?
At that time, I lived in a house with a smallish garden - certainly no place for a larger breed to be cooped up inside.
We got JR1 as a puppy from a neighbour whose 'bitch' had a litter that they needed to home at 8-10weeks. Having taken him on, we found him to be a lovely dog WITHIN OUR OUR HOME - but outdoors he seemed to think that every other dog was a challenge to be beaten and 'the bigger, the better'. He had a similar outlook with taxis (black cab style) / buses / lorries. I had to double-check the local dog-walking field before going on there with him when it came to walkies - but I didn't let him off-leash. He had one of those retractable leads where you could 'halt their progress' as they tried to leave you, while you could 'home in on them' shortening the lead at each movement. He was good with myself, my husband and my children - who all knew better than to over-excite him when playing. We needed to have him put to sleep due to a health issue and thought we'd try again. It was good to have a dog around, as we lived on a Housing Estate where houses were very often burgled.
JR2 was very similar to JR1 but not quite as 'nippy' though he had a thing about 'boys on bikes' (poor paper boy!) and 'milkmen/postmen/binmen' - all people who came to our home to leave something (post/paper/milk). We had to establish a very strict regime of locking him in one room, before opening the door that lead into the hallway/front door. Next-door had a female Dobermann that he was totally besotted with - definitely a 'changed creature' in her very regal presence. We had him for about 10yrs and he proved to be an excellent guard dog - we were one of the few houses NOT to get broken into. He was run over after one particular escape attempt' and unfortunately didn't survive - I was devastated on behalf of the Lorry Driver who actually hit him.
I've never had another dog since that one - had a cat for 14years instead.
I've now developed a 'reaction to pet fur/dander' to that's the end of my pet owning .
