We have a bitch who is going on 7. We got her when she was 7 months. I love her. I am a SAHM. I had to toilet train her by just sitting out with her every time she went out and not letting her out of the designated area until she did something useful. It was the middle of winter and I have treated it as childbirth- the memory has blurred.
She thrives on routine. She is fed at the same point in the morning and evening routine and she is happy. She is walked every morning and she is happy. She knows much of my routine in the car re dd/school runs/ clubs etc. However, take her out of the routine and Sheldon arrives and explodes. It's hugely funny and solved by letting her out to smell.
She came from a home that had had a bloodthirsty event. So she knows how to hunt. She isn't walked off the lead. Where I walk has a bush block attached and she started taking herself in there and I haven't the time to call her off whatever her nose tells her.
She has also been known to take against other dogs for (as far as I can see) no reason. She needs to be controlled (cannot be trusted 100%). She is walked with other dogs regularly and I just introduce new dogs very carefully. She cannot be guaranteed to take the backward step.
She is quite food motivated which is useful. We have a decent sized back yard so I can scatter treats or leftovers chopped finely and she will spend a happy little while hunting them out.
We are able to leave her in the house for some hours with no problems. Her bladder works very well! She isn't a fan of hot weather (a problem in a Perth summer) so thankfully she lives with aircon.
I have her trained with manners well enough that kennels always compliment me when I collect her but I don't think I have gone overboard in expecting obedience. I have never asked her to heel as I prefer her to do the terrier searching thing as we walk. But crossing roads, being served meals, sharing doorways nicely etc are enforced with standard commands through the family. She is eager to please, mostly.
She barks at everything new. However, it means that the neighbours do check the street if she doesn't shut up. The street had NBN installed which took months of blokes driving into our driveway, walking the street etc. Early on, I took her out on the lead a couple of times for an introduction and a sniff and she became happy and quiet. I did repeat it a couple of times as the months wore on and it worked a treat.
I remember the first time I met a BT. It was a baby and dumped into my lap and I remember just picking it up and saying "Oh, boss, I'm in love". So gorgeous. I remember the first time that pup went where it shouldn't have (aka I lost it) and the way it came running back and it's face just said it had stories to tell!. I remember then saying to the boss "don't let it kiss you - I don't know what it has had it's mouth".
Enjoy yours.
