owners of 'big' dogs, can you talk to me please

[bunnyfears]

I have an 18 month old rottweiler. she is a big smooch. she loves all other dogs and most people. her recall is 98% great.

she does 3 things that are undesirable...

1. she will bark at some passersby if she is sat in the car (waiting to leave). I can live with this

2. if a man takes her by suprise, she will bark. so for example, appearing out of the bushes, in the woods etc. I'm pretty ok with this also, because we got her for safety having encountered too many weird men out walking/intruder (me and 3 daughters)

3. she will chase after male runners and bark 😬...this is the one that is getting us into trouble. it's not aggressive but it definitely sounds aggressive if you don't really know dogs. many people are great, stop running, give her a fuss and it diffuses into nothing. but as you can imagine, some people are furious. I don't really want to keep her on a lead because 1) it happens maybe once a fortnight (haven't worked out what it is about some men that brings this response as opposed to others that she ignores or can be distracted from and 2) it's ot actually aggressive

because it's not consistent I'm at a bit of a loss

interested in other people's experiences and how they have dealt with inconsistent/occasional unwanted behaviours

I was chatting to a police dog handler once. He said his dog had perfect recall ... unless a bunny flashed past and it'd be off like a deaf rocket!

We have a lab/german shep cross. He's a big lad, his recall in 95% great. The other 5% involves him chasing cate/dogs/squirrels. He genuinely just wants to play but is huge and barks.

Because of this he stays on lead unless we are on a remote /empty/private field. We don't risk it. It's not fair to other people/dogs
