I have a reactive dog. I love her to bits and get much pleasure from her.
If I want to let her off (and I try to because she's a huge high energy breed) I have to walk her in remote areas and have to be hyper diligent that no dogs are around. I've never made a mistake so far and she's 7 but I am lucky to live near a large country park and if I pick early morning/after dusk It's usually fine. She also has partial sight and good recall so as long as I spotted any other dog before she did it'd be okay.
I can't and wouldn't take her to a highly populated area (at least not purposely).
She's very alert and protective and I am a single female who lives alone, I feel I can walk about at night safely with her (visiting parents or going to the local pub). If there are dogs in the pub and I cant sit away from them, I sit outside. If It's very busy, I don't take her (I am friends with enough people in there to be able to text and check, and luckily It's a very dog friendly area).
I don't tend to have people over who dog doesn't know (not because of dog, but just, I have a small group of friends who all love her and nobody else really comes here) however someone came for a meeting some time ago and I was a bit wary-all I did was let them meet her outside first and she was excited and liked them. Fine.
Another time I had some work done in the house and the two workmen, I kept her out of their way obviously but I did have them both give her a treat when they first came in . I may have looked a bit bonkers but It's better than her not trusting them.
She's very loving, very intelligent and a lot of fun.
Strangely, today I was running with her (on lead) in a field and two dogs came bounding up, owner nowhere to be seen. I had ran the whole length of one field and was in a different one before he appeared, but they were running around her, bounding, she snapped at one and it snapped back-luckily that was that. I just kept talking calmly to her as she was scared despite said dog being half her size .
But yes, I do get pleasure from my dog, although obviously I'd much rather she wasn't as reactive as she is. I truly believe I could have done nothing about her nature, too-she was fine up until a certain age and then it just began happening. I used to be able to let her off all the time no problem at all. It could have been something to do with me or the lifestyle I have or something that happened, but I don't know what so even if I could turn back time I'd be as likely to do/not do whatever it was again.
