My three are all very bonded to me as it's just me and them and I do absolutely everything for them but Tilly does tend to like men, she's a real flirt and once she's got to know a man she'll be all over them like a rash. She and my friend Steve who's the bloke she would have seen the most until we moved have a total mutual appreciation society going on and now we're at home when my Stepdad comes home from work she waggles around his legs and then sits batting her eyelashes at him (literally, she really does bat her eyelashes

) although she still always comes back to me and does everything I ask rather than actually listening to the men, she just likes to make them feel like they're important... she's got it well sussed

I really wouldn't worry too much about this, try to relax as Louise said and spend as much fun time with her as you can, fun, positive training in particular can be very bonding for dogs and their owners.
