Hi i have a male bulldog 18 months old when ever i go to take him out for a walk he does every thing he can to avoid going as soon as he hears is lead he hides away in his kennel. But once he's in the park he loves it is this a common thing in male bulldogs as i have 2 bitches and thy love going out.

I have a male bulldog and he always loves going for walks, he goes to the door as soon as i pick his lead up.

Maybe there's something on the way to the park that's upsetting him - perhaps a home with a dog that goes bananas when you walk past, or a particular smell - maybe you're passing through another male dog's patch and it's making your guy anxious.  Has anything happened to him on the way to the park in the past that upset him?

On another line of thought, perhaps he associates the lead with something bad (I'm assuming he's off-lead at the park) - corrections from you, or an incident where it got tugged by accident or caught on something, so now he associates it with unpleasantness.
