I have an 18 mo lab cross. He's gorgeous, friendly, non aggressive, great around our cats and children. Never been aggressive blah blah blah…..BUT when I take him to the park if there is anyone there marking out white lines for a sports pitch, mowing a lawn, hoovering up leaves etc. he goes nuts! In a "wow! this is great - let's play!" type way. Not in an aggressive "I'm going to kill you," way. The problem is that he has twice gone charging over the the white-line man and starting barking his head off and nudging the white-line man to get him to move the paint machine thing. Now obviously white line man objects to a dog coming haring across the field and barking at him to play and he has reported my pup to the dog warden for biting him. My dog DID NOT bite the white line man - he nudged and pulled/nipped at his clothes to get him to move the white-line marker thing so he could play. This has happened twice in the last 3 months or so but it is completely ruining my dog walking experience (all my doggy walking friends congregate there) and I have taken mutt elsewhere to get his exercise. A muzzle has been suggested in case the white line marker man is there but I really really don't want my dog muzzled as this is literally the ONLY thing he gets excited over! Please wise m-netters advise me. The dog warden advised the white line man to report my dog to the police and I feel gutted :-((((
