I am having daily issues with younger dogs at the park and owners telling me off/ labeling my dog as unfriendly. One dog (a lurcher mix) is let off the lead and runs over to every dog at full speed- my dog will accept it coming over but after a few minutes of it in his face I can see he gets a bit tense so I call him away and we walk off. At one point my dog was lying down with a ball and the dog came running over at full speed behind my dog so I blocked it and said No, this caused a massive argument with his owner! I was trying to prevent a fight with a dog that I think has no boundaries, especially as my dog was exhausted and had a ball which he may guard. A few days ago a puppy was let off the lead and followed my dog around for 15 mins, he ignored it but when he sat down the puppy started to lick his face and jump over him- my dog snapped at him and walked to me. I instantly put him on a lead, the puppy didn't cry out or seem afraid but the owners were not impressed. (I did say sorry) My dog is nearly 2 and is not dog orientated (which I wanted) he has a small group of dogs he loves and will play with, others he will greet and walk on. Its getting a bit stressful walking him now and I'm a bit sad my dog is being labeled as a problem dog at the park, but maybe he is?
