Sounds bad to be so judgemental, but day after day at the park, the most misbehaved dogs tend to be owned by those who sit at dog parks and chat, smoke, bring random lawn chairs etc…
The breeds of dog also tend to be the same, ‘pitbullish’ style or cane Corso, or those dogs so small and yappy.
It’s somewhat frustrating. If I see more then 1 or 2 people sitting, I know there is most likely going to be some altercation between dogs and there usually is…
Is it the same in your area?
Our trainers when showing us the dog park told us to always keep moving. The dog covers new ground and gets distracted and entertained by new smells and doesn’t annoy dogs with overexposure because they are forced to make short visits.
They say people who were standing still risked encouraging bad behaviour by comparison so avoid the people and dogs standing still.
So this tracks.
