Hi everyone! So my dog is a year old and used to have no problem walking off lead. Me and my partner take him to the local dogs only park once a week, where the dogs play and chase each other and have fun. Since then we cannot let him off the lead on our usual walk as he will chase any dogs he sees, not listen to us and follow other dogs. He’s becoming a nightmare to walk as he will cry and pull whenever a dog walks past. Even in the garden, if he hears another dog he will Howl and not settle for an hour or so. He is not food motivated in the slightest so will not settle even if we give him treats to distract him. Any training tips will be much appreciated!
