I have a former bait dog that is wonderful with other dogs unless they show dominance.At that point he goes into full meltdown mode.shakes,tail between legs and tries to hide.It can be a lil poodle that scares him too,doesn’t mattter the dog’s size.I feel so bad he gets so excited seing other dogs,but i never know what is going to trigger him.Any suggestions on helping my boy work through his fears?
