OK...I have 2 dogs, and when I am by myself, I can only walk one at a time-obviously. My PBT Rosie, who just turned 1 year, has started this new thing when we go for a walk. She is typically very very sweet, and is well behaved. Lately, If we encounter another dog(s) on our walk, she immediately becomes on the defense and if the dogs approach us, she automatically thinks they want to fight-which has been the case most of the time. I do not know who lets their dogs out unsupervised, and if there are multiple dogs that approach us, it is difficult for me to break them up and try to leave. Rosie is VERY VERY strong, and wears a harness and short leash. I tell her "No" and she ussually obeys, unless there is another dog approaching. Can anyone give advice on what to do on our walks? My other dog isn't like this, and is very submissive and nervous when another dog approaches. Thanks in advance for anything helpful!
